Please note everyone - I have read the manual! the manual tells me to use a handset to reset either a phone or the base station! None of my phones are registered to the base station so i dont have a phone capable of talking to the bases - I cant register any phone to the base because the system pin is not known!

So, how do I reset the base back to the factory defaults!

Yes I have been through the manual. When it asks for my PIN I put 0000 but that is rejected. I can not go further.
