This power pack provides 7.2 volts and can operate your transceiver at 2.5 watts(typical power) with the low power button out. As supplied, the power pack is fully discharged. You need to fully charge the pack using the supplied charger before you operate the transceiver from the rechargeable pack. Follow these steps to charge the pack. 1. If the pack is attached to the transceiver, turn off the transceiver. Do not operate the transceiver while charging the pack. NOTE: You can remove the power pack from the transceiver to charge it, and operate the transceiver from one of the other power sources. 2. Plug the supplied charger's barrel plug into the CHARGE jack on the back of the power pack. 3. Plug the charger into a standard AC outlet. The CHARGE indicator lights. It takes about 10 hours to charge the power pack. When power is low, BATT appears on the display when you press PTT. You can buy extra power packs through your local Radio Shack store. NOTES: Nickel-cadmium batteries deliver more power if you occasionally let them completely discharge. To do this, use the transceiver until BATT appears on the display when you push the PTT. Then fully charge the batteries. If you do not occasionally do this, the batteries temporarily lose the ability to deliver full power. Also, to ensure a full charge, be sure the batteries are at room temperature (above 65 degrees F) when you charge them. Cold batteries do not fully charge. Even when the battery is fully charged, the battery power meter will not read full scale. However, it will indicate full scale when being powered from the cigarette lighter adapter. CAUTIONS: To prevent permanent nickel-cadmium power loss, never charge the power pack in an area where the temperature is above about 80 degrees F. Never use a charger other than the one supplied to charge the power pack. Even chargers with the same voltage and current ratings could permanently damage the transceiver or the power pack. You can order a replacement charger at your local Radio Shack store. USING ALKALINE BATTERIES You can operate the transceiver from 6 AA alkaline batteries (not supplied) using the supplied alkaline battery holder. This battery holder supplies 9 volts and can operate your transceiver at 4 watts (typical power) with the low power button out. Follow these steps to load or replace batteries in the alkaline battery holder. 1. Hold the outer battery holder case and push down on the center of the battery holder. 2. Remove old batteries, if necessary, and install six fresh AA alkaline batteries, observing the correct polarity as indicated by the markings (+ and -) in the battery holder. 3. Press the battery holder into the battery holder case. When power is low, BATT appears when you press PTT. Be sure to use six fresh AA alkaline batteries. Never mix different types of batteries, and never mix old and new batteries. OPERATING FROM VEHICLE BATTERY POWER You can operate the transceiver from vehicle battery using a DC power cord (Radio Shack Cat. No. 270-1533). This cord supplies a 13.8 volts (typical) to your transceiver and can operate your transceiver at 6 watts (typical power) with the LOW POWER button out. Follow these steps to operate from the vehicles battery power. 1. Plug the power cord's barrel plug into the transceiver's EXT DC jack. CAUTION: Never plug the power cord into the rechargeable power pack's CHARGE jack. Doing so can damage the power pack and the transceiver. 2. Plug the power cord's cigarette-lighter plug into your vehicle's cigarette-lighter socket. If the transceiver does not operate, remove the power cord's plug from the cigarette-lighter and check for debris. Clean the socket, if necessary, and try again. OPERATING FROM AC POWER You can operate the transceiver from AC power using either the 1-amp 12 volt DC adapter(Cat. No. 273-1653) or our regulated 2.5-amp power supply (Cat. No. 22-120). The 2.5-amp power supply lets you operate your transceiver at 5 watts (typical power) with the low power button out and is better isolated from 60 Hz noise. The 1-amp adapter connects very quickly and requires no soldering but only operates your transceiver at about 2 watts with the LOW POWER button out. Follow these steps to power the transceiver from the 1-amp, 12 volt DC adapter. 1. Connect the barrel plug with the tip set to positive. 2. Insert the adapter's barrel plug into the transceiver's EXT DC jack. CAUTION: Never insert the adapter's barrel plug into the rechargeable power pack's CHARGE jack. Doing so can damage the power pack and transceiver. 