Note

 

 

When you use the radio, it is recommended that you use a fully charged rechargeable battery or a new dry battery since more power is consumed by the radio than by MD playback.

When to replace the batteries

When the dry battery or rechargeable battery is weak, flashing r or ÒLOW BATTÓ appears in the display. Replace the dry battery or charge the rechargeable battery.

The battery level indicator is approximate. It may be more or less than the indication depending on the operating condition.

Note

Stop the recorder before replacing battery.
