Solution
Make sure that the On/Off switch (B7) on the headphones is in the „ON" position.
Are the power-on lamps on the transmitter (A1) and the headphones (B10) constantly lit?
Check whether the AC adapter (C) is correctly connected and check the condition of the battery
packs. Details in sections 4 and 5.
Check whether the audio source is switched on and emitting a signal.
Have you connected the transmitter to the audio source?
If you are operating via an adjustable headphones socket on your audio source, make sure that it
is turned up high enough (e.g. to about the middle setting).
Use the frequency selection control (A3) to change to a different transmission frequency.
Activate the frequency search (B9) again.
Make sure that the interference is not being caused by your audio source.
In certain cases it may be necessary to alter the position of the transmitter horizontally and/or
vertically.
Check the power-on lamp (B10). See section 5.
Do not place the transmitter directly in front of a television set, but at a distance of approx. 1 m.
Increase the volume at the headphones socket or the phono output of your audio source.
If the audio signals are too weak the transmitter will otherwise switch off automatically.
