AUDIO 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. 278
