I have the full printed manual for the A640 and pages 30 & 31 do not refer to anything relevant to my problem. I can't find anything in the manual that is even vaguely helpful. I must have missed something.
Interested in your comment about ZB and how useful a card reader is. I'll bear it in mind meanwhile I'd liek to get the ZB working as it's intended to work.
Any further ideas?
There is 2 manual one basic and one advance. The page I'm referring to is in the basic.
