CAUTION
D Do not drive with using the headphone. Otherwise,
you may be hard to hear the sound from the outside
while using the headphone and may cause an
accident.
D With DVD player:
Conversational speech on some DVDs is recorded at
a low volume to emphasize the impact of sound
effects. If you adjust the volume assuming that the
conversations represent the maximum volume level
that the DVD will play, you may be startled by louder
sound effects or when you change to a different
audio source. Be sure to adjust the volume with this
in mind.
Make sure the volume is not increased, before you
turn on the headphone.
NOTICE
To prevent the battery from being discharged, do not
leave the car audio on longer than necessary when the
engine is not running.
