Problem
No transmission / no sound
Interference can be heard during
transmission
Possible cause
Devices are outside range
Batteries are empty
Connection cut off
Incoming signal not loud enough
Interference on channel
Batteries are almost empty
Devices are on outer margin of
range
Position of transmitter
Interference caused by microwave
or W-Lan (WiFi)
Solution
Reduce distance between devices.
If ordinary batteries are used, replace them.
If you use the supplied batteries, charge them.
Check that all cable connections are correctly made.
Increase the volume of the incoming signal (music, etc.). The
automatic cut-off switches off transmission when the signal is
too weak or missing.
Change the channel using the Auto-Tuning function.
The batteries are almost empty and need to be replaced. If you
use the supplied batteries – charge them.
Transmitter and RF headphone are too far apart. Bring the RF
headphone closer to the transmitter.
In some cases it may be necessary to place the transmitter
somewhere else or higher.
Place the transmitter at least
1 m away from the microwave or W-Lan (WiFi).
