WAAS satellites are numbered 33 or higher when viewing the sky
view on your GPSMAP 192C. Initial reception of the WAAS signal
can take up to 15-20 minutes, then 1-2 minutes afterwards. 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 192C to search for and track the satellites, you can
disable the WAAS feature to improve unit performance if WAAS
reception is not available in your area. Refer to the “Appendix” for
more information.
To Disable/Enable WAAS capability:
1. From the
GPS tab, press MENU.
2. Use the
ROCKER to highlight WAAS Off or WAAS On, and
press
ENTER.
Highlight WAAS Off, and press ENTER
to disable the WAAS capabilities.
