In case of distorted sound:
• 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 high. Adjust the volume
on the base station/headphone to a lower level.
• Adjust the headphone’s tuning frequency. Press and hold the tuning
control button for about 1 second. Repeat if necessary until the system
status LED turns green.
• Adjust the transmitter’s frequency. Select any of the 4 channels of the
transmitter. Next adjust the headphone’s frequency by pressing the tuning
button.
• Headphone batteries empty. Recharge the headphone’s batteries
(SBC EH2412/00).
• Distance from the transmitter is too large. Move closer to the
transmitter.
• Interference from fluorescent lamps/ other radio sources. Move
transmitter or headphone elsewhere/ change the transmitter’s channel.
• Make use of the HD1500U transmitter. Some transmitters already built
into other equipment may not be compatible with the HD1505U
because of the advanced technologies used in the HD1505U headphone.
• Check whether the audio output connector of your audio source is
connected to the correct audio input connector of the HD1500U base
station.
