Note: This system may beinterfered by radio wave.
Check receiver andmicrophone power.
Make sure transmitterand receiver frequencyis same.
Check if amplifieror other equipment'spower is on.Check if the
connection between receiverand mixer oramplifier is proper.
Check microphone batterypower.
Check receiver antennasconnection.
Check if receiveris too closeto metal partsor there is barrier
between transmitter andreceiver.
Make sure microphonebattery is installedfirmly and thereis no
interferential source.
Check if signalcable is wellconnected.
Check receiver antennasconnection.
When using 2or more microphoneset simultaneously, make
sure the frequenciesare not interferedeach other.
Check if theinterference comes fromother wireless microphone,
