Precautions
•
•
•
•
•
•
•
•
•
•
•
Do not charge the transceiver and battery pack when they are wet.
Ensure that there are no metallic items located between the
transceiver and the battery pack.
Do not use options not specified by kenwood.
If the die-cast chassis or other transceiver part is damaged, do not
touch the damaged parts.
If a headset or headphone is connected to the transceiver, reduce
the transceiver volume.  Pay attention to the volume level when
turning the squelch off.
Do not place the microphone cable around your neck while near
machinery that may catch the cable.
Do not place the transceiver on unstable surfaces.
Ensure that the end of the antenna does not touch your eyes.
When the transceiver is used for transmission for many hours, the
radiator and chassis will become hot.  Do not touch these locations
when replacing the battery pack.
Do not immerse the transceiver in water.
Always switch the transceiver power off before installing optional
accessories.
Turn the transceiver power off in the following locations:
• In explosive atmospheres (inflammable gas, dust particles,
metallic powders, grain powders, etc.).
• While taking on fuel or while parked at gasoline service stations.
• Near explosives or blasting sites.
• In aircrafts. (Any use of the transceiver must follow the
instructions and regulations provided by the airline crew.)
• Where restrictions or warnings are posted regarding the use of
radio devices, including but not limited to medical facilities.
• Near persons using pacemakers.
•
•
•
•
•
•
•
•
Do not disassemble or modify the transceiver for any reason.
Do not place the transceiver on or near airbag equipment while
the vehicle is running.  When the airbag inflates, the transceiver
may be ejected and strike the driver or passengers.
Do not transmit while touching the antenna terminal or if
any metallic parts are exposed from the antenna covering.  
Transmitting at such a time may result in a high-frequency burn.
If an abnormal odor or smoke is detected coming from the
transceiver, switch the transceiver power off immediately,
remove the battery pack from the transceiver, and contact your
Kenwood dealer.
Use of the transceiver while you are driving may be against
traffic laws.  Please check and observe the vehicle regulations
in your area.
Do not expose the transceiver to extremely hot or cold
conditions.
Do not carry the battery pack (or battery case) with metal
objects, as they may short the battery terminals.
When operating the transceiver in areas where the air is dry, it
is easy to build up an electric charge (static electricity).  When
using a earphone accessory in such conditions, it is possible for
the transceiver to send an electric shock through the earphone
and to your ear.  We recommend you use only a speaker/
microphone in these conditions, to avoid electric shocks.

battery pack.
Match the guides of the battery pack with the corresponding
grooves on the upper rear of the transceiver, then firmly press
the battery case to lock it in place.
Flip the safety catch into place to prevent accidentally pressing
the release latch and removing the battery pack.
To remove the battery pack, lift the safety catch, then press the
release latch to unlock the battery pack. Lift the battery pack
away from the transceiver.
Installing Alkaline Batteries
To open the optional BT-14 battery case lid, insert your thumb or
finger into the hole on the top of the battery case, then pull the
cover up.
Insert (or remove) six AA (LR6) Alkaline batteries.
• Be sure to match the battery polarities with those marked in
the bottom of the battery case.
Align the two tabs at the bottom of battery case, then close the
cover until the locking tabs on top click.
To install the battery case onto (or remove it from) the
transceiver, follow steps 1 to 3 of “Installing the Optional PB43N Ni-MH Battery Pack”.
Note:
◆ Do not use Manganese batteries or Ni-Cd batteries in place of
Alkaline batteries.
◆ Always replace all batteries at the same time. Mixing old and new
batteries or mixing types (such as Alkaline with zinc carbon) will
reduce overall performance and could cause leakage or rupture.
◆ Remove all batteries from the case when it is not expected to be in
use for several months.
◆ The voltage of new Alkaline batteries varies slightly, depending on
the manufacturer. Thus, the high battery power indicator may not
appear even though new Alkaline batteries are installed {page 54}.
◆ To lift the battery pack safety catch, use a piece of hardened
plastic or metal, such as a screwdriver, that is no more than 6 mm
wide and 1 mm thick. It is imperative that you place the implement
under only the lip of the safety catch so that you do not damage the
release latch.
Installing the Antenna
Screw the antenna into the connector on the top of the transceiver
by holding the antenna at its base and turning it clockwise until
secure.
Note: The antenna is neither a handle, a key ring retainer, nor a
speaker/ microphone attachment point. Using the antenna in these
ways may damage the antenna and degrade your transceiver’s
performance.

