4.Plug the other end of the adapter into your vehicle’s cigarette- lighter socket.

Note: If the scanner does not operate properly when you use a DC adapter, unplug the adapter from the cigarette-lighter socket and clean the socket to remove ashes and other debris.

CHARGING NICKEL-CADMIUM BATTERIES

The scanner has a built-in charging circuit that lets you recharge nickel- cadmium batteries while they are in the scanner. To charge the batter- ies, remove the plug from the scanner’s CHARGE jack and connect an optional AC adapter or DC adapter to the jack (see “Using Standard AC Power” on Page 10 or “Using Vehicle Battery Power” on Page 11).

Warning: Do not connect an adapter to the scanner’s CHARGE jack if you installed non-rechargeable batteries (standard, extra-life, or alka- line). Non-rechargeable batteries become hot and could explode if you try to recharge them.

It takes about 14 to 16 hours to recharge batteries that are fully dis- charged. You can operate the scanner while recharging the nickel- cadmium batteries, but charging takes longer.

Note: Nickel-cadmium batteries last longer and deliver more power if you occasionally let them fully discharge. To do this, simply use the scanner until it begins beeping every 15 seconds and BATT.LO ap- pears. Then fully charge the batteries.

Important: At the end of a rechargeable battery’s useful life, it must be recycled or disposed of properly. Contact your local, county, or state hazardous waste management authorities for information on recycling or disposal programs in your area. Some options that might be avail- able are: municipal curb-side collection, drop-off boxes at retailers such as your local RadioShack store, recycling collection centers, and mail- back programs.
