Menus
Most of the unit's features are found on "menus'. You can view the menus
by pressing the MENU key. This product has "Intelligent Menus". There
are many menus that pertain to only the map, for example. When you
press the MENU key and the plotter is showing, menu items for the plotter
show in addition to the normal menus. For example, if the navigation screen
is showing, and you press the MENU key, plotter menu items won't show
on the list. This helps you find the needed item without scrolling through
unnecessary menus.

Turning Power On

To turn the unit on, simply press the PWR key. A GPS
logo screen appears, then the screen similar to the one

then press the EXIT key to erase it or wait a few sec-
onds and it automatically clears. The satellite status
screen shown at the top of the next page appears next.

Satellite Status Screen

This screen shows a graphical view of the satellites that are in view. Each
satellite is shown on the circular chart relative to your position. The point
in the center of the chart is directly overhead. The small inner ring repre-
sents 45° above the horizon and the large ring represents the horizon.
North is at the top of the screen. You can use this to see which satellites
are obstructed by obstacles in your immediate area if you hold the unit
facing north.
