Answer 1

Try these codes 0019,0056,0060,0030,0178,0196

Manually turn on the component you want to program.

Hold the Device key down until the green indicator light comes on. Release the Device key. Within 30 seconds, enter in the code number. The light will flash when the right code has been entered.  Press the Power key. If the component turns off, you have found the right code.
