If you can’t tune your TV in, or you need to change the default channel number the Sky box uses and also need to activate the 9 volts in the Sky menu you can check the RF output settings from a hidden menu option on your Sky box:
- Press ‘Services’ on the Sky remote, then type 4 0 1 and press ‘Select’ (HD boxes: ‘Services’ , 0 0 1 then ‘Select’)
- Select the “RF outlets” option
- Change the RF channel number to a number of your choosing (between 21 and 68) press the green button to save. It’s important not to clash with a TV service on the same number. If you find that one of your TV channels goes fuzzy, change the RF channel number again.
