When charging completes, the LEDs unlight; remove the charger plug from the transceiver DC IN jack. 5Unplug the charger from the AC wall outlet. Note: uIf you turn the transceiver ON and press [F], [LOW/ BATT] while charging the battery pack, ÒCHARGINGÓ appears. ÒSTANDBYÓ appears when the charging completes. uThe transceiver becomes warm while charging the battery pack. uIf the charger plug is plugged into the DC IN jack before the battery pack is attached, turn the transceiver ON and then OFF again to initiate the charging. uExceeding the specified charge period shortens the useful life of the Li-ion battery pack. uThe provided charger is designed to charge only the provided PB-42L Li-ion battery pack. Charging other models of battery packs may damage the charger and battery pack. uDo not press [PTT] while charging. uThe battery pack must be kept in cool and dry place. uNever leave the battery pack in the direct sun light. CONNECTING TO A CIGARETTE LIGHTER SOCKET To connect the transceiver to the cigarette lighter socket in your vehicle, use an optional PG-3J Cigarette Lighter cable. While the PG-3J is connected to the cigarette lighter plug, the transceiver automatically start charging the Li-ion battery pack (PB-42L). When you operate the transceiver, it charges the Li-ion battery pack in back ground. If the transceiver is turned OFF, the 2 LEDs light orange while charging. When the charging completes, they turn OFF {above}. To connect with an external 24 V power source via a DC-DC converter, only use the optional PG-3J Cigarette Lighter cable. Using the PG-2W DC cable in this situation may cause a fire. PG-2W 24V 12V 24VPG-3J 12V 12V 24VPG-3J Note: If the input voltage exceeds approximately 16.5 V, warning beeps sound and ÒVOLTAGE ERRORÓ appears. CONNECTING TO A REGULATED POWER SUPPLY To connect the transceiver to an appropriate regulated power supply, use an optional PG-2W DC cable. 1Confirm that the power of both the transceiver and the power supply are OFF. 2Connect the optional PG-2W DC cable to the power supply; the red lead to the positive (+) terminal, and the black lead to the negative (Ð) terminal. 3Connect the barrel plug on the DC cable to the DC IN jack of the transceiver. If the transceiver is turned OFF while a regulated power supply is connected with the DC IN jack, it automatically initiates charging the Li-ion battery pack (PB-42L) {above}. Note: uIf the DC power supply voltage is below 12.0 V DC, you may not be able to charge the Li-ion battery pack (PB-42L). uThe supply voltage must be between 12.0 V and 16.0 V to prevent damaging the transceiver. If input voltage exceeds approximately 16.5 V, warning beeps sound and ÒVOLTAGE ERRORÓ appears. Remove the DC IN jack plug immediately. uIf the DC power supply voltage is above 14.5 V DC and ÒHÓ (High Power) is selected, ÒHÓ icon blinks and the output power is reduced to ÒLÓ level (Low Power) automatically {page 41}.
