Sync from receiver to transmitter:
Perform a scan on the receiver (see "Scanning for the Best Open Channel" for best practices).
Align the IR windows on the receiver and transmitter. The windows should be 6-11 cm apart.
Press the SYNC button on the transmitter while the blue RF LED on the receiver is flashing.
The Transmitter displays SYNC when the sync is successful. The arrow between Rx (receiver) and Tx (transmitter)
shows the direction of the sync.
Note: When the RF LED on the receiver is flashing after performing a scan, the receiver sends its frequency setting to the transmitter. After it stops
flashing, pressing SYNC sends the frequency setting from the transmitter to the receiver.
Single Transmitter and Multiple Receivers
The following sync procedure should be used with a setup that consists of a single transmitter with multiple receivers, or if a
specific group/channel setting has been assigned to the transmitter prior to a performance.
Sync from transmitter to receivers:
Sync the first receiver to the transmitter using the sync procedure for a single receiver. Performing a scan and using the
resulting group and channel from the receiver is recommended.
Set additional receivers to the transmitter frequency (one at a time) using IR sync:
Align the IR windows on the receiver and transmitter and press SYNC.
The receiver LED should not be flashing when pressing SYNC.
Note: Receivers can also be manually tuned to the transmitter if an IR sync is not practical.
Multiple Transmitters and Multiple Receivers
Set up the first transmitter and all associated receivers according to the appropriate sync procedure. Keep the transmit
ter and all receivers from this first system powered on when setting up additional systems.
Set up each additional system using the appropriate sync process. Always leave each new system on before setting up
an additional one.
