• 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

• 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.

3

cover until the locking tabs on top click.

To install the battery case onto (or remove it from) the

4

transceiver, follow steps 1 to 3 of “I
43n n

I-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.

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.

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.

MEMORY CHANNELS

In memory channels, you can store frequencies and related data
that you frequently use so that you do not need to reprogram that
data every time. You can quickly recall a programmed channel
through simple operation. A total of 100 memory channels (50
when using the Memory Name function) are available for storing

frequencies, modes and other operating conditions.

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
