1.2 Loading a Mini Chart Card
Your unit reads FURUNO and NavCharts (NAVIONICS) chart cards, or C-MAP
chart cards, depending on the type of display unit you have. Insert the
appropriate chart card for your area before turning the power on to show chart
data automatically.
Note: Static electricity can be passed through your fingers to a card and destroy
the contents of the card. To prevent this, always touch a metallic object,
such as a steel desk, before handling a memory card.

This equipment takes about 90 seconds to find its position when turned on for
the very first time. Thereafter it takes about 12 seconds to find position each time
the power is turned on. The message "NO FIX", which means the equipment is
now findings its position, appears at the bottom of the Plotter (or Pilot) display
immediately after turning the power on. When the GPS receiver finds its position,
"NO FIX" changes to "2D" or "3D" to show that position data is now accurate.
