Inserting a chart
cartridge
The Navionics chart cartridge
must remain free from debris
and moisture at all times. To
ensure that you do not expose
the cartridge to any environ-
mental damage, please use
caution when changing the
cartridge. Exercise care when
inserting the cartridge into the
Northstar unit (see description
and illustration at right). When
not in use, store the cartridge
in a clean, dry place away
from heat, humidity, and dust.
Improper handling and stor-
age of the cartridge may result
in damage to the Northstar
unit. Such damage is not cov-
ered under manufacturer war-
ranty.

Before inserting the cartridge, make sure that the cartridge

below in Figure 1: "Proper insertion of a chart cartridge,"
below. Insert the cartridge gently but firmly into position with
one straight, smooth motion. If you partially insert the car-
tridge, stop, then move the cartridge again, it may become
stuck in an awkward position.
