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 135
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 135 Sounder's 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 135
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.
