How to program the x10 learning remote control without using device codes
Hold down the “Setup Button” until the red led light stays on.
Click one of the functions you want to use: IE: TV, VCR, CBL or, X-10 until light begins to blink.
Start clicking the CHAN +(UP) button until the channel changes. Once the channel changes you have found the code for that device, Click the ENT Button to save the code for that device.
To test it clicks the Power Off button for that device to turn off. If it turn off then you are done and Repeat these same steps to program your other devices such as your cable/box.
I hope this help you out.
