Recharging Nickel-Cadmium Batteries

If you connect the supplied DC adapter (see “Using Vehicle Battery Power” on Page 8) or an AC adapter (see “Using AC Power” on Page 9) to the CD player, you can set the CD player to charge nickel-cadmium batteries while they are inside the CD player’s battery compart- ment.

Cautions:

•Use only the supplied DC adapter or an AC adapter that meets the speci- fications in “Using AC Power” on Page 9 to recharge the batteries in the CD player. Other adapters could damage your CD player or the bat- teries.

•Do not use the CD player or open the CD compartment cover while you are charging nickel-cadmium batteries.

•Nickel-cadmium batteries charge more efficiently if the temperature is above 40°F (4.5°C) and below 90°F (32°C).

2.With rechargeable batteries in- stalled and the CD compartment cover closed, press STOP/CLEAR. CHG flashes on the display. Then CHG CHG CHG appears and the CD player starts to recharge the batter- ies.
