Garmin GPS 92 - Manual (Page 13)

Once the GPS 92 has calculated a position fix, you’ll
usually have anywhere from five to twelve satellites in
view. The receiver will then continuously select the best
satellites in view to update your position. If some of the
satellites get blocked, or “shaded,” the receiver can sim-
ply use an alternate satellite to maintain the position fix.
Although a GPS receiver needs four satellites to provide a
three-dimensional (3D) fix, it can maintain a two-dimen-
sional (2D) fix with only three satellites. A three-dimen-
sional fix means the unit knows its latitude, longitude
and altitude, while a two-dimensional fix means the unit
knows only its latitude and longitude.
Initializing Your GPS 92
To initialize the GPS 92, take the receiver outside and
find an open area where the antenna has a clear view of
the sky. You may either hold the receiver at a comfortable
height with the antenna pointing up, or mount the
receiver’s antenna on the glareshield and taxi to a clear,
unobstructed area.
To turn the GPS 92 on, press and hold the red
B
key.
The Welcome Page will be displayed while the unit
conducts a self test. Once testing is complete, the
Welcome Page is replaced by the Database Page (which
shows the effective date for the Jeppesen database), then
by the Status Page.
EZinit
Your GPS 92 is shipped from the factory to display the
“EZ init” initialization prompt when first used. After a few
seconds, the EZinit prompt will appear on the Status Page
allowing you to select one of two initialization methods:
• Select Country— allows you to initialize the receiv-
er by selecting your present position from a list of
countries in the GPS 92’s internal database. This
feature provides a position fix in 2-3 minutes.
• AutoLocate— allows the GPS 92 to initialize itself
and calculate a position fix without knowing your
present position. This feature provides a position
fix in approximately 5 minutes.
The Database Page shows
the effective date for the
Jeppesen database and cov-
erage area. Updates are
available from GARMIN or
Jeppesen on a one-time or
subscription basis.
The EZinit prompt will
automatically appear if the
receiver needs to be initial-
ized. The prompt may also
appear during normal use if
the antenna is shaded or the
unit is indoors.
