Please observe the following precautions to prevent fire, personal injury, and
transceiver damage:

When operating mobile, do not attempt to configure your transceiver while
driving because it is simply too dangerous.* be aware of local laws
pertaining to the use of headphones/headsets while driving on public roads.
If in doubt, do not wear headphones while mobiling.

Do not transmit with high output power for extended periods. The
transceiver may overheat.* do not modify this transceiver unless instructed
by this manual or by kenwood documentation.

Do not expose the transceiver to long periods of direct sunlight nor place the
transceiver close to heating appliances.

Do not place the transceiver in excessively dusty areas, humid areas, wet
areas, nor on unstable surfaces.

If an abnormal odor or smoke is detected coming from the transceiver, turn
off the power immediately. Contact a kenwood service station or your
dealer. The transceiver is designed for a 13.8 v power source. Never use a
24 v battery to power the transceiver. 

#1 PREPARATION FOR MOBILE AND FIXED STATION OPERATION

#1.1 Mobile installation

Install the transceiver in a safe, convenient position inside your vehicle that
minimizes danger to your passengers and yourself while the vehicle is in
motion. For example, consider installing the transceiver under the dash in
front of the passenger seat so that knees or legs will not strike the radio
during sudden braking of your vehicle. Try to pick a well-ventilated location
that is shielded from direct sunlight.

Installation example

Use the supplied mounting bracket to install the transceiver inside your
vehicle. To enjoy the best viewing angle, you can position the transceiver in
the bracket in a number of ways as shown below.

Installation steps;

I Install the mounting bracket in the vehicle using the supplied flat washers
and self-tapping screws. There are 4 washers and 4 screws supplied. The
bracket can be mounted with the bracket opening for the transceiver facing
down for under dash mounting, or with the opening facing up. The bracket
must be installed so that the 4 screw holes on the edge of each bracket side
are facing forward.

2 Position the transceiver, then insert and tighten the supplied hexagon
sems screws and washers. There are 2 screws and 2 washers supplied for
each side of the bracket. Double check that all hardware is tightened to
prevent vehicle vibration from loosening the bracket or transceiver.

#1.2 Dc power cable connection

Mobile operation

The vehicle battery must have a nominal rating of 12 v. Never connect the
transceiver to a 24 v battery. Be sure to use a 12 v vehicle battery that has
sufficient current capacity. It the current to the transceiver is insufficient, the
display may darken during transmission, or transmit output power may drop
excessively.

1 Route the dc power cable supplied with the transceiver directly to the
vehicle's battery terminals using the shortest path from the transceiver'.

If using a noise filter, it should be installed with an insulator to prevent it from
touching metal on the vehicle.

It is not recommended to use the cigarette lighter socket since some
cigarette lighter sockets introduce an unacceptable voltage drop.

It the power cable must be routed through a hole in the vehicle chassis or
body, for example in the firewall at the front of the passenger compartment,
use a rubber grommet to protect the cable from abrasion, Dismantle the
fuse holder to pass the cable through the firewall.

The entire length of the cable must be dressed so it is isolated from heat
and moisture.

2 After the cable is in place, wind heat-resistant tape around the fuse holder
to protect it from moisture. Tie down the full run of cable.

3 To prevent the risk of short circuits, disconnect other wiring from the
negative h battery terminal before connecting the transceiver.

4 Confirm the correct polarity of the connections, and attach the power cable
to the battery terminals; red connects to the positive (+) terminal, black
connects to the negative (-) terminal.

Use the full length of the cable without cutting off excess even if the cable is
longer than required, in particular, never remove the fuse holders from the
cable.

5 Reconnect any wiring removed from the negative terminal.

6 Connect the dc power cable to the transceiver's power supply connector.
Press the connectors firmly together until the locking tab clicks. Fixed station
operation

In order to use this transceiver for fixed station operation, you will need a
separate 13.8 v do power supply that must be purchased separately. The
recommended current capacity of your power supply is 12 a.

