playback sound when you turn up the volume.

avoid overcharging (more than 20 hours) when charging has been
completed.

• Charging and operation should be made in temperature ranges 5°C to

40°C (40°F to 104°F).

• The charge adaptor will become warm during charging but this is not a

sign of problem.

• Do not use or leave the charge adaptor in a location near heat sources or

in a place subject to direct sunlight or excessive moisture.
