Pete, I know I'm not going to satisfy your every need. First of all, it was:

"You haven't listened to it!"

then it was:

"You had your windows open!"

then it was:

"You didn't follow procedures properly!"

then it was:

"You didn't reactivate it!".

Well, I confess. I did fail in one respect  I did not incinerate it in the middle of a pentangle with a candle burning at each apex, and dance around it five times clockwise and then five times anticlockwise while reciting the appropriate verses from the Kabbala.I did this out of respect for Herr Baschung, because he wanted it back in perfect condition.

The instructions are at home, but I remember nothing about the unit requiring activation. I mean, you plug it in and you turn it on and you leave it. Is this activation an extrapolation of your own? Are you not going to tell me what it is, because it actually isn't there?
