Insert the plug (3.5 mm) of the headset into the transmitter input (6) and the headphone plug (3.5 mm) into the receiver (6). Make sure that the plug is fully inserted into the device.
When the transmitter channel changes, the enabled receivers automatically synchronise with the transmitter channel.
Using buttons (3) and (5) allows to set the volume level from 1 to 8 (a flashing volume icon indicates that the device is completely muted).
The receivers remember the last volume level setting and remain on that setting when switched on again.
Receivers and transmitters turn off automatically while charging. To use the device while charging, turn it on again.