1 Press [F].
• The MHz digit blinks.
2 Rotate the Selector (or press [UP]/ [DOWN]) to select the
desired MHz value.
3 After selecting the desired MHz value, Press any key other
than [ ] to exit the MHz Tuning Mode and return to normal
VFO Mode.
4 Continue adjusting the frequency as necessary, using the
Selector (or press [UP]/ [DOWN]) keys).
12
Direct Frequency Entry
In addition to rotating the Selector (or pressing [UP]/ [DOWN]),
there is another way to select the frequency. When the desired
frequency is far away from the current frequency, you can directly
enter a frequency using the numeric keypad.
1 Press [VFO].
• You must be in the VFO Mode to make the direct frequency
entry.
2 Press [#].
Press the numeric keys ([0] to [9]) to enter your desired
frequency. [ ] allows you to complete the MHz digits entry.
• Pressing [#] fills all remaining digits (the digits you did not
enter) with 0 and completes the entry. For example, to
select 145.000 MHz, press [1], [4], and [5], then press [#] to
complete the entry.
• If you want to revise the MHz digits only, leaving the kHz
digits as they are, press [VFO] in place of [#].
Note:
◆ If the entered frequency does not match the current frequency
step size, the frequency is automatically rounded down to the next
available frequency.

OPERATING THROUGH REPEATERS
Repeaters are often installed and maintained by radio clubs,
sometimes with the cooperation of local businesses involved in the
communications industry. Compared to simplex communication,
you can usually transmit over much greater distances by using a
repeater. Repeaters are typically located on mountain tops or other
elevated locations. They generally operate at higher ERP (Effective
Radiated Power) than a typical station. This combination of
elevation and high ERP allows communications over considerable
distances.
TX: 144.725 MHz
TX tone: 88.5 Hz
RX: 145.325 MHz
TX: 144.725 MHz
TX tone: 88.5 Hz
RX: 145.325 MHz
18
Repeater Access
Most repeaters use a receive and transmit frequency pair with
a standard or non-standard offset (odd-split). In addition, some
repeaters must receive a tone from the transceiver in order to gain
access to the repeater. For details, consult your local repeater
reference.
■ Selecting an Offset Direction
The offset direction allows your transmit frequency to be higher (+)

Operation Notices
The transceiver has been designed and engineered to avoid
possible hardware glitches. However, you may notice the following
symptoms when you operate the transceiver. These symptoms are
not malfunctions.
Receiving Signals in Cities
When you receive signals in cities, the receiver’s entire antenna
indicator may light up without receiving any strong signals. This
happens when the RF amplifier in the receiver is overloaded by
strong interference signals that are nearby.
Transmission
If you continuously transmit for more than 8 minutes at high power (5
W), the transceiver becomes warm.
If you continue or repeat the transmission before the transceiver
cools down, the thermal protector gradually decreases the output
power down to 1.5 W.
Internal Beats
On some spots of the frequency, the antenna indicator moves
without receiving any signals or you cannot receive any signals.
This is inevitable when you use super-heterodyne receivers. If this
happens, access Menu No. 17 (BS) and select “ON”.
Internal Beats Frequency
140.800 MHz, 153.600 MHz, 166.400 MHz, 168.350 MHz

TROUBLESHOOTING
The problems described in this table are commonly encountered
operational malfunctions and are usually not caused by circuit
failure.
Problem
Nothing appears on the display
when the transceiver is switched
ON, or the display is blinking ON
and OFF.
Most keys and the Selector do
not function.
You cannot recall any memory
channel.
You cannot select the exact
desired frequency using the
selector.
Increasing the Volume control
does not allow you to hear audio.

Display Mode. Press [PTT] +
[MR] + Power ON to exit Channel
Display Mode.
You have stored no data in any of
the memory channels. Store the
desired frequencies in the memory
channels.
The current frequency step size
does not allow the frequency to be
selected. Select an appropriate
frequency step size. Press [F], [3]
to change the frequency step size.
Programmable VFO frequency
range is too narrow. Expand the
frequency range in Menu No. 1
(P.VFO).

or DCS) is ON. Turn OFF the
selective call function.
Problem
Solution
You selected a frequency outside
the allowable range. Select a
frequency within the
allowable transmit frequency
range.
You cannot transmit by pressing
[PTT].
You selected a transmit offset
that places the transmit frequency
outside the limit. Select a proper
offset direction or offset frequency.
TX inhibit is ON. Access Menu
No.14 (TXI) and select “OFF”.
The battery pack voltage is too low
to transmit. Change or replace
the battery.
