Assuming that the device code for your Sony receiver is 0158, the advanced funcion code to select TV/SAT is 384. I programmed this code on to Button 3 of my One for All Cinema 7 remote. The RS15-1994 uses the same codes.

To program the advanced function code:

1. Press the desired device key, e.g.: AUX1 for the receiver using the RS15-1994.

2. Hold the "P" button until the remote blinks twice.

3. Tap the "P" button followd by the 3-digit code for your desired function, e.g.: 384

4. Press the button that you want to assign to this function, e.g.: 3.

Hope this helps,