1 Connect the dc power cable to the regulated dc. power supply and check
that polarities are correct(Red: positive, black: negative). Do not directly
connect the transceiver to an Ac outlet! Use the supplied dc power cable to
connect the transceiver to a regulated power supply. Do not substitute a
cable with smaller gauge wires.

2 Connect the transceiver's dc power connector to the connector on the dc
poinder cable. Press the connectors firmly together until the locking tab
clicks. 

Note; For your transceiver to fully exhibit its performance capabilities, the
following optional power supply is recommended: Ps -33 (20. 5 a, 25% duty
cycle. Before connecting the dc power supply to the transceiver, be sure to
switch the transceiver and the dc power supply off Do not plug the dc power
supply in to an ac outlet until you make all connections. 

Replacing fuses

If the fuse blows, determine. the cause then correct the problem, after the
problem is resolved, then replace the fuse. If newly installed fuses continue
to blow, disconnect the power cable and contact your dealer or the nearest
service center for assistance.

Fuse in Transceiver 15a

Supplied accessory Dc power cable 20A

Caution Only use fuses of this specified type and Rating.

Note: If you use the transceiver for long periods when the ve hicie battery is
not fully charged, or when the engines is off the battery may become
discharged, and will not have sufficient reserves to start the vehicle, avoid
using the transceiver under these conditions.

#1.3 Antenna connection

Before operating, you must first install an efficient, well-tuned antenna. The
success of your installation will depend largely on the type of antenna and
its correct installation. The transceiver can give excellent results if the
antenna system and its installation is given careful attention.

Your choice of antenna should have a 50 ohm impedance to match the
transceiver input impedance. Use low-loss coaxial feed line that also has a
characteristic impedance of 50ohms. Coupling the antenna to the
transceiver via feedlines having an impedance other than 50 q reduces the
efficiency of the antenna system, and can cause interference to nearby
broadcast television receivers, radio receivers, and other electronic
equipment.

Caution.

Transmitting with out first connecting an antenna Or other matched load
may damage the transceiver, Always connect the antenna to the transceiver
Before transmitting. All fixed stations should be equipped with a Lightning
arrester to reduce the risk of fire, Electric shock, and transceiver damage, 

#1.4 Accessory connections

External speakers

If you plan to use external speakers, choose speakers with an impedance of
8 ohms. The external speaker jacks accept a @.5 mm (1/8") diameter mono
(2-conductor)plug. Recommended speakers include the sp-sob and Sp-41.

Microphone

To communicate in the voice modes, plug a 600 ohm microphone equipped
with an 8-pin modular connector in to the modular socket on the front panel
of the transceiver. Press firmly on the plug until the locking tab clicks.

#1.5 Packet equipment connections

if you intend to use this transceiver for packet operation you will need the
following equipment Personal computer with communications software
Terminal node controller (tnc) Tnc power supply Rs-232c cable 6-pin mini
din plug (optional pg-5a)

For the data connector pins, refer to "packet Operation".

Note:  Do not share a single power supply between the transceiver and the
TNC Keep a wide separation between the transceiver and computer as
practical to reduce noise-pickup by the transceiver  One end of the optional
PG-5A cable has no connector.  Attach the appropriate connector that
mates with the TNC.

#4 OPERATING BASICS

#4.1 Switching power on/off

1 Switch on the dc power supply. If operating mobile, skip this step.

2 Press the power switch to switch on the transceiver.

3 To switch off the transceiver, press the power switch again. In a fixed
installation, after the transceiver has been switched on, it can then be
switched off or on by using only the power switch on the dc power supply.

#4.2 Adjusting Volume

Turn the vol control clockwise to increase the audio level and
counterclockwise to decrease the audio level.

#4.3 Adjusting Squelch

The purpose of squelch is to silence audio output from the speaker when no
signals are present. When squelch is set correctly, you will hear sound only
while a station is actually being received. The point at which ambient noise
on a frequency just disappears, called the squelch threshold, depends on
the frequency.

Turn the sol control clockwise to just eliminate the background noise when
no signal is present.

#4.4 Selecting a Band

Press band selectto select the v.h.f or u.h.f band. PTT appears above the
v.h.f or u.h.f frequency to sho which band you selected.

