20Basic OperationPreparationConnecting an External Power Supply for Use in Vehicle(USA/EXP version only)The optional external power supply adapter witha cigarette lighter plug (E-DC-5B) allows thetransceiver to be used in a vehicle.1 Turn off the transceiver.2 Insert the plug of the external power supplyadapter with a cigarette lighter plug (E-DC-5B) in the EXT DC IN jack of the transceiver.3 Insert the cigarette lighter plug of the externalpower supply adapter (E-DC-5B) in thecigarette lighter socket of the vehicle.Cautions The E-DC-5B is compatible with a 12 VDC cigarette lighter socket. Do not connect the E-DC-5B tothe 24 VDC cigarette lighter socket. Use the transceiver at the minimum required transmission power level to prevent overheating. Do not continue transmission for a prolonged period of time. The transceiver may overheat, resultingin malfunction or burns. If you operate the transceiver for 7 hours or longer, it is recommended that you remove the batterypack and install the optional battery case (FBA-39). Recharging the fully-charged battery pack repeatedly can shorten its service life. Be extremelycareful not to do so when you operate the transceiver when using an external power supply. While charging the battery pack, protect the transceiver from water. Charge the battery pack in a place where the ambient temperature is +5 °C to +35 °C (+41 °F to+95 °F). If the terminal or electrode of the battery case 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 battery pack can be charged within approximately 5 hours using the external power supply(approximately 8 hours to charge the optional battery pack FNB-102LI). If the battery pack ischarged with the transceiver turned on, the charging time increases slightly.• When the battery pack has been fully charged, charging stops automatically.• The external power supply can be used with the battery case installed.• If you connect the transceiver to the external power supply with it turned off, “CONNECTEDTO EXTERNAL POWER” appears on the LCD, and about 20 seconds later “BATTERY NOTINSTALLED” appears.Connecting to an External Power Supply Using a Power Cable(USA/EXP version only)The optional power cable (E-DC-6) allows the transceiver to be connected to an externalpower supply.To cigarette lighter socketof vehicleEXT DC IN jackExternal power supplyadapter with a cigarettelighter plugE-DC-5B (option)
