1) Battery is inserted backwards or dead.
2) Transmitter not powered up. (See Operating Instructions,

Either use the remote control to wake it up again or remove
and reinsert the transmitter's battery.
1) Gain control set to minimum.
2) Battery is dead or installed backwards. Check PWR LED.

7) Defective transmitter antenna.
1) Receiver output level set too low.
2) Receiver output disconnected, or cable defective or mis-wired.

Modulation LEDs and receiver audio levels as SM is being used.
2) Receiver output may be mis-matched with the sound system or
recorder input. Adjust output level on receiver to the correct level
for the recorder, mixer or sound system. (Use the receiver's Tone
function to check level.)
3) Excessive wind noise or breath "pops." Reposition microphone
and/or use a larger windscreen.
4) Transmitter is not set to same frequency as receiver. Check that
operating frequency on receiver and transmitter match.
