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 speciﬁ ed 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.

Turn the transceiver power off in the following locations:

• In explosive atmospheres (inﬂ ammable 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 inﬂ ates, 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 trafﬁ c 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 ﬂ ammable objects such as organic solvent. Mishandling may cause the battery to rupture producing ﬂ 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 ﬂ 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 ﬂ ow and the battery may generate heat or smoke, rupture, or burst into ﬂ 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 ﬂ ame.

• Do not leave the battery near ﬁ 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 ﬂ 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 ﬂ ame.

• Do not charge the battery near ﬁ 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 ﬂ ame.

• Use only the speciﬁ ed charger and observe charging

requirements!

If the battery is charged in unspeciﬁ ed 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 ﬂ 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 ﬂ 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 ﬂ 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 ﬂ 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

ﬂ 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 ﬂ 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 ﬂ ow upon discharging. The battery may generate heat or smoke, rupture, or burst into ﬂ 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 reversecharged and an abnormal chemical reaction may occur. The battery may generate heat or smoke, rupture, or burst into ﬂ 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 speciﬁ ed time!

If the battery pack has not ﬁ nished charging even after the

regulated time has passed, stop it. The battery may generate heat or smoke, rupture, or burst into ﬂ 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

ﬂ ame.

• Keep ruptured and leaking battery packs away from ﬁ re!

If the battery pack is leaking (or the battery emits a bad odor),

immediately remove it from ﬂ ammable areas. Electrolyte leaking from battery can easily catch on ﬁ re and may cause the battery to generate smoke or burst into ﬂ 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 ﬂ ame.
