Taken From A Board : Credits Go to Neromo.
Use your remote
Menu> System Info> Biss Menu
Scroll down to the bottom of your biss list to the next available line entry...could be say line 7 or 8 where they are all 000000?
Type in the HEX rai keys TWICE in the same line and press exit and YES to save this setting.
Switch the stb off/on and goto RAI Int or Africa 13e 10.992v 27500. You often may have to switch off/on the channel or switch STB off/on while on the channel for sound.
TIP: If you are watching say RAI Uno (or any other RAI channel) and go straight to RAI Inter/Africa it clears without the need to do the above..
Thats it . Hope this helps. RAI Inter/Africa transmits a lot of Italian Football...
Also :
After some more experimentation I've found that going to a particular channel and using your remote and key 8280 does open up the list on the correct line.
BISS /DCW keys are very shortlived ......
