Getting-Started Tour
Now that your GPS 40 has been initialized, it’s time to
take a tour through the it’s basic features and functions. The
tour assumes that you have initialized the receiver and have
not changed any of the factory settings (units of measure,
selectable fields, etc). If you have changed any of the
default settings, the pictures and descriptions may not
match your unit’s configuration.
Powering Up and Taking a Fix
Take the GPS 40 outside and find an open area where
the receiver will have a clear view of the sky. Hold the
receiver at a comfortable height, at arm’s length from your
body, with the internal antenna parallel to the ground.
To turn the unit on:
1. Press and hold
B
until the receiver turns on.
A 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 status page and the
GPS 40 will begin acquiring satellites.
Satellite Status Page
The GPS 40’s satellite status page provides a visual ref-
erence of satellite acquisition and position. As the receiver
locks onto satellites, a signal strength bar will appear for
each satellite in view, with the appropriate satellite number
(1-32) underneath each bar. The progress of satellite acqui-
sition is shown in three stages:
• No signal strength bars— the GPS 40 is looking
for the satellites indicated.
• Hollow signal strength bars— the GPS 40 has
found the satellite(s) and is collecting data.
• Solid signal strength bars— the GPS 40 has col-
lected the necessary data and the satellite(s) is
ready for use.
Note that each satellite has a 30-second data transmis-
sion that must be collected (hollow bar status) before the
satellite may be used for navigation (solid bar status). Once
a fix has been calculated, the GPS 40 can take on the easier
task of updating your position, track and speed by selecting
and using the best satellites in view.
