Troubleshooting
The transmitter and receiver do not start
Charge the transmitter and receiver. Remember to press the On/Off button
down for 2 seconds to switch the unit on. Check that the charger is connected
to the plug socket.
Poor speech intelligibility
The distance between the transmitter and the receiver may be too long. The
range is around 30 metres. The distance between the microphone and the
person who is talking may also be too long; move the microphone nearer to
the person talking. Try to change channel/environment.
Poor range and interference
In some environments involving, e.g., concrete, iron or sheet metal
structures, the range may be reduced. There may also be equipment
nearby causing interference. Change channel.
No sound
Check that the transmitter and receiver are set to the same channel.
Loud hissing noise (no sound transfer)
Check that the units are paired.
The unit will not start during charging
Disconnect the charger. Choose Settings - Charge - Auto power off in the
