Kenwood TH-F7E Connecting to a Cigarette Lighter Socket, Connecting to a Regulated Power Supply

1 PREPARATION

CHARGING THE Li-ion BATTERY PACK

The Li-ion battery pack can be charged after it has been installed onto the transceiver. The battery pack is provided uncharged for safety purposes.

1 Confirm that the transceiver power is OFF.

• While charging the battery pack, leave the

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.

2 Insert the charger plug into the DC IN jack of the

transceiver.

3Plug the charger into an AC wall outlet.

•Charging starts and 2 LEDs on the top panel lights orange.

4It takes approximately 6.5 hours to charge an empty PB-42L Li-ion battery pack. 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:

◆If you turn the transceiver ON and press [F], [LOW/ BATT] while charging the battery pack, “CHARGING” appears. “STANDBY” appears when the charging completes.

◆The transceiver becomes warm while charging the battery pack.

◆If 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.

◆Exceeding the specified charge period shortens the useful life of the Li-ion battery pack.

◆The 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.

◆Do not press [PTT] while charging.

◆The battery pack must be kept in cool and dry place.

◆Never 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.

DC IN jack

DC 12 V

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

Note: If the input voltage exceeds approximately 16.5 V, warning beeps sound and “VOLTAGE ERROR” 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 (–) terminal.

Fuses (4 A)

3Connect the barrel plug on the DC cable to the DC IN jack of the transceiver.

DC IN jack

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:

◆If 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).

◆The 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 “VOLTAGE ERROR” appears. Remove the DC IN jack plug immediately.

◆If the DC power supply voltage is above 14.5 V DC and “H” (High Power) is selected, “H” icon blinks and the output power is reduced to “L” level (Low Power) automatically {page 41}.