3. Plug the adapter into an AC outlet. Follow these steps to power the transceiver from the regulated 2.5 amp power supply. NOTE: You need the following materials to use the regulated 2.5 amp power supply: Power supply (Cat. NO. 22-120) Two-conductor 18-gauge wire (Cat. No. 278-5670 DC power connector (Cat. No. 274-1567) Soldering iron and solder Volt meter or multimeter 1. Cut the two-conductor wire to the length power cord you need. 2. Strip about 1/2 inch of insulation from each end of both conductors. 3. Solder one end of the wire to the DC power connector, with the red lead connected to the center terminal, and the black lead connected to the outer casing. 4. Melt a small amount of solder onto the other end of the wire. Then, connect the red lead to the power supply's + terminal and connect the black lead to the power supply's - terminal. 5. Plug in the power supply and turn it on. Use the meter to confirm you have correctly wired the power connector so that the tip is + and the case is -. 6. Turn off the power supply and plug the connector into the transceiver EXT DC jack. CAUTION: Never plug the power connector into the rechargeable power pack's CHARGE jack. Doing so can damage the power pack and the transceiver. 7. Turn on the power supply. BACKUP BATTERY Your transceiver uses a lithium battery to keep stored options in memory when you disconnect the transceiver from a power source. This battery should last 3 to 5 years, under normal conditions. When the transceiver frequently displays ER1, the back up battery needs to be replaced. NOTE: To clear the error, reset the transceiver. See "Resetting the Transceiver." The backup battery is not user-serviceable. Take the transceiver to your local Radio Shack store to have the battery replaced by a Radio Shack repair center. This product contains a rechargeable nickel-cadmium (lead acid) battery. At the end of the battery's useful life, it must be recycled or disposed of properly. Contact your local, county, or state hazardous waste management authorities for information on recycling or disposal programs in your area. Some options that might be available are: Municipal curb-side collection, drop-off boxes at retailers, recycling collection centers, and mail back programs. CONNECTING THE ANTENNA Your transceiver comes with a flexible antenna. You must connect an antenna to your transceiver before you transmit. The transceivers BNC antenna connector is easy to connect other types of antennas. Radio Shack stores sell a 5/8 wave magnetic mount antenna for mobile operation (Cat. No. 19-210), a discone antenna (Cat. No. 20-013), and a center-loaded telescoping whip antenna (Cat. No.20-006) that you can use with your transceiver. To use the supplied antenna, slip the antenna's connector over the BNC jack and twist the antenna to lock it in place. To use an external antenna, if necessary, attach the appropriate connector adapter to the end of the antenna cable. Then, slip the connector over the BNC jack and twist the connector to lock it in place. WARNING: When installing or removing an outdoor antenna, use extreme caution. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches the power line, contact with the antenna, mast, cable, or guy wires can cause electrocution and death! Call the power company to remove the antenna. Don't attempt to do so yourself. ATTACHING THE BELT CLIP You can attach the provided belt clip to your transceiver. Use the supplied screws. ATTACHING THE HAND STRAP Loop the supplied hand strap's key ring through the hand strap tab. USING AN EXTERNAL MICROPHONE You can use an external microphone with your, transceiver. When you connect an external microphone, the internal microphone does not work, but the internal PTT is not affected. If your microphone has a 3/32 inch(2.5 mm) submini plug, plug the microphone cable into the transceiver's MIC jack. USING AN EXTERNAL SPEAKER In a noisy area, an external speaker, positioned in the right place, might provide more comfortable listening. Radio Shack stores sell an extension speaker (Cat. No. 21-549) and an amplified communication extension speaker (Cat. No. 21-541). Plug the speaker cable's 1/8 inch(3.5 mm) mini plug into the transceiver's SP jack. This disconnects the internal speaker. For the most efficient operation when you carry the transceiver on your belt, connect a combination speaker/microphone (such as Cat. No. 19-310) to your transceiver and hang the mic/speaker on your collar. If your vehicle has a cassette player, you can easily connect your transceiver to your vehicle's audio