#4.5 Selecting Frequencies

Tuning control

Using the tuning control is convenient when you are with in easy reach of
the transceiver front panel, and the frequencies to be selected lie near the
current frequency.

1 Press VFO to select VFO mode.

2 Turn the tuning control to select a receive frequency.  Clockwise rotation
increases the frequency one frequency stop at a time. Counterclockwise
rotation decreases the frequency one step at a time.  To change frequencies
in steps of 1 mhz, press MHz first. Pressing mhz again cancels the 1 MHz
function.  To change in steps of 10 MHz, press F and Mhz first. Pressing F
cancels the 1 0 MHz function. If you cannot select a particular receive
frequency, the frequency step size needs to be changed. See"Changing
frequency step size" for further information.  You can also select frequencies
via the microphone keypad. See "keypad direct Entry".

Microphone Up an Down buttons

Using mic up or down for frequency selection is useful when mobiling or any
time you are mot immediately inn front of the transceiver.

Press up or down once to change the receive frequency by one frequency
step in the direction indicated by the button.

Pressing and holding either button causes the frequency@to step
repeatedly in one direction until the button is released.

To change frequencies in steps of 1 mhz (or 10 mhz),press [mhz] (or [1-7 +
[mhz]) first.

#4.6 Transmitting

I When ready to begin transmitting, press and hold mic(Ptt] and speak in a
normal tone of voice. "On air" and the rf power meter appear.

Speaking too close to the microphone, or too loudly, may increase distortion
and reduce intelligibility of your signal at the receiving station.

The rf power meter shows the relative transmit output power.

2 When you finish speaking, release mic PTT

Selecting output power

It's wise, and required by law, to select the lowest power that allows reliable
communication. If operating from battery power, lower transmit power will
give you more operating time before a charge is necessary. Reducing power
lowers the risk of interfering with others on the band.

Press Loww to select the transmit power you require.

Each time you press Low, the transmit power is changed from high to
medium to low, then back to high again. The display shows nothing for high
power, an M for medium and an L for low power.

Caution. Do not transmit with high output power for Extended periods. The
transceiver may overheat and malfunction. Continuous transmissions cause
the radiator to Overheat never touch the radio or in such a situation.

Note: when the transmitter overheats because of ambient high temperature
or continuous transmissions, the protective circuit function to lower transmit
output power.

#5 MENU SET[UP

#6 OPERATING THROUGH REPEATERS

Compared to simplex communication, you can usually transmit over much
greater distances by using a repeater Repeaters are typically located on a
mountain top or other elevated location. Often they operate at higher erp(
Effective radiated power) than a typical station. This combination of
elevation and high ERP allows communications over considerable
distances.

Repeaters are often installed and maintained by radio clubs, sometimes with
the cooperation of local businesses involved in the communications
industry. During emergencies, repeater networks can be a valuable aid to
officials responsible for coordinating communications in a community.

#6.1 Repeater access

Most amateur radio voice repeaters use a separate receive and transmit
frequency. The transmit frequency may be higher or lower than the receive
frequency but the difference in frequencies will be a standard amount,
or"standard split". You can set a separate receive and transmit frequency by
selecting the offset frequency and offset direction with respect to the receive
frequency.

In addition, some repeaters may require the transceiver to transmit a tone
before the repeater can be used. To transmit this required tone, activate the
tone function and select a tone frequency. The required tone frequency
depends on the repeater you are accessing.

Flow chart for repeater access

 Selecting offset direction

Select whether the transmit frequency will be higher (+) or lower (-) than the
receive frequency. 

Press [f], [shift].

Each time you repeat this key operation, the offset direction changes from
simplex to + tp - and back to simplex. If the offset transmit frequency falls
outside the allowable transmit frequency range, transmitting is inhibited until
the transmit frequency is brought within the band limits by one of the
following methods:

Move the receive frequency further inside the band.

Change the offset direction.

Note; while using a split memory channel transmission you cannot change
the offset direction

Selecting Offset Frequency

Note: Use numbers 01 to 36 shown in the table above when selecting tone
frequencies via keypad direct entry.

