Saving and restoring a 961/962 database
You can easily save, or backup, your 961/962's entire database of
user-defined waypoints and routes as well as your user preferences, to
either floppy or zip disks. (User preferences are the display, navigation,
chart, receiver, and port-setup features of your 961/962.) The 961/962 is
sold with a standard 1.44-MB floppy disk drive. If you want a larger
capacity, removable storage disk drive, you must order the 100-MB zip
drive to replace the standard floppy drive.
After saving, you can then restore these databases back to the same 961/
962. Why save and restore? One, you may want to keep a separate set of
waypoints and routes for one cruising area and another set of waypoints
and routes for another cruising area, and so forth, so that you don't have
to sort through one large database of waypoints and routes to select the
ones you want (even though the 961/962's search function is always
quick and easy). Two, if you ever have to return the 961/962 to the
factory for service, it's a good idea to have a separate copy of your
waypoints, routes, and user preferences from the system's hard drive,
since it's possible that this information may be lost during repair.
Restoring the database from one 961/962 processor onto
another 961/962 processor will OVERWRITE the existing
database of the first 961/962 processor.
A high-density IBM formatted floppy disk always has enough space to
store your backed-up databases (a zip disk also has enough space). If you
receive the message "Unable to copy data to the removable disk," the disk
could be write-protected: To change the write-protection status of a
floppy disk, use the tip of a pen to switch the position of the small square
on the outer corner of the disk.
The save-and-restore function isn't designed to be used for
your tracks, charts, alarm settings, or the trip. This data can't
be saved to either type of disk as described above.
