961/962 INSTALLATION MANUAL Revision A
Periodically, you may become aware of the release of a new version of
961/962 software. To request the current software update on a CD-ROM,
call the Northstar Service Department. Installation instructions are
provided with the CD; be sure to read and follow these instructions
carefully.
You must always install software that is the same as what
you have or newer. Installing older software will cause the
machine to fail,and you will lose your waypoints, routes, and
charts.
To ensure that you receive the correct CD-ROM, be sure to give the
Northstar service technician your current software version. To find the
version of your software, press the
MENU screen, then press the
version number is located in the PROCESSOR SN/REV field.
Before installing any software upgrade, be sure to save the
user's waypoints, routes, and user preferences to a floppy or
zip disk.
