5.8G/ 5.2G RF Pairing and LED Status:
Pairing:
1. Ensure the transmitter and receiver LED colors are the same. Long press the “pairing” button for 3
seconds on both units to enter pairing mode. The 5.8G or 5.2G LEDs will blink quickly once in pairing
mode.
Note: Pairing mode period lasts 20 seconds in case both units are not side by side and buttons are not
able to be pushed simultaneously. After 20 seconds, the “pairing” button will need to be pressed and held
again to enter pairing mode.
2. Successful pairing is indicated by a solid blue or green LED (depending on which GHz signal is selected)
on both the transmitter and receiver.
Note: The transmitter and receiver should be paired automatically out of the box using 5.8GHz by default.
