QUICK START
1. Insert batteries confirming to “+” and “-”.
Incorrect installation will result in not
working or damaging the microphone set.
2. Make sure to turn down the volume of
your speaker before you plugging the
receiver into the 1/4’’ (6.35mm) mic input
of it.

direct line of 'sight' for them to work.

receiver as high as possible and keep

keep out from the rain and keep it dry.
