If the RIGHT/LEFT ARROW is inverted, the
highlight bar will move from right to left.
When the edit arrow icons appear on a screen that is not a menu, the arrows will
enter data and move the cursor.
Use the UP/DOWN ARROW to step through
letters and numbers or numbers only at the
cursor location. The RIGHT/LEFT ARROW will
move the cursor right or left one space.
To save the information you have selected or entered, press ENTER. The receiver will
automatically move the highlight to the next item in the menu, or move the cursor to
the next line.
Help screens aren't available for the SETUP and AUX menus. To exit these
features, just press any function key.
The Status Line. Most screens have a status line at the bottom of the display. (lt does
not appear on the help screens.) The status line provides information about the status
of the location fixes being computed, the power supply, which arrow keys are active,
and which arrow keys are in the Edit Mode.
We've already discussed the arrow icons, which appear in the far right of the status
line. The number of satellites being used to compute the current location fix appears
on the left. Between the number of satellites and the arrow icons, several other icons
or messages may appear.