system using a CD-to-cassette adapter (Cat. No. 19-1951) and a mono-to-stereo audio plug (Cat. No. 274-368). Simply insert the adapter in your vehicle's cassette player, connect the adapter's plug to the mono-to-stereo plug, insert the plug in the transceiver's SP jack, and turn on your cassette player. USING THE TRANSCEIVER WITH PACKET RADIO You can connect your transceiver directly to a packet radio terminal mode controller. RESETTING THE TRANSCEIVER When you first use the transceiver, if the transceiver displays ER1, or if you ever want to reset the transceiver's options to the factory defaults and clear all memories, follow these steps. WARNING: This procedure clears all the stored information from the transceiver. 1. Turn off the transceiver. 2. Press and hold down F+CLR. Then, turn on the transceiver. USING THE LIGHT Press L on the side of the transceiver to turn on the display light for about 5 seconds. To turn the light off sooner, press L again. The light stays on until you press L or turn off the transceiver. Operation SETTING SQUELCH AND VOLUME Rotate VOLUME clockwise and SQUELCH counterclockwise until you hear a hissing sound. Then, slowly rotate SQUELCH clockwise until the noise stops. Leave VOLUME set to a comfortable level. If the transceiver picks up unwanted weak transmissions, rotate SQUELCH clockwise to decrease the transceiver's sensitivity to signals. SELECTING A FREQUENCY You can use any of three methods to select a frequency to communicate on. Direct entry Tune control Scanning for frequencies TUNING USING DIRECT ENTRY Your transceivers transmits and receives on frequencies between 144.000 and 148.000 MHz. To quickly tune to a frequency, enter the frequency using the keypad. 1. Turn on the transceiver. 2. Press VF. 3. Use the keypad to enter the last four digits of the frequency. For example, to enter 146.940, press 6940. NOTES: If you make a mistake, press CLR and repeat this step. The transceiver rounds the last digit down to 0 or 5. TUNING USING THE TUNE CONTROL You can quickly tune to a nearby frequency by rotating TUNE on top of the transceiver. 1. Turn on the transceiver. 2. Press VF. 3. Rotate TUNE counterclockwise to tune down or clockwise to tune up. The transceiver tunes up or down one frequency step per click, see "Setting the Frequency Rate." SCANNING FOR ACTIVE FREQUENCIES You can scan for activity on a frequency by pressing and holding down /\SC or \/SC for at least 1 second. The transceiver begins to scan up or down the full frequency range, and stops on active frequencies. To scan only a selected frequency range press F+/\SC or F+ \/SC. See "Setting the Scan Options" to see how to change the scanning range, the frequency step, the scan resume condition, and the scan delay time. The following are the factory presets for these options. Frequency Step: 15KHz Scan Resume Condition: Resumes scanning in 10 seconds, regardless of absence or presence of a carrier. Scan Delay: Not activated. Scan limits: 144 MHz to 148 MHz To stop scanning, press \/SC, /\SC, CA, PR, VF, or turn off the transceiver. SCANNING FOR A VACANT FREQUENCY In some areas where the 2-meter band is being used heavily, you might have trouble quickly finding a frequency not being used. To quickly scan for a vacant frequency, press F+V - SC. The transceiver scans up or down from the current frequency to the first unused frequency. To change the vacant scan direction, see "Setting the Vacant Scan Direction." RECEIVING TRANSMISSIONS To receive transmissions, turn on the transceiver, adjust the volume and squelch, and tune to a frequency. TRANSMITTING There are two basic types of communication you can use with this transceiver. These types are sometimes referred to as SIMPLEX and DUPLEX. With simplex transmissions, you transmit and receive on the same frequency. With duplex transmissions, you transmit on one frequency and receive on another. Duplex transmission is the communication type you use when you communicate using a repeater. You transmit to the repeater on one frequency (the input frequency), and the repeater retransmits the signal at a different frequency (the output frequency). CAUTION: Do not transmit if you do not have a Technician Class or higher license issued by the FCC. Doing so is illegal. Follow these steps to communicate using simplex communications. 1. Turn on the transceiver. 2. Select the desired frequency. 3. If + or - is on the display, repeatedly press F & + / - until neither symbol appears. 