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.
• The charger is the device that disconnects the unit from the AC
mains line. The AC plug should be readily accessible.
iii
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.)

• 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
an 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.
iv
Information concerning the battery pack:
The battery pack includes flammable objects such as organic
solvent. Mishandling may cause the battery to rupture
producing flames or extreme heat, deteriorate, or cause other
forms of damage to the battery. Please observe the following
prohibitive matters.
• Do not disassemble or reconstruct battery!
The battery pack has a safety function and protection circuit to
avoid danger. If they suffer serious damage, the battery may
generate heat or smoke, rupture, or burst into flame.
• Do not short-circuit the battery!
Do not join the + and – terminals using any form of metal (such
as a paper clip or wire). Do not carry or store the battery pack in
containers holding metal objects (such as wires, chain-necklace or
hairpins). If the battery pack is short-circuited, excessive current will
flow and the battery may generate heat or smoke, rupture, or burst
into flame. It will also cause metal objects to heat up.
• Do not incinerate or apply heat to the battery!
If the insulator is melted, the gas release vent or safety function is
damaged, or the electrolyte is ignited, the battery may generate
heat or smoke, rupture, or burst into flame.
• Do not use or leave the battery near fire, stoves, or other heat
generators (areas reaching over 80°C/ 176°F)!
If the polymer separator is melted due to high temperature, an
internal short-circuit may occur in the individual cells and the
battery may generate heat or smoke, rupture, or burst into flame.
• Do not immerse the battery in water or get it wet by other
means!
If the battery’s protection circuit is damaged, the battery may
charge at extreme current (or voltage) and an abnormal chemical
reaction may occur. The battery may generate heat or smoke,
rupture, or burst into flame.
• Do not charge the battery near fire or under direct sunlight!
If the battery’s protection circuit is damaged, the battery may
charge at extreme current (or voltage) and an abnormal chemical
reaction may occur. The battery may generate heat or smoke,
rupture, or burst into flame.
v
• Use only the specified charger and observe charging
requirements!
If the battery is charged in unspecified conditions (under high
temperature over the regulated value, excessive high voltage or
current over regulated value, or with a remodeled charger), it may
overcharge or an abnormal chemical reaction may occur. The
battery may generate heat or smoke, rupture, or burst into flame.
• Do not pierce the battery with any object, strike it with an
instrument, or step on it!
This may break or deform the battery, causing a short-circuit. The
battery may generate heat or smoke, rupture, or burst into flame.
• Do not jar or throw the battery!
An impact may cause the battery to leak, generate heat or smoke,
rupture, and/or burst into flame. If the battery’s protection circuit
is damaged, the battery may charge at an abnormal current (or
voltage), and an abnormal chemical reaction may occur. The
battery may generate heat or smoke, rupture, or burst into flame.
• Do not use the battery pack if it is damaged in any way!
The battery may generate heat or smoke, rupture, or burst into
flame.
• Do not solder directly onto the battery!
If the insulator is melted or the gas release vent or safety function
is damaged, the battery may generate heat or smoke, rupture, or
burst into flame.
• Do not reverse the battery polarity (and terminals)!
When charging a reversed battery, an abnormal chemical reaction
may occur. In some cases, an unexpected large amount of current
may flow upon discharging. The battery may generate heat or
smoke, rupture, or burst into flame.
• Do not reverse-charge or reverse-connect the battery!
The battery pack has positive and negative poles. If the battery
pack does not smoothly connect with a charger or operating
equipment, do not force it; check the polarity of the battery. If the
battery pack is reverse-connected to the charger, it will be reverse-
charged and an abnormal chemical reaction may occur. The
battery may generate heat or smoke, rupture, or burst into flame.
vi
• Do not touch a ruptured and leaking battery!
If the electrolyte liquid from the battery gets into your eyes, wash
your eyes with fresh water as soon as possible, without rubbing
your eyes. Go to the hospital immediately. If left untreated, it may
cause eye-problems.
• Do not charge the battery for longer than the specified time!
If the battery pack has not finished charging even after the
regulated time has passed, stop it. The battery may generate heat
or smoke, rupture, or burst into flame.
• Do not place the battery pack into a microwave or high
pressure container!
