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.
•  For safety reasons, we recommend that the AC adapter (for the battery charger) should be 
connected to an easily accessible AC socket.
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 with metal objects, as they may short the battery terminals.
•  Danger of explosion if the battery is incorrectly replaced; replace only with the same type. 
•  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.
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 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.
•  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.
•  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
