Note: 

If you want to stop the scan, push the group button again.

2. Turn on transmitter and change the group and channel to match the receiver (See Setting Transmitter Group 

and Channel).

Once the system is set up, perform an audio check and adjust the gain if necessary.

Setting Transmitter Group and Channel

Transmitter group and channel must be manually set to match the receiver.

Group (letter)

1. Press and release the group button on the transmitter to activate the display. Press the group button again and 

the display flashes.

2. While the display is flashing, press the group button again to advance to the desired group setting.

Channel (number)

If channel needs to be changed, follow the same procedure using the channel button instead of the group button.

Note:

• When the group and channel correctly match the receiver, the RF bars and battery LED on the receiver illumi­

nate.

After manual setup, the transmitter alternately displays the group and channel setting for about two seconds.

Multiple System Set Up

Up to 12 systems can operate simultaneously (band and RF environment dependent).

Important:

 Set up each system one-at-a-time. Once a receiver and transmitter are tuned to the same group and 

channel, leave the transmitter powered on. Otherwise, scans from the other receivers will not detect that channel 

as occupied.

Turn 

on

 any other equipment that could cause interference during the performance so it will be detected during the 

group and channel scans in the following steps.
