preparation
You can operate your transceiver from any of the following
sources:
Rechargeable power pack (supplied with charger)
Six alkaline AA batteries (using the supplied alkaline pack)
Vehicle battery power (using optional adapter)
OPERATING FROM THE RECHARGEABLE POWER PACK
You can use the supplied rechargeable power pack to power
your transceiver.
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.

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.

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.
You can
override the default subaudible tones for any memory.

SETTING SCAN OPTIONS
Several configuration menu items control how your transceiver
operates
when you scan frequencies or memories. 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.
