You don't mention which remote you have. This information is for the Slimline 2:
Power sync your digital box and TV
- You can set up your digital box and TV to turn on with one button press. Press and hold the Options button for 3 seconds, until the green LED on the remote control flashes twice
- Enter code 0007 – The green LED will flash twice. The Optik power button will then turn on both your digital box and TV (It will also turn on your amplifier, if programmed). To turn power sync off, enter code 0006 and the green LED will flash twice
