Warning: Never set ALKALINE JACK NI-CD to NI-CD if you are installing non-rechargeable batteries. Non-rechargeable batteries can get hot or explode if you try to recharge them.

3.Install two batteries in the compartment and two in the cover as indicated by the polarity symbols (+ and –) marked inside those locations.

Cautions:

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

•Always remove old or weak batteries. Batteries can leak chemi- cals that destroy electronic circuits.

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

4.Replace the cover.

If BATT.Lo flashes and the scanner beeps every 15 seconds, replace (alkaline) or recharge (rechargeable nickel-cadmium) the batteries.

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