Automatic Repeater Offset

This function automatically selects an appropriate offset direction according
to the frequency that you select on the v.h.f band. The transceiver is
programmed for offset direction as shown below- to obtain an up-to-date
band plan for repeater offset direction, contact your national amateur radio
association.

This complies with the standard arrl band plan. 144.0 to 145.1 simplex 145.1
to 145.5 negative 145.5 to 146.0 simplex 146.0 to 146.4 positive 146.4 to
146.6 simplex 146.6 to 147.0 negative 147.0 to 147.4 positive 147.4 to
147.6 simplex 147.6 to 148.0 negative

Note: automatic repeater offset does not function when reverse or CTCSS is
on. however pressing [recall after automatic repeater after has selected an
offset (split) status. exchanges the receive and transmit frequencies.

3 Select menu no. 5 (repeater).

4 Press right arrow, then select item no. 1 (auto offset, the default).

5 Press set to toggle the function on (default) or Off,

6 Press menu again to exit menu mode.

#6.2 Reverse Function

When used while monitoring a repeater, the reverse function allows you to
manually check the signal strength of a station accessing the repeater. If the
station's signal is strong, it is best to move to a simplex frequency to
continue the contact and free up the repeater.

Press reverse to toggle the reverse function on or off. The receive frequency
and the transmit frequency are exchanged, R appears on the display when
the function is on.

Note: 
By pressing reverse places the transmit frequency outside the allowable
trans"t frequency range, an error beep sounds when PTT is pressed, and
transmission is inhibited. 
If reverse would place the receive frequency outside the receive frequency
range, an error beep sounds when reverse is pressed. No reversal occurs.
Automatic repeater offset does not function while reverse is on. 
You cannot switch reverse on or off while transmitting.

Automatic Simplex Checker (asc)

This function automatically monitors the strength of the signal you a re
receiving from the repeater. If the signal strength is high enough to allow
direct contact without a repeater, an indicator on the display begins blinking.
This alerts you to move off to a private frequency and release the repeater
for other users.

I Hold rev for 1 s to switch the function on. The asc indicator appears. While
direct contact is possible, the asc indicator banks.

2 To cancel asc, press rev. Note: When direct contact becomes impossible,
the asc indicator stops blinking. Asc does not function if your transmit and
receive frequencies are the same (simplex operation). ASC does not
function while scanning. If you recall a memory channel or the call channel
that contains that contains reverse on status, ASC is switched off.

#7 MEMORY CHANNELS

in memory channels, you can store frequencies and related data that you
often use. A total of 280 memory channels are available, 140 each for v.h.f
and u.h.f

You can also store a name for each memory channel. Using this naming
function restricts the total number of memory channels to 180, but allows
you to select the ratio of channels between the v.h.f and u.h.f bands, from
among 5 types. For more information, see "naming memory channels".

#7.1 Simplex or split memory channel?

There are 2 methods of storing transmit/receive frequencies and related
data in memory channels, depending on the relationship of the transmit and
receive frequencies. You can use each memory channel either as a simplex
channel or spit channel. Use as a split channel to store a separate receive
and transmit frequency.

Simplex memory channels: Rx frequency = tx frequency Split memory
channels: Rx frequency does not equal tx frequency

Note. Not only can you store data in memory channels. but you can also
upgrade existing data with new data.

The data listed below can be stored in each memory channel: Rx frequency
Tx frequency Tone frequency CTCSS frequency Tone or CTCSS status
Frequency step Offset direction Reverse status DTSS code, DTSS status
Memory channel lockout Memory channel name 

#7.2 VHF and UHFMemory Channel Ratio

You can change the ratio of memory channels between the V.h.f and u.h.f
bands, from the factory default (90 channel search). Changing the ratio
requires all memory channels to be cleared. So decide the appropriate ratio
before storing data in memory channels.

The selectable ratios are as shown below: 90 and 90 in each 70 in one and
110 in the other 50 in one and 130 in the other 140 in each without memory
channel names

by repeat steps I to 10. The stored names also are erased by clearing
memory channels.

