WAAS satellite signal reception requires an absolute clear view of
the sky and works best when there are no nearby obstructions such as
buildings or mountains. WAAS satellites are numbered 33 or higher.
Initial reception of the WAAS signal may take up to 15-20 minutes.
When WAAS differential correction has been received for GPS
satellites (numbers 32 or below), a
D
appears in the signal bar of the
sky view and
2D
or
3D Differential
appears in the receiver status. To
learn more about the WAAS system, its satellite positions and current
state of development, visit the FAA Web site: http://gps.faa.gov.
Since WAAS requires CPU resources of the GPSMAP 176/176C to
search for and track the satellites, you may disable the WAAS feature
to improve unit performance if WAAS reception is not available in
your area. The unit does not search for WAAS satellites if the unit
is in Battery Saver mode. To disable/enable WAAS capability from
the System tab, highlight the
WAAS
field and press
ENTER
. Select
either
Enabled
or
Disabled
and press
ENTER
.
From the Main Menu
System
tab, highlight the
WAAS
field and press
ENTER
to
Enable
or
Disable
WAAS.
