Radio Shack PRO-79 owner manual Charging Rechargeable Batteries

Cautions:

You must use a power source that supplies 9V DC

!and delivers at least 300 mA. Its center tip must be

set to positive and its plug must fit the scanner's PWR jack. Using an adapter that does not meet these speci- fications could damage the scanner or the adapter.

•Always connect the DC adapter to the scanner before you connect it to the power source. When you finish, disconnect the adapter from the power source before you disconnect it from the scanner.

To power the scanner using a DC adapter, attach the Adapta- plug adapter to the DC adapter so the tip reads positive (+) and set the adapter’s voltage switch to 9V. Next, insert the Adapta- plug adapter into the scanner’s PWR jack, then plug the DC adapter into your vehicle’s cigarette lighter socket.

Note: If you use a cigarette lighter power cable and your vehi- cle’s engine is running, you might hear electrical noise from the engine while scanning. This is normal.

CHARGING RECHARGEABLE BATTERIES

Your scanner has a built-in charging circuit that lets you charge Ni-Cd rechargeable batteries while they are in the scanner. To charge rechargeable batteries, simply connect an AC adapter to the scanner’s PWR jack.

Notes:

•You must have installed Ni-Cd rechargeable batteries in the supplied yellow rechargeable battery holder in order to charge them while they are in the scanner. If you use Ni-MH or high-capacity Ni-Cd batteries in your scanner, you must use an external charger to charge them.

•You cannot use a DC adapter to recharge rechargeable bat- teries in the scanner due to the limitations of the scanner’s charging circuit.

It takes between 14 and 16 hours to recharge rechargeable bat- teries that are fully discharged. You can operate the scanner while recharging the batteries, but charging takes longer.
