PREPARATION

POWER SOURCES

You can power your scanner from any of three sources:

Built-in rechargeable battery pack

Standard AC power using the supplied AC adapter/ charger

Vehicle battery power using an optional DC ciga- rette-lighter power cable

Using the Rechargeable Battery Pack

You must charge your scanner’s built-in rechargeable battery pack before you can use it to power the scanner. Your scanner has a built-in charging circuit that lets you charge the rechargeable battery pack while it is in the scanner.

To charge the battery pack, simply connect the supplied AC adapter/charger or an optional DC cigarette-lighter

power cable to the scanner’s jack. See “Using Standard AC Power” on Page 9 or “Using Vehicle Bat- tery Power” on Page 10.

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

Notes:

The scanner automatically stops charging the bat- tery pack when it is fully charged, even if the sup- plied AC adapter/charger or a DC cigarette-lighter power cable is still connected to the scanner.

A rechargeable battery pack lasts longer and deliv- ers more power if you occasionally let it fully dis- charge. To do this, simply use the scanner until the low battery indicator appears. Then fully charge the battery pack.

If the battery pack doesn’t power the scanner even after you charge it, you must replace it. You can order a re- placement battery pack from your local RadioShack store.
