Ocean, in a geo-stationary orbit over the equator. Effective use of the WAAS satellite signal can be limited by your geographic location in relation to those satellites, now in developmental service. WAAS satellite signal reception requires an absolute clear view of the sky and works best when there are no nearby obstructions such as buildings, mountains. WAAS satellites are numbered 33 or higher when viewing the sky view on your GPSMAP 198C Sounder. 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 198C Sounder 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. MAIN MENU > GPS TAB 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. GPSMAP 198C Sounder Owner's Manual 41
