Additional remote fob for the 2CH-REM System
To program more remotes you press and hold the button on the circuit board, you will have to open the case first. Hold the button for a few seconds until the red LED flashes. Then press any button on each of the remotes you want to program, 1 at a time, so if you have 4 remotes you need to program all the remotes, even if they were already programmed, and just press any one of the buttons on each remote. Then remove the power from the receiver and plug it back in again. Now all remotes should work with the receiver.
