shows your starting location, present position, course line and destination.
Using the map is as simple as pressing the
PAGES
key. A screen similar to
those on the next page appears. The arrow flashing in the center of the screen
is your present position. It points in the direction you're traveling. The solid line
extending from the arrow is your plot trail, or path you've taken.
The map zoom range is the distance across the screen. This number shows in
the lower left corner of the screen. In the first example below left, the range is
4,000 miles from the left edge of the map to the right edge of the map.
The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its
coverage area and the amount of mapping detail shown. There are 37 available
map zoom ranges, from 0.05 miles to 4,000 miles.
