Notes:

Mobile use of this scanner is unlawful or requires a permit in some areas. Check the laws in your area.

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

Charging a Rechargeable Battery Pack

Your scanner has a built-in charging circuit that lets you charge a rechargeable battery pack (Cat. No. 23-288) while it is in the scanner. To charge the battery pack, sim- ply connect an AC or DC adapter to the scanner’s PWR/DC 9V jack.

It takes about 14–16 hours to recharge a battery pack that is fully discharged. You can operate the scanner while re- charging the battery pack, but charging takes longer.

Notes:

If you want to take the battery pack out of the scan- ner to charge it, follow the instructions in “Using Bat- teries” on Page 9 to remove it, then follow the instructions provided with the battery pack to charge it.

A rechargeable battery pack lasts longer if you let it fully discharge once a month. To do this, simply use the scanner until BATT flashes and the scanner beeps about every 3 seconds. Then fully charge the battery pack.
