If using a chart cartridge, you should insert the cartridge before turning the
unit on (to avoid any possibility of a system lock-up). The cartridge slot is
cartridge
located at the lower right-hand corner of the unit. If the unit is off, you
can verify whether a cartridge has already been installed by opening the
cartridge access door (turn its handle ¼-turn counter-clockwise) and
looking inside the slot. If the unit is on, you can verify whether a car-
tridge has already been installed by pressing the &+$57 6(783 menu
key to the right of the CHART screen (the cartridge access door must be
fully closed and latched to display this information). One of two possible
screens will be displayed:
•
If a cartridge is present, the cartridge name and date are displayed at
the bottom of the CHART SETUP/STATUS screen (at left below).
• If a cartridge is either not installed or incorrectly installed, the words
NONE INSERTED are displayed (at right below).
The cartridge name is derived from its Navionics catalog number. The
date may not be present for all cartridges, especially older ones; in these
cases, the word PRESENT is displayed in place of the cartridge name and
date.
Before inserting the cartridge, make sure that its label is facing up and
that the cartridge is oriented as shown in Figure 19 below. Insert the car-
tridge gently but firmly into position with one straight, smooth motion. If
you partially insert the cartridge, then move the cartridge again after
stopping, it may become stuck in an awkward position.
