Figure 13: Properly inserting a chart cartridge
The Navionics chart
cartridge must stay free
from debris and
moisture at all times. To
ensure that you don’t
expose the cartridge to
any environmental
damage, please use
caution when changing
the cartridge. Be careful
when inserting the
cartridge into the 957
(see description above
and illustration at right).
When you’re not using
the cartridge, store it in
a clean, dry place away
from heat, humidity,
and dust. Improper
handling and storage of
the cartridge may
damage the 957. Such
damage isn’t covered
under the 957 warranty.
