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.
•Use only KENWOOD specified explosion-protected options for the NX-203 and NX-303 transceivers.
•If the die-cast chassis or other transceiver part is damaged, do not touch the damaged parts.
•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.
•Do not remove the black sheet from the reverse side of the transceiver (refer to the illustration below). Removal of this sheet decreases the waterproof efficiency of the transceiver and may cause malfunctions if water seeps into the transceiver.
•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 change or charge the battery pack in a hazardous location. Charge only in fresh air.
•Danger of explosion if the battery is incorrectly replaced; replace only with the same type.
v
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, 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.
