Important Information About the PWR and CHG Jacks

There are two external jacks on the left side of the scanner — PWR and CHG. It is important that you understand the purpose of each jack before you connect any adapter to the scanner.

The PWR jack powers the scanner and disconnects the internal batteries. You can use this jack with either an AC adapter or DC cigarette lighter adapter, regardless of the type of batteries you in- stalled.

The CHG jack powers the scanner and also charges the internal batteries. The CHG jack is covered by a plastic plug. Use the CHG jack only when rechargeable nickel-cadmium batteries are in- stalled.

Warning: Never use the CHG jack with non-rechargeable batter- ies installed. If you try to recharge non-rechargeable batteries, they become very hot and could explode.

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 batteries, simply connect an AC or DC adapter to the scan- ner’s CHG jack (see “Connecting Optional Power Sources” on Page 33).
