Before You Initialize
Take the GPS 38 outside and find a large, open area (try
a nearby park) that has a clear view of the sky from horizon
to horizon. Hold the receiver at a comfortable height, at
arm’s length from your body with the built-in antenna (the
top part above the display) parallel to the ground.
Do your best to stay away from buildings or other
structures that could block the path of signals to the
receiver. GPS signals do not travel through rocks,
mountains, buildings, metal surfaces or other signifi-
cant structures.
To turn the GPS 38 on:
1. Hold the unit so the built-in antenna (the flat area above
the display) is parallel to the ground.
2. Press and hold
B
until the receiver turns on.
The welcome page will be displayed while the unit con-
ducts a self test. Once testing is complete, the welcome
page will be replaced by the Satellite Page, with the EZinit
prompt ready for you to select one of two initialization
methods:
• Select Country— allows you to initialize the receiver
by selecting your present position from a list of coun-
tries in the GPS 38’s internal database. Usually pro-
vides a position fix in a few minutes.
• AutoLocate
TM
— allows the GPS 38 to initialize itself
and calculate a position fix without knowing your
present position. Usually provides a position fix in
7.5-15 minutes.
If the EZinit prompt has not automatically appeared
on the Satellite Page:
1. Press the
E
key.
If you’ve already initialized the GPS 38 and the EZinit
prompt appears, highlight the ‘NO RE-INIT’ selection with
the arrow keypad and press
E
. The EZinit prompt may
appear if you’ve had the unit on in normal mode while
indoors, or if the antenna is shaded while acquiring satel-
lites in normal or battery saver mode.
Hold the receiver so the
built-in antenna is parallel
to the ground.