The battery may generate heat or smoke, rupture, or burst into
flame.
• Keep ruptured and leaking battery packs away from fire!
If the battery pack is leaking (or the battery emits a bad odor),
immediately remove it from flammable areas. Electrolyte leaking
from battery can easily catch on fire and may cause the battery to
generate smoke or burst into flame.
• Do not use an abnormal battery!
If the battery pack emits a bad odor, appears to have different
coloring, is deformed, or seems abnormal for any other reason,
remove it from the charger or operating equipment and do not use
it. The battery may generate heat or smoke, rupture, or burst into
flame.

Radio FRequency eneRgy SaFety inFoRmation
This Kenwood transceiver has been tested and complies with the standards listed below, in regards
to Radio Frequency (RF) energy and electromagnetic energy (EME) generated by the transceiver.
• FCC RF exposure limits for
Occupational Use Only
. RF Exposure limits adopted by the FCC are generally
based on recommendations from the National Council on Radiation Protection and Measurements, & the
American National Standards Institute.
• FCC OET Bulletin 65 Edition 97-01 Supplement C
• American National Standards Institute (C95.1 – 1992)
• American National Standards Institute (C95.3 – 1992)
This Kenwood transceiver generates RF EME while transmitting. RF EME (Radio Frequency Electric &
Magnetic Energy) has the potential to cause slight thermal, or heating effects to any part of your body less
than the recommended distance from this radio transmitter’s antenna. RF energy exposure is determined
primarily by the distance to and the power of the transmitting device. In general, RF exposure is minimized
when the lowest possible power is used or transmission time is kept to the minimum required for consistent
communications, and the greatest distance possible from the antenna to the body is maintained. The
transceiver has been designed for and is classied for
Occupational Use Only
. Occupational/ controlled
exposure limits are applicable to situations in which persons are exposed to RF energy as a consequence
of their employment, and such persons have been made aware of the potential for exposure and can
exercise control over their exposure. This means you can use the transceiver only if you are aware of
the potential hazards of operating a transceiver and are familiar in ways to minimize these hazards. This
transceiver is not intended for use by the general public in uncontrolled environments. Uncontrolled
environment exposure limits are applicable to situations in which the general public may be exposed to RF
energy, or in which the persons who are exposed as a consequence of their employment may not be fully
aware of the potential for exposure or cannot exercise control over their exposure.
The following list provides you with the information required to ensure that you are aware of RF
exposure and of how to operate this transceiver so that the FCC RF exposure limitations are not
exceeded.
• While transmitting (holding the PTT switch or speaking with VOX enabled), always keep the antenna
and the radio at least 3 cm (1 3/16 inches) from your body or face, as well as from any bystanders. A
LED on the top of the radio shows red when the transmitter is operating in both PTT and VOX modes.
• Do not transmit for more than 50% of the total transceiver use time; transmitting over 50% of the total use
time may exceed the limits in accordance to the FCC RF exposure requirements. Nominal transceiver
operation is 5% transmission time, 5% reception time, and 90% stand-by time.
• Use only the specied antenna for this transceiver; this may be either the antenna provided with the
transceiver or another antenna authorized by Kenwood.
Use only Kenwood authorized accessories (antennas, battery packs, belt clips, Speaker/ Mics or
headsets etc.): When worn on the body, always place the radio in a Kenwood recommended clip or
carrying case meant for this product. The use of other than recommended or approved body- worn
accessories may result in RF exposure levels which exceed the FCC’s occupational/ controlled
environment RF exposure limits.
To ensure that your exposure to RF EME is within the FCC limits for occupational use, you must
observe and adhere to the above points.
Electromagnetic Interference Compatibility
Electronic devices are susceptible to electromagnetic interference (EMI) if they are not adequately
shielded or designed for electromagnetic compatibility. Because this transceiver generates RF
energy, it can cause interference to such equipment.
• Turn OFF your transceiver where signs are posted to do so. Hospitals and health care facilities use
equipment that is sensitive to electromagnetic radiation.
• Turn OFF your transceiver while on board an aircraft when so instructed. Use of the transceiver must
be in accordance with airline regulations and/or crew instructions. B59-2546-00
