Use the RIGHT/LEFT arrows on the CURSOR KEY to ad-
just the contrast to a comfortable level, then press ENTER to
confirm.
Follow the instructions at the bottom of the screen, pressing
ESC twice to back out of the AUXILIARY screen.
Adjusting Backlighting
Adjust backlighting to three different levels of intensity by
pressing and releasing the PWR key repeatedly. The intensity
increases and decreases incrementally when the PWR key is
pressed.
First Time Use - Initializing the Receiver
The constellation of 24 GPS satellites circling the globe is in
constant motion and before your receiver can tell you where
you are, it needs to know where the satellites are relative to
itself. Your receiver’s internal almanac tells it which satellites
are in view at a given geographic position.
Therefore, you need to enter your approximate location, time
and date, which will serve as a point of reference for your
receiver in selecting the best satellites to use. Without know-
ing its approximate location, the receiver may take 10 min-
utes or more to find the specific coordinates of your position.
Telling your receiver the initial position, time and date is called
initializing your receiver; initializing enables it to begin track-
ing satellites, and therefore, calculating your position, much
faster.
You need not reinitialize your receiver each time
you use it, but only if the unit has moved over 300
miles without computing a postion or if the total
memory has been cleared by the user. If you do
not reinitialize, the receiver may take 10 minutes
or more to compute a new position fix.
Entering an Approximate Initial Position. To give your re-
ceiver an approximation of its current position, you will need
to enter the latitude and longitude of your general location.
The receiver allows you to enter the location quickly and
easily using the MAP screen.
While viewing the Satellite Status screen, press the INIT
POS softkey. The Map screen will appear.
Use the CURSOR KEY to move the cursor to your present
geographic area on this map. Use the ZOOM IN /ZOOM
OUT keys to help you determine whether the cursor is
active in the right part of the globe. (Some basic knowl-
edge of continental land masses is helpful.)
If the cursor is not in your region of the world, press ZOOM
OUT repeatedly, then use the CURSOR KEY to move the
cursor to your present geographic area and use the ZOOM
IN key repeatedly to zero in on your present location.
When you have placed the cursor near your current loca-
