I just got a Home Theater Master MX-500 remote, so far the setup has been smooth, it's very easy to program, but I've run into one roadblock. In order to power-up my projector, you have to hold the power button down for about 3-4 seconds...but I can't figure out how to make the MX-500 send a command for that long. My one idea was to have the 'power-on' function learn to the 'channel-up' button on the MX-500, since the channel-up button should be able to send a continuous signal, but it didn't work. Does anyone know how to make this work? Thanks.
