•

Do not 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 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 an earphone accessory in such conditions, it is possible for the transceiver to send an

electric shock through the earphone and to your ear.

Do not use an earphone/microphone accessory in areas

where static electricity can be easily generated.

•

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.

INSTRUCTION MANUAL

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 the 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 60°C)!

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


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


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.


•

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!


•

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 the 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.
