Program LED lights activate, then go right out

202U model. I’m attempting to add remotes, but when I press to program, the LED lights up, then immediately goes out. Can’t program.

Please try following.

  1. use another 12vdc power adapter and try again.
  2. press & hold PRG1 or PRG2, then try program remote buttons.
    If still doesn’t work, it might be defective unit.

Is there a recommended amp rating for power adapter?

Any 12v adapter with > 0.5A current will work just fine.
