The GPSMAP 135 Sounder’s status page provides a visual reference of satellite
acquisition and receiver status, with a signal strength bar graph and a satellite sky
view in the center of the page. Each page of the GPSMAP 135 Sounder’s system
also features an options page, which gives you access to other functions and fea-
tures that relate to the specific page you are viewing. To get a feel for how the
options pages work, let’s put the GPSMAP 135 Sounder into simulator mode.
To place the GPSMAP 135 Sounder in simulator mode:
1. From the status page, press the
O
key. The options page will appear, displaying a menu
of options and functions for the status page.
2. Use the UP or DOWN arrow of the
R
keypad to highlight the ‘Start Simulator?’ option and
press
T
.
3. Press the
T
key to confirm the simulator warning.
Once the simulator has been started, the status field at the top of the page will
display a ‘Simulating Navigation’ status. Now you’re ready to continue the rest of
the tour. Keep in mind that the GPSMAP 135 Sounder does not track satellites in
simulator mode, and this mode should never be used for actual navigation or to
determine the water depth. All the waypoint and route planning done in simulator
mode will still be retained in memory for future use.
