Note: when the microphone is active, please do not put it on the receiver, otherwise interference can occur!
1 - When several units are used at the same time and in the same place, you should choose frequencies from low to high, according
to the distance to the receivers.
2 – If interference happens between multiple units, adjust that unit individually.
There should be at least 1.5 MHz between each system frequency.
3 - To avoid any possible wireless interference caused by the other audio equipment
please keep the receiver away from them by around 0.5 meter.
4 - Sometimes the external environment can cause wireless interference. In such cases,
adjust the frequency until there is no interference.
5 – For best range, always keep the receiver in ‘free space’ and avoid placing it in a flight case, cabinet or cupboard. Range can also
be affected by the number of people in the room between the mic and the receiver.

display will light up and the bar displays “ ”will be full. This indicates that the frequency setup has been completed.
Check that the frequency of the receiver and microphone are the same. If they are not then repeat the operation above.
