blink and display ID. The status LED of the corresponding transmitter will alternately flash red and green for approximately 45 seconds.
Manually Selecting a Group and Channel
Specific groups and channels can be assigned to the receiver instead of using the automatic scan function.
Note: Group 3 should only be used in controlled Wi-Fi environments to prevent interference from unexpected Wi-Fi devices.
Selecting a Group
1. Press and hold the group button for 2 seconds until the group display
flashes.
2. Press the group button to scroll through the available groups.
3. The receiver will automatically save the selected group.
Selecting a Channel
1. Press and hold the channel button for 2 seconds until the channel
display flashes.
2. Press the channel button to scroll through the available channels.
3. The receiver will automatically save the selected channel.
Note: A double dash symbol
--
displayed on the receiver screen during a channel
scan indicates that there are no available channels within the selected group.
Choose a group with more channels and repeat set up steps.
The controls of the receiver and transmitter can be locked to prevent accidental or unauthorized changes to settings.
Note: Locks are not affected by power cycles.
Use the gain buttons on the receiver to increase or decrease the gain of a
linked transmitter:
• Turn on the linked transmitter and momentarily press the gain
buttons to adjust the gain in 1 dB increments
• For faster gain adjustments, press and hold the gain buttons
Tip: Monitor the audio and observe the receiver audio meter level while adjusting the
gain to prevent signal overload.
To activate Remote ID:
1. Momentarily press the link button on the transmitter or receiver.
2. The LCD of the linked receiver will blink and display ID and the status
LED on the linked transmitter will flash red/green.
3. To exit Remote ID mode, momentarily press the link button or allow the
function to timeout.
Locking the Transmitter Power Switch

turning on the transmitter. Continue to hold the link button until the lock icon
appears on the receiver LCD. Repeat sequence to unlock.
Optionally, the transmitter power switch can be remotely locked from the receiver front