#7.8 Call Channel

The call channel can be used to store any frequency and related data that
you will recall often. The call channel can be programmed with a simplex or
split frequency as well as related data that can be stored in the memory
channels. No matter what mode the transceiver is in, the call channel can
always be selected quickly. You may want to dedicate the call channel as an
emergency channel within your group. In this case, the call f0 scan will be
useful.

The default frequency stored in the call channel are 144 and 440 Mhz.

The contents of the call channel cannot be deleted; however, you can
overwrite old data with new data as described in the next section.

Recalling the Call Channel

is not transferred to the VFO. To transfer a transmit frequency, press
reverse, then press F, then press VFO.

#7.10 Channel Display Function

When this function is switched on, the transceiver displays only memory
channel numbers instead of frequencies.

Hold LOW and press power on to toggle this function on or Off.

#7.11 Initializing Memory - Resetting

If your transceiver seems to be malfunctioning, initializing may resolve the
problem

Remember that initializing the memory channels requires that you r"nter
memory channel data again after initialization. On the other hand,
initialization is a quick way to erase all data from all channels.

Note: While using the channel display or all lock function you cannot do
partial reset nor full reset.

Defaults contents are 144 Mhz, 5 Mhz step and 88.5 Hz for V.h.f and 440
MHZ, 25 Mhz step and 88.5 Hz for U.h.f.

(All reset Press Memory recall) To quit resetting, press any key other than
memory recall.

2 Press memory recall again.

Note. You can also do partial reset or full reset by pushing the reset switch
on the transceiver

#8 PROGRAMMABLE MEMORY (PM)

Programmable Memory (pm) allows you to store virtually all settings
currently set on the transceiver. So you can quickly recall exactly the same
environment later. This transceiver provides 4 pm channels. If you are the
type who likes the many features offered by modern transceivers, but
dislikes remembering how to make all the necessary settings, you will find
programmable memory particularly useful.

#8.1 Programmable Information

The following programmable settings are shared by the V.h.f and U.h.f
bands: Tx band Automatic power off Time-out timer Auto dimmer change
Positive/ negative reversal Transfer rate Control band Automatic band
change Display dimmer Display contrast Beep volume DTSS/page code
transmit delay Microphone key confirmation tone

The following settings can be separately stored for the V.h.f and U.h.f
bands:

VFO frequency Memory recall mode Tx band Frequency step Tone
frequency Tone status Offset direction Automatic repeater offset Upper
frequency limit (for programmable VFO) Scan resume method Automatic
simplex checker DTSS/page status Page code memory channels VFO
mode Call channel mode Control band Transmit output power CTCSS
frequency CTCSS status Offset status Reverse status Lower frequency limit
(for programmable VFO) Programmable Memory (pm) S-meter squelch
Advanced intercept point DTSS code Dual band RX

#8.2 Application Examples

The following are examples of how you might use Programmable memory.
These examples may not represent applications useful to you, but you will
understand the flexibility of this function.

Situation 1

You share your transceiver with other members in your family or club.
However, each individual has personal preferences for how they like to set
various functions. You have to keep changing many settings each ti" you
use the transceiver,

Solution:

Because 4 pm channels are available, up to 4 persons can separately
program the transceiver and store their customized environment. Then each
person can quickly change to his or her favorite settings, simply by recalling
a PM channel.

It is too much trouble to change the settings after somebody else has
reconfigured them. So this application may avoid having a feature-rich
transceiver but never using many useful features.

Situation 2

While operating mobile on the way to work every morning, you prefer a
silent transceiver that does not interrupt the morning calm. In addition, you
feel that a bright display is a waste of electricity in sunlight.

At night when driving home, you realize the beep function truly serves a
purpose and you acknowledge it is nice to see a bright display after dark.

Solution:

In two pm channels, store the same operating data such as frequency,
offset, DTSS code, etc., and store different settings for the display dimmer
and beep functions. Then you can quickly recall the best settings for day or
night operating.

Situation 3

You cannot figure out how you can make the transceiver exit the current
mode.

