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.
• 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:
• 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 wearing pacemakers.
Turn the transceiver power off in the following locations,
unless the model is specifically qualified for such use
(Intrinsically Safe such as approved by Factory Mutual, CSA):
• While taking on fuel or while parked at gasoline service stations.
• The orange seal on the reverse side of the transceiver is
important with respect to the waterproof efficiency of the
transceiver. Do not place stickers or other materials on or
around the seal shown in the figure, or on the reverse side of
the battery pack. Doing so will impair the waterproof efficiency
of the transceiver and may cause it to break down. Additionally,
in order to prevent damage to the seal, do not allow it to come
in contact with foreign materials.
iv
• 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.
v
INFORMATIONCONCERNINGTHEBATTERYPACK
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, chainnecklace 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 fires, 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 immersing the battery in water or getting it wet by
other means!
If the battery becomes wet, wipe it off with a dry towel before
use. 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.
vi
• Do not charge the battery near fires 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 remodelled 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.
• 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.
vii
• 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 out 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.
