Safety: It is important that the operator is aware of, and
understands, hazards common to the operation of any
transceiver.
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.
ii
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.

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.

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 (+)
or lower (–) than the receive frequency.
1 Press [F], [8] to select an offset direction.
• Continually press [F], [8] to toggle the functions as follows:
“+” >> “–” >> OFF.
2 Press any key other than the Selector (or [UP]/ [DOWN]) to
store the setting.
• The “ ” or “ ” icon appears above the frequency,
indicating which offset direction is selected.
If the offset transmission frequency falls outside the allowable
range, transmission is inhibited. In this case, adjust the
reception frequency so that the transmission frequency is
within the band limits.
Note: While using an odd-split memory channel or transmitting,
you cannot change the offset direction.
20
■ Selecting an Offset Frequency
To access a repeater which requires an odd-split frequency pair,
change the offset frequency from the default which is used by

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

desired frequency using the
selector.
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).
Increasing the Volume control
does not allow you to hear audio.
The selective call function (CTCSS
or DCS) is ON. Turn OFF the
selective call function.
75
Problem Solution
You cannot transmit by pressing
[PTT].
You selected a frequency outside
the allowable range. Select a
frequency within the
allowable transmit frequency
range.
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.

No. 23 (DT.L) and select “OFF”.
76
Problem Solution
The transceiver switches OFF for
no apparent reason.
The Automatic Power OFF (APO)
function is ON. Access Menu No.
8 (APO) and select your desired
time length or “OFF”.
The transceiver returns to
Reception Mode during a long
transmission.
The transmission time exceeded
the programmed TOT time.
Access Menu No. 12 (TOT) to
select your desired transmission
length. The TOT cannot be turned
OFF, protecting the transceiver
from the thermal damage.
The Scan function does not
resume scanning after the
transceiver detects a signal.
You have selected “SE” (SEEK)
for Menu No. 3 (SCAN). Select
