ATTENTION:
The RBRC Recycle seal found on KENWOOD lithium-
ion (Li-ion) battery packs indicates KENWOOD’s
voluntary participation in an industry program to collect
and recycle Li-ion batteries after their operating life
has expired. The RBRC program is an alternative to
disposing Li-ion batteries with your regular refuse or in
municipal waste streams, which is illegal in some areas.
For information on Li-ion battery recycling in your area, call (toll free)
1-800-8-BATTERY (1-800-822-8837).

Turn the transceiver power off in the following locations:
• In explosive atmospheres (inammable 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.
• 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 inates, 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 trafc
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
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.

Information concerning the battery pack:
The battery pack includes ammable objects such as organic
solvent. Mishandling may cause the battery to rupture
producing ames 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 ame.
•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
ow and the battery may generate heat or smoke, rupture, or burst
into ame. 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 ame.
•Do not leave the battery near re, 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 ame.
•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 ame.
•Do not charge the battery near re 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 ame.

•Use only the specied charger and observe charging
requirements!
If the battery is charged in unspecied 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 ame.
•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 ame.
•Do not jar or throw the battery!
An impact may cause the battery to leak, generate heat or smoke,
rupture, and/or burst into ame. 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 ame.
•Do not use the battery pack if it is damaged in any way!
The battery may generate heat or smoke, rupture, or burst into
ame.
•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 ame.
•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 ow upon discharging. The battery may generate heat or
smoke, rupture, or burst into ame.
•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 ame.

•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 specied time!
If the battery pack has not nished charging even after the
regulated time has passed, stop it. The battery may generate heat
or smoke, rupture, or burst into ame.
•Do not place the battery pack into a microwave or high
pressure container!
The battery may generate heat or smoke, rupture, or burst into
ame.
•Keep ruptured and leaking battery packs away from re!
If the battery pack is leaking (or the battery emits a bad odor),
immediately remove it from ammable areas. Electrolyte leaking
from battery can easily catch on re and may cause the battery to
generate smoke or burst into ame.
•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
ame.
