quencies.
Important! Before you begin:
Turn off all transmitters for the systems you are setting up. (This prevents them from interfering with the frequency scan.)
Turn onthefollowingpotentialsourcesofinterferencesotheyareoperatingastheywouldbeduringthepresentationorper
formance (the scan will detect and avoid any interference they generate).

Channel Scan
Channel scan automatically scans a group to find available frequencies.
From a selected channel menu: Channel Scan
To begin, use the control wheel to choose the group you'd like to scan.
Choose one of the following options:
Find Next: Finds the next available frequency within the group
Find Best: Finds the best available frequency based on RSSI
Press ENTER to confirm your frequency selection.
Group Scan
Group scan automatically finds all available frequencies within a group. Available frequencies can be automatically deployed to
receiver channels and other networked components.
From a selected channel: Group Scan.
Press Start to scan the group.
When the scan is complete, the number of frequencies found are shown on the display.
Select Deploy to assign frequencies to components on the network.
