How do I search for the correct device code if I can't find my brand?

Turn on the device and press the matching device button on the remote. Press and hold SET until the LED flashes twice, then press 9-9-1 (the LED flashes twice). Point the remote at the device and alternate between pressing the POWER button and the device button until the device turns off. If the device still doesn't respond, clear the device button and repeat the search procedure.