4. Press LOW POWER so that the button is down. In this position, your transceiver transmits at about 1 watt. 5. Begin communications. If the other party advises that you need to improve your signal (QRO), press LOW POWER so that the button is up. In this position, your transceiver transmits at the highest power it can, depending on the power source. Remember to switch back to low power whenever possible, to comply with the FCC rules that require you to use the minimum power necessary to maintain communications. Follow these steps to communicate using duplex communications. 1. Turn on the transceiver. 2. Tune to the desired receive (output) frequency. 3. If the transmit (input) frequency is 600 kHz ABOVE the receive frequency, press F+ +/- so that the + appears in the display. If the transmit frequency is 600 kHz BELOW the receive frequency, press F+ +/- so that - appears on the display. If the frequency separation is not 600 kHz, either set a new default frequency or store the frequency pair in one of the scanner's memories (See "Using Memory Channels" and "Setting the Duplex Separation"). LOCKING THE KEYPAD To lock the transceiver's keypad so that you do not accidently change a setting, press F+LOCK. LOCK appears on the display. This locks all front- panel buttons and the tune control. The PTT, VOLUME, and SQUELCH still operate. To release the lock, press F+LOCK again. SETTING THE KEY ENTRY BEEP Each time you press a key, the transceiver sounds a beep. To turn off the beep, press F+BEEP. The key beep does not sound this and subsequent key presses. To turn on the key beep, press F+BEEP again. REVERSING THE OFFSET To reverse the transmit and receive frequencies when you are operating duplex, press F+REV. For example, if you are set to 146.94 with a - offset pressing F+REV makes the transceiver receive on 146.14 and transmit on 146.94. USING MEMORY CHANNELS Your transceiver has 16 memory channels in three groups. One calling-frequency memory Three priority-frequency memories 12 standard memories USING THE CALLING-FREQUENCY MEMORY The calling-frequency memory provides a single memory that you can quickly jump to at any time. Follow these steps to save a frequency in the calling-frequency memory. 1. Press VF. 2. Tune to the frequency you want to save. 3. Press CA. 4. If the frequency is for a repeater that requires subaudible tone access or if you want to use incoming subaudible tone squelch with frequency, press F+T-SQL so that T-SQL appears on the display. NOTE: If you turn on T-SQL you must correctly set both the transmit subaudible tone as described in steps 8 through 11. 5. Press and hold down F+M-WR for at least 1 second. The transceiver stores the tuned frequency in the calling-frequency memory, plus the frequency separation (for duplex operation) and subaudible transmit and receive tones. For more information about subaudible tones, see "Using Subaudible Tone Squelch" (CTCSS)." 6. If you want to set a different transmit frequency or change the subaudible tones, press F+M-SET. The transceiver displays TF followed by the transmit frequency. 7. Rotate TUNE to change the transmit frequency. 8. To set a transmit subaudible tone frequency, press \/SC. The transceiver displays TC followed by the transmit subaudible tone frequency. 9. Rotate TUNE to change the transmit frequency. NOTE: If you do not want to transmit subaudible tone, rotate TUNE to set the transmit subaudible tone to OFF. 10. To set a receive subaudible tone frequency, press \/SC. The transceiver displays RC followed by the receive subaudible tone frequency. 11. Rotate TUNE to set the receive subaudible tone frequency. NOTE: If you do not want to use incoming tone squelch, rotate TUNE to set the receive subaudible tone to OFF. Otherwise, you do not hear transmissions unless the subaudible tone is present. 12. Press the PTT to save the settings and return to the calling- frequency memory display. To use the calling frequency memory, press CA at any time. The transceiver immediately goes to the calling frequency and sets the transmit frequency, subaudible tones, and tone squelch to the settings you programmed. To return to the previous settings, press CA again. USING THE PRIORITY-FREQUENCY MEMORIES The transceiver has three priority-frequency memories. The transceiver can periodically scan these frequencies during manual, calling-frequency memory, or standard memory operation. Follow these steps to store a frequency in the priority-frequency memories. 1. Press press VF and tune to the frequency you want to save. 2. Press F and rotate TUNE until either P1, P2, or P3 appears to the left of the tuned frequency. 