26PreparationPreparing the Battery Pack/External Power SupplyConnecting an External Power Supply for Use in Vehicle(USA/EXP version only)The optional external power supply adapterwith a cigarette lighter plug (SDD-13) allowsthe transceiver to be used in a vehicle.1 Turn off the transceiver.2 Insert the plug of the external powersupply adapter with a cigarette lighter plug(SDD-13) in the EXT DC IN jack of thetransceiver.3 Insert the cigarette lighter plug of theexternal power supply adapter in thecigarette lighter socket of the vehicle.Cautionsy The SDD-13 is compatible with a 12 V DC cigarette lighter socket. Do not connect the SDD-13 to a24 V DC cigarette lighter socket.y Use the transceiver at the minimum required transmit power level to prevent overheating.y Do not continue transmitting for a prolonged period of time. The transceiver may overheat, resultingin malfunction or burns.y To operate the transceiver for 7 hours or longer, it is recommended that the battery pack be replacedwith the optional battery case (FBA-39).y Recharging the fully-charged battery pack repeatedly can shorten its service life. Be extremely carefulnot to continually recharge the battery when operating the transceiver using an external power supply.y While charging the battery pack, protect the transceiver from water.y Charge the battery pack in a place where the ambient temperature is +5 °C to +35 °C (+41 °F to +95°F).y If the terminal or electrode of the battery pack is dirty, the transceiver can malfunction due to poorcontact, resulting in overheating or rupture. If the terminal or electrode gets dirty, clean it using a drycloth or cotton swab.Tips• The SBR-14LI battery pack can be charged in approximately 9.0 hours using the external powersupply (approximately 5 hours to charge the optional battery pack FNB-101LI). If the transceiver isturned on while the battery pack is charging, the charging time will increase slightly.• Charging stops automatically when the battery pack has been fully charged.• The external power supply can be used with the battery case installed.• If the transceiver is connected to the external power supply with the transceiver turned off,“CONNECTED TO EXTERNAL POWER” appears on the LCD for about 20 seconds later “BATTERYNOT INSTALLED” appears.To cigarette lightersocket of vehicleEXT DC IN jackExternal powersupply adapter witha cigarette lighter plugSDD-13（optional）
