The POWER jack powers the scanner and disconnects the internal bat- teries. You can use this jack to connect an external power source (AC or DC adapter), regardless of the type of batteries you install.

The CHARGE jack supplies power to operate the scanner and also charges the internal batteries. Use the CHARGE jack only when you have installed rechargeable nickel-cadmium batteries.

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

Remove the plastic plug from the CHARGE jack before you use it, then replace the plug when you finish.

USING STANDARD AC POWER

To power the scanner from AC power, you need an AC adapter such as RadioShack Cat. No. 273-1665. Plug the adapter’s 3.4 mm outer di- ameter/1.3 mm inner diameter barrel plug into the scanner’s POWER jack. Then plug the adapter’s power module into a standard AC outlet.