3. If the frequency is a repeater that requires subaudible tone access or if you want to use subaudible tone squelch with this frequency, press F+T-SQL so that T-SQL appears on the display.] 4. Press F+M-WR for at least 1 second to store the tuned frequency in the selected priority-frequency memory. 5. To change the frequency separation or subaudible tones, press PR and rotate TUNE to select the priority-frequency memory you want to change. Then, refer to steps 6 through 12 under "Using the Calling-Frequency Memory." Each priority frequency can have different settings. To set the transceiver to a priority frequency, press PR. Then rotate TUNE, press /\SC, \/SC, 1, 2, 3, to select one of the three memories. To have the scanner check the priority-frequency memories for activity, press VF. Then, press F+P-SC for at least 1 second. The transceiver checks the priority-frequency memories every 4 seconds. To change the priority scan time, see "Setting the Priority Scan Time." To continuously scan the three priority frequency memories, press PR. Then, press and hold down /\SC or \/SC at least 1 second, NOTE: You must store more than one priority frequency in memory to continuously scan priority-frequency memories. USING THE STANDARD MEMORIES Your transceiver has 12 standard memories into which you can store frequently-accessed frequencies for quick access. Follow these steps to store a frequencies in standard memories. 1. Press VF and tune to a frequency you want to store. 2. Press F and rotate TUNE until the memory number to the left of the frequency display shows the standard memory you want to store into. 3. Press F+M-WR for at least 1 second to store the tuned frequency into the selected standard memory. 4. To change the frequency separation or subaudible tones, press MR and rotate TUNE to select the standard memory you want to change. Then, refer to steps 6 through 12 under "Using the Calling-Frequency Memory." Each standard memory can have different settings. To set the transceiver to a standard memory, press MR. Then, rotate TUNE or press /\SC or \/SC to select one of the 12 memories. To continuously scan standard memories, press MR. Then, press and hold down /\SC or \/SC for at least 1 second. NOTE: The transceiver stops scanning according to the scan options you have set. See "Setting the Scan Options" for more information. CLEARING MEMORIES Follow these steps to clear a memory. 1. Press PR or MR and select the memory you want to clear. 2. Press F+M-CLR to clear the settings stored in the current memory. NOTE: You cannot clear Standard Memory 1 or the calling-frequency memory. You can only change the settings for these memories. MOVING A MEMORY CHANNEL TO THE MANUAL MODE Follow these steps to quickly move a memory channel to the manual (VF) mode. 1. Select the memory channel. 2. Press F+M-VFO. All settings for the selected memory move to the VF mode. REVIEWING PROGRAMMED OPTIONS Follow these steps to view the transmit frequency and subaudible tone settings for a memory or the tuned VF frequency. 1. Press CA, PR, MR, or VF and select the memory or frequency you want to check. 2. If you want to check the subaudible tone settings, press F+T-SQl so that T-SQL appears on the display. 3. Press M (located above PTT). The transceiver's squelch opens, and the display shows the transmit frequency for about 1 second, followed by the subaudible transmit tone and the subaudible receive tone. UNDERSTANDING THE CONFIGURATION MENU Your transceiver has a configuration menu that lets you modify operation settings. Each of the following sections explain how and when to use each configuration menu and select options. 1. Press VF. 2. Press F+M-SET. The first menu item appears. 3. Press \/SC or /\SC to step down or up through the menu items. Rotate TUNE to change the menu settings for any menu item. 4. Press PTT to exit the configuration menu and save all settings. The configuration appears in the following order: CODE FACTORY DEFAULT EXPLANATION oS 0.600 Duplex separation (offset) tc oFF Transmit subaudible tone rc oFF Receive subaudible tone Sr 15 Frequency step Sc ti Scan resume Sd 2.0 Scan delay time S1 144.000 Lower scan range limit S2 148.000 Upper scan range limit ud dn Vacant channel scan direction PS 1-16 Power save duty cycle tE oFF Transmit inhibit to oFF Transmit time-out Lb 4 Priority-frequency channel lookback time Ar oFF Touch-tone auto-reply SETTING THE DUPLEX SEPARATION DEFAULT The duplex separation default (offset) controls the offset between the transmit frequency and the receive frequency when you use