SETUP MENUS
Sunrise/Sunset Planning and System Setup
The fuel and trip planning submenu also allows you to calculate the sunrise
and sunset times for your present position or any waypoint for a selected date.
To use the sunrise/sunset planner:
1. Highlight ‘Trip & Fuel Planning’ option from the main menu and press T.
2. Highlight the first waypoint field and press T. Press the left arrow key
to clear the field, and use the R keypad to enter the name of the desired
waypoint. You may leave the waypoint field blank to use your present
position, or press the O key to select the waypoint from the nearest list,
the waypoint list, or the map display. To calculate the sunrise/sunset for
your present position, leave both waypoint fields blank.
3. Press T to confirm.
4. Highlight the date field and press T.
5. Enter the date you want sunrise/sunset information for (current date and year
will be used as the default setting) and press T. The sunrise and sunset
times for arrival date will be displayed at bottom right of the planning page.
Setup Submenus
The last four options available from the main menu page provide access to
the various system, navigation, alarm and interface settings of the GPSMAP
175. The system setup submenu is used to select the operating mode, date
and time formats, tone preferences, backlight timeout and display contrast.
• Operational Mode lets you select between normal operation and
simulator mode. The GPSMAP 175’s system only pretends to track
satellites in simulator mode, and should not be used for actual
navigation. Waypoints and routes created in simulator mode are saved in
memory and are available for use in normal mode.
• Time Offset provides a data entry field to enter the time difference
between UTC time and the local time. (See Appendix E for a list of time
offsets.) When entering a time offset, be sure to select a positive or negative
offset. Note that entering an offset will not automatically display local time.
The local setting from the Date/Time Selection submenu must be selected.
