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.

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.

•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.

•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 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.

•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!

•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 reversecharged 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 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.
