Never heat, disassemble, or throw batteries into a fire.

Never leave dead, old, or weak bat- teries in the calculator. They can leak chemicals that corrode or damage electronic circuits.

Important: This calculator is capable of using rechargeable nickel-cadmium batteries. At the end of the batteries’ useful life, they must be recycled or dis- posed of properly. Contact your local, county, or state hazardous waste man- agement authorities for information on recycling or disposal programs in your area. Some options that might be avail- able are: municipal curb-side collec- tion, drop-off boxes at retailers, recycling collection centers, and a mail- back program.

Using AC Power

You can power the calculator from stan- dard AC power, using an AC adapter such as Cat. No. 273-1664 (not sup- plied).
