When battery power is low, (FNýâ8KK<IPü appears and the scanner beeps continuously. When battery power is depleted, the scanner turns itself off. Replace all four non-rechargeable batteries, or recharge the recharge- able batteries. See “Charging Rechargeable Batteries” on Page 12.

Warning: Always dispose of old batteries promptly and properly. Do not bury or burn them.

Caution: If you do not plan to use the scanner with bat- teries for a month or longer, remove the batteries. Bat- teries can leak chemicals that can destroy electronic parts.

Charging Rechargeable Batteries

Your scanner has a built-in charging circuit that lets you charge nickel-metal hydride (Ni-MH) or nickel cadmium (Ni-CD) rechargeable batteries (not supplied) while they are in the scanner. To charge rechargeable batteries, connect an appropriate AC or DC adapter to the PWR DC 9V jack. For best results we recommend RadioShack re- chargeable nickel-metal hydride (Ni–MH) 1500mAh bat- teries.

Notes:

•To charge batteries with a DC adapter from a DC power source, you must use a 9V, 300 mA DC adapter such as RadioShack Cat. No. 273-1810 or 273-1815 and a size C Adaptaplug™ (neither sup- plied). Both are available at your local RadioShack store. Make sure the adapter's voltage is set to 9V.

•It takes about 15 hours to recharge fully discharged 1500mAh Ni–MH rechargeable batteries. You can operate the scanner while recharging the recharge- able batteries, but charging takes longer.

•The scanner can also charge Ni-Cd batteries. 600mAh batteries require 6 hours and 850mAh bat- teries require 8 hours to charge.

•When you charge Ni-Cd batteries, pay attention not to over charge. Overcharging shortens battery life.