the transceiver in duplex mode, as with a repeater. Typically, on the 2-meter band, repeaters receive at a frequency 600 kHz lower or higher than they retransmit (repeat) on. For example, if a repeater's input frequency is 146.340 MHz, its output frequency is 146.949 MHz. The following is a list of the most commonly used repeater pairs. INPUT FREQUENCY OUTPUT FREQUENCY 146.O7 MHz 146.67 MHz 146.13 MHz 146.73 MHz 146.16 MHz 146.76 MHz 146.22 MHz 146.82 MHz 146.25 MHz 146.85 MHz 146.28 MHz 146.88 MHz 146.31 MHz 146.91 MHz 146.34 MHz 146.94 MHz 146.37 MHz 146.97 MHz 146.40 MHz 147.OO MHz To operate with a repeater, you must transmit on the repeater's input frequency and receive on the repeater's output frequency. If you frequently use a repeater that does not have a 600 kHz offset, we recommend you program the repeater frequency into one of the transceiver's memories. You can override the default offset for each memory. To change the default offset, follow the steps in "Understanding the Configuration Menu." to display the oS menu item, and rotate TUNE to change the offset. The transceiver lets you set the offset to be in the range from 0 MHz to 4 MHz in steps as set by the frequency step option. USING SUBAUDIBLE TONE SQUELCH (CTCSS) Some repeaters require that you transmit subaudible tone to key-up the repeater. You can set your transceiver to transmit any of the 38 standard subaudible tones. You can also limit incoming calls by setting your transceiver to open the squelch only when someone transmits a subaudible tone you set. ---------------- ---------------- | tc oFF | | rc oFF | ---------------- ---------------- To set a subaudible transmit tone, follow the steps in "Understanding Configuration Menu" to display tc. Then, rotate TUNE to select the subaudible tone. If you do not want to transmit a subaudible tone, rotate TUNE to select OFF. To set a subaudible receive tone, follow the steps in "Understanding the Configuration Menu" to display rc. Then, rotate TUNE to select the subaudible tone. If you do not want to use the receive subaudible tone squelch, but are using transmit subaudible tone to activate a repeater, rotate tune to select OFF. Otherwise, you only hear transmissions that have the correct subaudible tone when you activate tone squelch. To turn on the subaudible tone feature, press F+T-SQL. When you transmit, the transceiver includes the subaudible tone in the signal. To receive, the incoming signal must have the correct subaudible tone.

The following sections describe how to set the frequency step rate, the scan condition, the scan delay duration, and the scan limits. SETTING THE FREQUENCY STEP RATE The frequency step rate affects the scanning mode, the TUNE control, and /\SC or \/SC tuning. The factory default for the frequency step is 15kHz. Each time you rotate TUNE one click or \/SC or /\SC the frequency changes by 15 kHz. When scanning, the transceiver scans up or down 15 kHz step. To change the frequency step rate, follow the steps in "Understanding the Configuration Menu" to display the Sr menu item, and rotate TUNE to change the frequency step rate. You can set the step rate to 5, 10, 15, 25, 50, or 100 kHz. SETTING THE SCAN RESUME CONDITION When you have set the transceiver to receive either standard memories or VF mode, the transceiver stops whenever it encounters a signal strong enough to break squelch. At the factory setting, the transceiver resumes scanning in 10 seconds, regardless of the of the presence of a continued signal. You can set the scan resume configuration item to one of the following. ti Resumes scanning in 10 seconds cr Resumes scanning after the carrier drops and the scan delays expires (See "Setting the Scan Delay.") SE Does not resume scanning To change the resume condition, follow the steps in "Understanding the Configuration Menu" to display Sc. Then, rotate TUNE to select the resume condition. NOTE: The resume option does not affect the priority scan. Priority scan always resumes scanning after the carrier drops. SETTING THE DELAY DURATION When you set the scan resume condition to cr (carrier), the transceiver resumes scanning after the carrier drops. The scan delay option lets you set the transceiver to pause before resuming, so you can hear any reply. The factory default for this option is 2 seconds. To change the scan delay duration, follow the steps in "Understanding the Configuration Menu" to display Sd. Then, rotate TUNE to select the scan delay duration. You can set the delay to 0.5, 1, 2, or 4 seconds. NOTE: The scan delay option also