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.

•For safety reasons, we recommend that the AC adapter (for the battery charger) should be connected to an easily accessible AC socket.

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 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 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 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. 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-necklace 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.

vii

•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 odour, 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.