Solution

Simply recall pm channel 1 that contains an exact copy of it he transceiver
default environment. You will not lose the contents any memory channels.

#8.3 Storing Data in PM Channels

1 Confirm that the following conditions have been satisfied: Both bands are
in the receive mode. Scan is not being used on either band, Microphone
control is off

2 Select the desired band.

3 Select the desired frequency and related data(Tone, CTCSS, DTSS, etc.)
using VFO mode.

4 If required, select another band, then select the desired frequency and
related data.

5 Press f then PM

The pm channel numbers appear and blink.

#9 SCAN

Scan is a useful feature for hand off monitoring of favourite frequencies.
After becoming comfortable with how to use all types of scan, the monitoring
flexibility gained will increase your operating efficiency. 0

This transceiver provides the following conventional scans in addition to
"visual scan" that may be new to you. 

VFO scan All frequencies tunable on the band Memory scan F Frequencies
stored in the memory channels Program scan All frequencies in the range
selected on the band Mhz scan All frequencies within 1 MHZ range Call vf0
scan Call channel plus the current VFO frequency Call memory scan Call
channel plus the memory channel last used

When Using With CTCSS and DTSS

While using CTCSS, scan stops and the squelch opens only when received
signals contain the matching CTCSS tone,

While using DTSS, scan stops for any signals received However, if the
signals do not contain the matching DTSS code, the squelch does no( open.

When both CTCSS and DTSS are on, scan stops for signals that contain
the matching CTCSS tone. However it the signals do not contain the
matching DTSS code, the squelch does not open.

Note: 
Remember to adjust the squelch threshold level before using scan. 
Always turn off monitor and page before using scan. 
When using s-meter squelch, scan stops when the received signal strength
matches or exceeds the s-meter setting. Scan resumes 2 seconds after the
signal level drops below the s-meter setting.

#9.1 Visual Scan

While you are on the air, visual scan allows you to monitor frequencies near
the current operating frequency. Visual Scan graphically and simultaneously
shows how all frequencies in the selected range are busy. You will see up to
14 segments, for each channel, that represent 7 s-meter levels (2 segments
per level).

You determine the scan range by selecting the center frequency and the
number of channels. The default number of channels is 49.

Depending on conditions, visual scan and the conventional s-meter may
indicate different signal strength levels.

#9.2 Scan Resume Methods

Before using scans other than visual scan, it's necessary to decide under
what condition you want your transceiver to continue scanning after
detecting and stopping for a signal. You can choose time-operated mode or
Carrier-operated mode. The default is time-operated mode.

Time-operated Mode

Your transceiver slops scanning after detecting a signal, remains there for
approximately 5 seconds, and then continues to scan ever if the signal is
still present.

Carrier-operated Made

Your transceiver stops scanning after detecting a signal and remains on the
same frequency until the signal drops out. There is a 2 second delay
between signal drop-out and scan resumption to allow time for any
responding stations to begin transmitting.

Note: 
Turing the tuning control clockwise, or pressing mic up after a signal that
has stopped scan drops out, causes scanning to resume immediately
upward. 
Tuning the tuning control counter clock wise, or pressing mic down after a
signal that has stopped scan drops out, causes scanning to resume
immediately downward.

4 When you are called: The squelch of your transceiver opens only, when
the selected tone is received. When you make a call. Press and hold mic
PTT.

Note.,
 You can select a separate tone frequency for the gtcss and tone functions.
When using DTSS or page with CTCSS, the squelch opens only if the
correct tone is received and the received DTSS code or page code matches
the code stored in your transceiver 
If you select a high tone frequency, receiving audio or noise that contains
the same frequency portions may cause CTCSS to function incorrectly. 
To prevent noise from causing this problem, select an appropriate noise
squelch level using the squelch control.

Automatic Tone Frequency ID

This function automatically identifies the incoming tone frequency on a
received signal.

1 Hold tone for 1 second to activate the function- A tone frequency display
replaces the frequency display and the 1 hz decimal begins blinking. When
a signal is received, the transceiver beginsscanning through all tons
