Rotate the 5-pin plug to align
with the pins in the jack on the
transmitter. Insert the plug until
it latches in place.
Press the black button to re-
move the plug from the trans-
mitter.
The connector fits standard
3-pin XLR jacks. A spring-
loaded collar on the trans-
mitter adapts to provide a
secure fit on a wide variety
of different microphones.
Adjust the gain while speaking into the microphone and
observing the LEDs on the transmitter and/or the re-
ceiver.
Adjust the level control so that the “-10” LED blinks green
or stays lit during normal speech and the “-20” LED oc-
casionally blinks red on louder peaks.
