Troubleshooting

If a fault occurs, first check the points listed below. If you are unable to
remedy a problem by following these hints, contact the helpline or consult
your dealer. Never try to open the set yourself as this will void the
guarantee.
First, check all cables to ensure that they are connected correctly.
In case of no sound:
• Check if the audio source is switched on and tuned to a channel with
audio.
• In case of an audio source with adjustable output level: adjust the output
level of the audio source to a higher and non-distorted level.
• Volume on base station or headphone is set too low.
• Adjust the volume on the base station/headphone to a higher level.
• Adjust the headphone's tuning frequency. Press and hold the tuning
control button for about 1 second.
• Make use of the HD1500U transmitter. Some transmitters already built
into other equipment may not be compatible with the HD1505U
headphone because of the advanced technologies used in the HD1505U
headphone.
• The audio signal from your SACD player is upsampled. Lower the
sampling rate through the SACD player's menu to 44.1 kHz
• The audio signal from your DVD player is upsampled: lower the PCM
sampling rate through the DVD player's menu to 48 kHz.
• Invalid digital audio signal: the 'DIGITAL' indication LED in the HD1500U
display window will be illuminated in red. Change the digital audio signal
(for exampling: by changing from MP3 to audio CD) or switch to the
analog input signal of the HD1500U base station.
• Check whether the audio output connector of your audio source is
connected to the correct audio input connector of the HD1500U base
station.
