Thanks Darryl,
I will post the file on the OLC when I get home from work this
afternoon, and email it to you.

The file looks complete in See You. The CAI utility did not complain
about it's integrity.

We also wondered about the internal battery in the 302, but after
checking the manual I
cannot even find any suggestion that one exists. I know that the
earlier Cambridge models
had them. The manual states " Flash memory is used for firmware as
well as flight logs. "

Regards, Bernie.
