RF interference
RF signal is weak.
There can be a lot of RF interference
outdoors.
Try moving indoors, where there is
less RF interference.
Overhead telephone lines,
fluorescent lighting, and metal
fences can all cause interference.
Turn off all nearby computers and
mobile phones.
Make sure there is an unobstructed
line of sight between the transmitter
and the receiver.
Keep in mind that your body,
clothes, and onstage sets are
possible obstructions.
Make sure the receiver and the
transmitter are within 197' (60m)
range. If there are obstructions, you
may need to move closer.
