958 Operator's Manual, Rev. A
To help protect the Nav-Chart cartridge (as well as the 958's
internal components) from water and salt spray, a switch in the
958's cartridge door latch senses if the door is open or closed.
When open, the 958 won't do the following:
•
use or display information from the chart cartridge
•
display the cartridge's ID name or date information on the
CHART SETUP/STATUS screen
Essentially, when the door is open the 958 acts like there's no
cartridge installed.
If the door becomes damaged, or the latch sensor doesn't work
properly, you can bypass the safety feature by pressing the
MORE key on the OPTIONS/SERVICE INFO screen, then the
IGNORE DOOR key on the MORE OPTIONS/SERVICE INFO
screen, then the ENTER key. The 958 will then let you use the
cartridge as if the door was functioning properly.
Leaving the cartridge door open may cause serious water
damage to the 958's internal components. If the door is
damaged, you should return the 958 to the factory for repair.
IGNORE DOOR
The
short-term emergencies when the door won't close properly.
The bypass stays in effect until you disable it or shut the 958
off. The next time you turn the 958 on, the IGNORE DOOR
command won't be in effect; you must re-invoke it by
re-pressing the IGNORE DOOR menu key.
This key is used for factory testing of the 958's screen, and
pressing it will display a blank screen. Press any function key
key
to return to another screen.
