Nickel-cadmium battery packs come fully discharged. You can charge the special-order batteries while they are in the battery compartment using an AC adapter (such as Cat. No. 273- 1664, not supplied) or DC adapter (such as Cat. No. 273-1801, not sup- plied).

Warning: Do not try to charge non- rechargeable batteries. The batteries can become very hot and possibly ex- plode.

Follow these steps to recharge nickel- cadmium battery packs while they are in the battery compartment.

1.Connect an AC or DC adapter. See “Using AC Power” on Page 7 or “Using Vehicle Battery Power” on Page 8.

Notes:

•It takes about 15 hours to charge fully discharged nickel- cadmium batteries.

•You can play a CD while recharging the batteries; how- ever, this could cause the bat- teries to recharge more slowly.

2.When the nickel-cadmium battery packs fully charge, unplug the adapter from the AC outlet or cig- arette lighter socket, then discon- nect the adapter from the CD player.

Charging Tips

•Always keep the charging termi- nals clean. Use a cotton swab dipped in alcohol to clean the ter- minals.

•Under normal usage conditions, the nickel-cadmium battery packs can be recharged about 500 times.

•Fully discharge the battery packs occasionally by playing the CD player until it no longer plays. Then fully recharge the battery packs. This helps restore the bat- tery packs’ full charging capacity.

•Avoid charging the batteries in a hot environment (more than 113°F) as this can permanently reduce the battery packs’ charg- ing capacity.

•Do not overcharge the battery packs. Overcharging can severely reduce the battery packs’ useful life.

•Do not short-circuit the battery packs’ terminals (+ and –).
