Radio Shack PRO-83 manual Using Rechargeable Batteries

Warning: Set ALKALINE/RECHARGEABLE to RECHARGEABLE for use only with nickel cadmium (Ni-Cd) or nickel metal hydride (Ni-MH) rechargeable batteries. Never attempt to recharge non- rechargeable batteries. Non-rechargeable batteries can get hot or explode if you try to recharge them.

Cautions:

•Use only fresh batteries of the required size and recommended type.

•Always remove old or weak batteries. Batteries can leak chemicals that destroy electronic circuits.

•Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities.

When flashes and the scanner beeps every 15 seconds, replace both batteries.

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

Using Rechargeable Batteries

You can also use two rechargeable batteries to power your scanner. Before you use Ni-Cd or Ni-MH batteries, you must charge them.
