UHF DIGITAL TRANSCEIVER
B5A-0037-10 (E,T)
INSTRUCTION MANUAL

THANK YOU
We are grateful you have chosen KENWOOD for your
dPMR446 applications.
OPERATING CONDITIONS
Open locations (no obstructions) : Up to 9.0 km
Note:
◆The above range is based on field testing and may vary with your
operating conditions and individual transceiver.
◆
Digital technology provides superior clarity in extended coverage.
As RF signal strength weakens with distance, analog reception
becomes increasingly noisy and intermittent. dPMR's low BER
improves reception in fringe areas, thereby “effectively” increasing
coverage as much as twenty percent over analog.

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

iii
• 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.
• Danger of explosion if the battery is incorrectly replaced; replace
only with the same type.
• When attaching a commercial strap to the transceiver, ensure
that the strap is durable. In addition, do not swing the transceiver
around by the strap; you may inadvertently strike and injure
another person with the transceiver.
• If a commercially available neck strap is used, take care not to let
the strap get caught on nearby machine.
• 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-necklaces 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.
• Avoid 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.
