Questions & Answers

Units must be paired prior to use. This requires pressing and holding the Channel buttons on both the TX and the RX simultaneously for 5 seconds. The TX and RX must be powered to be paired.

If performing a factory reset (pressing and holding for 10 seconds) on the TX, RX, or both units, the units must be paired again to connect.

The default Channel out of the box is Channel 1. Before changing the Channel, make sure the TX and RX are paired.

To view the Channel of the TX or the RX, press the Channel button once on either unit. The Channel will display on the monitor of which the RX is connected.

It may be necessary to switch Channels if experiencing performance issues. As long as the units are already paired, they will not need to be paired again.
