• Fully discharge the batteries occa­sionally by playing the CD player until it no longer plays. Then fully recharge the batteries. This helps restore the batteries’ full charging capacity.
• Avoid charging the batteries in a hot environment (above 113°F) as this can permanently reduce the batteries’ charging capacity.
Caution: Do not overcharge the bat­teries. Overcharging can significantly reduce the batteries’ useful life.
Important: Th is CD player is c apable of using rechargeable nickel-cadmium batteries. At the end of the batteries’ useful life, they must be recycled or disposed of properly. Contact your lo­cal, county, or state hazardous waste management authorities for informa­tion on recycling or d isposal program s in your area. Some options that might be available are: municipal curb-side collection, drop-off boxes at retailers such as your local RadioShack store, recycling collection centers, and mail ­back programs.

3. Close the battery compartment cover.
Replace or recharge the batteries when flashes on the display, the sound distorts, or the volume weak­ens.
Cautions:
• Always dispose of old batteries promptly and properly; do not burn or bury them.
