Hi,
There have been a few issues with 302 flight log security failures this
year. Some of the failures can be avoided by making sure your 302 is
running the latest firmware (2.63) and by using the latest version of the
Cambridge 300 Utility (2.57) to download your flight logs to a PDA or PC.
Unfortunately, Cambridge has been unable to update the web page on which
they have their utilities. I have therefore made them available on my web
site he
http://www.cumulus-soaring.com/cai_downloads.htm
The 302 firmware file (version 2.63) has not changed in several years, but
the 300 Utility was updated only a few months ago to version 2.57 for PDAs
and version 2.56 for PCs.
The firmware version in the 302 is displayed at power-up on the LCD display
on the 302.
If you find that the 300 Utility shows that your flight log does not pass
the validity checks after download - please try again several times. That
will most likely solve the problem. If it does not solve the problem then
contact Gary Kammerer at Cambridge at
662) 280-7610. It is almost always
possible to get a valid flight log out of the 302 - assuming that the 302
shows that it is properly sealed.
Good Soaring,