affects priority scan. SETTING THE SCAN LIMITS When you press F+\/SC or F+/\SC the transceiver scans only those frequencies within a range you set with scan limit options. To set the scan limits, follow the steps in "Understanding the Configuration Menu" to display S1. Use either TUNE or the key pad to enter one of the frequency limits. Then, press \/SC to display S2 and enter the other frequency limit. You can enter the higher frequency as either limit. SETTING THE VACANT SCAN DELAY The transceiver's factory default for vacant scan is to scan down until it finds an unused frequency. To change the vacant scan direction, follow the steps in "Understanding the Configuration Menu" to display ud. Then, rotate TUNE to select either UP or DN. USING THE POWER SAVE FEATURE To set the transceiver to save power press F+SAVE so that SAVE appears on the display. In the power-save mode, the transceiver turns on the receiver for about 32 milliseconds to check for any activity, and then turns off the receiver for the time you set with the power-save configuration setting. The factory default for this setting is to use only 1/16 normal power. To change the power save setting, follow the steps in "Understanding the Configuration Menu" to display PS. Then, rotate TUNE to select the power save setting. You can set the power-save setting to 1-2, 1-4, 1-8, or 1-16 (1/2, 1/4, 1/8. or 1/16 normal power usage. Press F+SAVE again to turn off power save. Power save temporarily turns off while scanning. PREVENTING TRANSMISSIONS To prevent any transmissions using the transceiver, turn on the transmit inhibit function. To turn on this function, follow the steps in "Understanding the Configuration Menu" to display tE. Then, rotate TUNE to select ON. To enable transmissions, set this option to OFF. LIMITING TRANSMISSION DURATION When you communicate on the 2-meter band, you should keep your transmission as brief as possible. Most repeaters have built-in timers that limit single transmissions to 3 minutes or less. You can set the transceiver to stop transmitting and sound a beep if you exceed a set time limit with a single transmission. To set a transmit limit, follow the steps in "Understanding the Configuration Menu" to display to. Then, rotate TUNE to select OFF 30, 60, or 120 seconds. SETTING THE PRIORITY SCAN TIME When you turn on PRIORITY scan, the transceiver checks the preprogrammed priority-frequency memories periodically to see if there is any activity. As factory set, the transceiver checks the priority-frequency memories every 4 seconds. To change the PRIORITY scan time, follow the steps in "Understanding the Configuration Menu" to display Lb. Then, rotate TUNE to select 4, 8, 12, or 16 seconds. USING TOUCH-TONE FEATURES Your transceiver has a built-in 16-key touch-tone encoder. You can manually send touch tones, or send tones from one of the five DTMF memories. You can also set your transceiver so that it is silent until it receives a specific sequence of touch tones. MANUALLY SENDING TOUCH TONES Some repeaters require you to enter a touch-tone code to key-up the repeater. Also, some repeaters have autopatch devises that let you make telephone calls through the repeater. To manually send the required tones, press and hold down PTT. Then, enter the touch-tone digits. NOTES: You must press D twice to send the D digit. If the auto-reply feature is turned off, you can release PTT after you enter the first digit. The transceiver continues to accept and transmit the touch-tone signals until you pause at least 1 second. STORING A DTMF MEMORY SEQUENCE You can store frequently-used touch-tone sequences in the transceiver's five DTMF memories. Each memory can hold up to 15 digits. Follow these steps to store touch-tone frequencies. 1. Press and hold down F+DTMF for at least 1 second. The display changes to show the first DTMF memory. 2. Press D. Then, press a digit from 1-5 to select one of the DTMF memories. 3. Enter the touch-tone sequence. If the sequence is less than 15 digits, press D, then press a digit from 1 to 5 to select a different DTMF memory or press PTT to exit the DTMF memory store mode. NOTE: To enter a D, press D twice. TRANSMITTING A DTMF MEMORY SEQUENCE To send a DTMF memory sequence, press and hold down PTT. Then, press D followed by the DTMF memory number you want to transmit (1-5). The transceiver transmit the tones. The transceiver has two DTMF memory sequence transmit speeds. To switch between fast and slow, press and hold down PTT. Then, press 0. NOTE: If the auto-reply feature is turned off, you can release PTT after you press D. Enter the DTMF memory number within 1.5 seconds. USING DTMF SEQUENCE FOR PAGING The DTMF squelch feature lets you set your transceiver to release squelch only if it receives a specific touch-tone sequence. Follow these steps to set the touch-tone sequence. 