transmitter:
• Turn on the linked transmitter and momentarily press the gain buttons to adjust

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 sta-
tus LED on the linked transmitter will flash red/green.
3. To exit Remote ID mode, momentarily press the link but-
ton or allow the function to timeout.
Selecting a Channel
1. Press and hold the channel button for 2 sec-
onds 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 chan-
nel scan indicates that there are no available channels within the selected group.
Locking the Transmitter Power Switch
Starting with the transmitter set to off, press and hold the LINK button while turning on
the transmitter. Continue to hold the link button until the lock icon appears on the re-
ceiver LCD. Repeat sequence to unlock.
Optionally, the transmitter power switch can be remotely locked from the receiver front panel:
