Notes:

•If you installed rechargeable nickel-cadmium batteries in the transceiver, connect the DC power cord to the DC13.8V CHARGE jack and be sure the NI/AL switch is set to NI. This pow- ers the transceiver and recharges the batter- ies at the same time. See “Charging Nickel- Cadmium Batteries.”

•If the transceiver does not operate when you use the power cord, unplug the cord from the cigarette lighter socket and clean the socket to remove ashes and debris. If it still does not operate properly, check the in-line fuse in the power cord.

Using Standard AC Power

You can operate the transceiver from AC power us- ing a 12-volt DC power supply (such as Cat. No. 22- 120, not supplied), a DC cigarette lighter power cord (such as Cat. No. 270-1534, not supplied), and a cig- arette lighter accessory outlet (such as Cat. No. 270- 1539, not supplied).

Cautions:

•You must use a DC power cord that supplies 12 volts and delivers at least 2.5 amps. Its center tip must be set to positive, and it must have a plug that properly fits your transceiver’s DC13.8V CHARGE jack. The recommended power cord meets these requirements. Using a power cord that does not meet these specifications could damage the transceiver or the power cord.

•Be sure you connect the DC power cord to the transceiver before you connect it to the power supply. Then disconnect the power cord from the power supply before you disconnect it from the transceiver.

Note: Most 12-volt DC power supplies plug into a standard AC outlet to produce DC power. Before connecting your transceiver to a 12-volt DC power supply, read and follow the instructions included with the power supply.