1. Press F+D-SQL for at least 1 second. The transceiver displays the previous sequence or - if you have never programmed a sequence. 2. Enter the sequence (up to five digits). 3. Press PTT to save the sequence. To turn on the DTMF squelch, press F+D-SQL for less than 1 second. DTMF appears on the display. Your transceiver remains silent until it receives the correct touch-tone sequence. Then, it beeps and returns to normal operation. To cancel DTMF squelch, press F+D-SQL for less than 1 second so that the DTMF disappears from the display. AUTOMATICALLY SENDING A DTMF REPLY You can set your transceiver to automatically transmit the touch-tone digit (#) when you have enabled DTMF squelch and the transceiver receives the correct touch-tone sequence. To turn on the DTMF auto-reply, follow the steps in "Understanding the Configuration Menu" to display Ar. Then, rotate TUNE to select on. You should also set this option to on if you expect an auto reply from an auto patch or another HTX-202 or other transceiver that has this feature. Care and Maintenance Your HTX-202 2-Meter Handheld Transceiver is an example of superior design and craftsmanship. The following suggestions will help you care for your transceiver so that you can enjoy it for years. Keep the transceiver dry. If it does get wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits. Use and store the transceiver only in normal temperature environments. Temperature extremes can shorten the life of electronic devices and distort or melt plastic parts. Handle the transceiver gently and carefully. Dropping it can damage circuit boards and cases and can cause the transceiver to work improperly. Keep the transceiver away from dust and dirt, which can cause premature wear of parts. Wipe the transceiver with a dampened cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the transceiver. Modifying or tampering with your transceiver's internal components can cause a malfunction and might invalidate its warranty and void your FCC authorization to operate the transceiver. If your transceiver is not performing as it should, take it to your local Radio Shack store. Error Codes Your transceiver has two error code displays. Refer to the following for an explanation of each error code. Er1: INTERNAL RAM ERROR Er1 indicates the transceiver has detected an error in its battery-backed up operation memory. This is the most commonly caused by a low lithium backup battery, but can also be caused by static discharge, or a physical shock. To clear the error-- 1. Turn off the unit. 2. Press FUNCTION and CLR (the D key). 3. While holding these keys, turn unit on. This will reset unit and clear memories. If the transceiver frequently displays the error, have the battery replaced by an authorized Radio Shack service center. ER2:PLL UNLOCK ERROR Er2 indicates the transceiver's PPL section has unlocked. Have the transceiver repaired by an authorized Radio Shack service center. Hints and Tips This radio is likely to get an ERR2 when running off a cigarette lighter. This is due to RF feedback which travels from radio to rubber duck to power cord and back to radio. The best way to fix the ERR2 is to use an external antenna. When pressing f/3, it only comes up with a negative offset. In order to come up with a positive offset, check the offset by entering VFO mode and pressing function/8. The display reads os and a number. That number is normally 600. It will not give any offset that puts it out of the legal limits of 144-148 MHz. This radio cannot be modified for expanded frequencies. htx 202 keypad 1 tone sql 2 dtmf 3 minus direct plus 5 beep 6 reverse 7 save (activates power saving feature while receiving) 8 m-set 9 m-clr star scroll down 0 v-sc pound scroll right a lockand calling frequency ca b p-sc pr(priority scan) c m-wr mr (memory banks and also used for some other memory functions) d vf clr lock and unlock keypad f plus a calling frequency memory press d tune to frequency press a for tones f plus 1 press f plus c for 1 second for tone press f plus 8 for transmit reess star rotate tune to set frequency. you can set tones to off for receive subaudible tone frequency press star twice rotate tune for ddsired frequency then press push to talk which returns to memory display
