Do you really mean "no signal areas",in this case the digibox will look for the default transponder,if it canot find the main transponder,and the card should authorise ok.One more thing,I authorised a card in the uk but i had to unplug it before the BBC came on,two days later i plugged it in here in spain and after two more days BBC chanels loaded,so it seems if you miss it the first time, the switch on codes come round again,but for how long is anybodys guess...............brian
