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 180. The
system setup submenu is used to select the operating mode, date and time for-
mats, tone preferences, backlight timeout, and display contrast.
Operational Mode lets you select between normal operation and simulator mode.
The GPSMAP 180s 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 F for a list of time offsets.) When entering a
time offset, be sure to select a positive or negative offset. Note that entering an off-
set will not automatically display local time. The local setting from the Date/Time
Selection submenu must be selected.
