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 185
Sounder. 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, simulator, sounder only, or GPS
only mode. In normal mode both GPS and sounder functions operate at the same
time. In simulator mode, the GPSMAP 185 Sounders system only pretends to track
satellites to allow you to learn how the unit works. Simulator mode 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. The sounder only and GPS
only modes allow you to determine what type of information the GPSMAP 185
Sounder will give you. GPS only mode is useful when using the unit for land navigation
while enroute to the water. Sounder only mode is an option if you do not want GPS
information (such as position, speed, heading, and map functions) while on the water.
