The GPSMAP 168 Sounder’s Status Page provides a visual reference of satellite acquisition, receiver
status, date, time and position coordinates. Each page of the GPSMAP 168 Sounder’s system also
features an options menu, giving you access to other functions and features related to the specifi c
page you are viewing. To get a feel for how the options menus work, let’s put the GPSMAP 168
Sounder into simulator mode.
To place the GPSMAP 168 Sounder in simulator mode:
1. From the Status Page, press the MENU key. A menu of options and functions for the Status Page
will appear.
2. Press UP or DOWN on the ARROW KEYPAD to highlight the ‘Start Simulator’ option and press
ENTER/MARK.
3. Press the ENTER/MARK key to confi rm the ‘Running Simulator’ message that appears at the
bottom of the display.
Once the simulator has been started, the status fi eld at the top of the page will display a ‘Simulating
Navigation’ status. Now you’re ready to continue the rest of the simulated tour.
The GPSMAP 168 Sounder does not track satellites in simulator mode, and this mode
should never be used for actual navigation.
All the waypoint and route planning done in simulator mode will still be retained in memory
for future use.
Press UP or DOWN on the ARROW
KEYPAD to move the backlighting
slider up for brighter or down for
dimmer backlighting..
When the unit is in simulator mode,
an ‘S’ will appear in the lower left
corner of every screen and the Status
Page will show “Simulating Naviga-
tion.”
