Each scan pass takes about 20 seconds. After the
scan on the first receiver is completed, the receiver
will be set to the newly identified frequency. A mes-

transmitter and transfer the settings from the receiver.
To set up the transmitter, turn its power on, connect it
with the USB cable, select SEND TX SET and press
the encoder to start the transfer.

actual operation and have the user speak or sing at
the loudest level that will occur during use, or set the
output level of the instrument or audio device to the
maximum level that will be used.

6) Always leave the transmitter gain adjustment set
according to these instructions. Adjustment only
needs to be made if a different person, microphone,
microphone placement, or a different instrument is
used. Do not change it to adjust the audio output
level of the receiver. If the audio output level of the
receiver is too high or low, use only the controls on
the receiver to make that adjustment.
