Kenwood AD-2820 Instruction Manual

INSTRUCTION MANUALB62‑2418‑30 (E, T)Thank YouWe are grateful you have chosen KENWOOD for your land mobile radio applications.noTices To The user◆ Government law prohibits the operation of unlicensed radio transmitters within the territories undergovernment control.◆ Illegal operation is punishable by fine and/or imprisonment.◆ Refer service to qualified technicians only.Safety: It is important that the operator is aware of, and understands, hazards common to theoperation of any transceiver.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. Payattention to the volume level when turning the squelch off.• Do not place the microphone cable around your neck while near machinery that may catch thecable.• 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 becomehot. 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 beconnected 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 theairline crew.)• Where restrictions or warnings are posted regarding the use of radio devices, including but notlimited 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 theairbag 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 theantenna 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 poweroff 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 observethe 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 a earphone accessory in such conditions, it is possible for thetransceiver to send an electric shock through the earphone and to your ear. We recommend youuse 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 causethe battery to rupture producing flames or extreme heat, deteriorate, or cause other forms ofdamage 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 seriousdamage, 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 orstore 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 orsmoke, 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 isignited, 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 over80°C)!If the polymer separator is melted due to high temperature, an internal short‑circuit may occur in theindividual 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, orburst 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 an abnormal chemical reaction may occur. The battery may generate heat or smoke, rupture, orburst into flame.• Use only the specified charger and observe charging requirements!If the battery is charged in unspecified conditions (under high temperature over the regulatedvalue, excessive high voltage or current over regulated value, or with a remodeled charger), it mayovercharge 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 orsmoke, 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 (orvoltage), 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 maygenerate 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, anunexpected large amount of current may flow upon discharging. The battery may generate heat orsmoke, 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 connectwith a charger or operating equipment, do not force it; check the polarity of the battery. If the batterypack is reverse-connected to the charger, it will be reverse-charged and an abnormal chemicalreaction 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 soonas possible, without rubbing your eyes. Go to the hospital immediately. If left untreated, it may causeeye‑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. Thebattery 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 flammableareas. Electrolyte leaking from battery can easily catch on fire and may cause the battery togenerate 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 seemsabnormal 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.Firmware CopyrightsThe title to and ownership of copyrights for firmware embedded in KENWOOD product memories arereserved for JVCKENWOOD Corporation.Information on Disposal of Old Electrical and Electronic Equipment and Batteries (applicable for countriesthat have adopted separate waste collection systems)Products and batteries with the symbol (crossed-out wheeled bin) cannot be disposed as householdwaste.Old electrical and electronic equipment and batteries should be recycled at a facility capable ofhandling these items and their waste byproducts.Contact your local authority for details in locating a recycle facility nearest to you.Proper recycling and waste disposal will help conserve resources whilst preventing detrimental effectson our health and the environment.Notice: The sign “Pb” below the symbol for batteries indicates that this battery contains lead.NOTIFICATIONThis equipment complies with the essential requirements of Directive 2014/53/EU.RestrictionsThis equipment requires a licence and is intended for use in the countries as below.AT BE DK FI FR DE GR IS IE IT LILU NL NO PT ES SE CH GB CY CZ EEHU LV LT MT PL SK SI BG RO HR TRISO3166VHF FM TRANSCEIVERTK‑2000UHF FM TRANSCEIVERTK‑3000© 2019Model Frequency range Max. output powerTK-2000-E TX/RX 136.000 - 174.000 MHz 5 WTK-2000-T TX/RX 136.000 - 174.000 MHz 5 WTK-3000-E TX/RX 440.000 - 470.000 MHz 4 WTK-3000-T TX/RX 440.000 - 470.000 MHz 4 W
