4.When charging is complete, unplug the battery charger’s plug from the AC outlet. Then, disconnect the bat- tery charger’s barrel plug from the

POWER jack.

Note: You can use an external charger (such as Cat. No. 23-134, not sup- plied) to recharge the nickel-cadmium batteries. After removing the batteries from the TRC-235, follow the instructions that come with the external charger.

Important: Your TRC-235 is capable of using nickel-cadmium batteries. At the end of the batteries’ useful life, they must be re- cycled or disposed of properly. Contact your local, county, or state hazardous waste management authorities for informa- tion on recycling or disposal programs in your area. Some options that might be available are: municipal curbside collec- tion, drop-off boxes at retailers such as your local RadioShack store, recycling col- lection centers, and mail-back programs.

USING VEHICLE BATTERY POWER

You can power your TRC-235 from your vehicle’s cigarette-lighter socket with an optional 12-volt DC fused power cord (such as Cat. No. 270-1533).

•You must use a DC fused cord that supplies 12 volts and delivers at least 1000 milliamps of vehicle power. Its center tip must be set to positive, and its plug must correctly fit the TRC-235’s POWER jack. The recommended fused cord meets these specifications. Using a fused cord that does not meet these speci- fications could damage the TRC-235 or the fused cord.
