• Time Offset: Provides a data entry field to enter the time difference between UTC
time and local time (see page 105 for a list of time offsets). When entering a time
offset, be sure to select a positive or negative offset. Entering an offset will not auto-
matically display local time. The local setting from the Date/Time Selection submenu
must be selected.
• Local/UTC: Lets you choose to display the date and time in UTC (also Greenwich
Mean Time) time or local time offset from UTC time. The default setting is local
with a ‘0’ offset. (If you are boating in the United States, be sure to enter a negative
time indicator in front of the appropriate time offset for your location).
• Tone Selection: Lets you select an audible tone for messages and keystroke confir-
mation (the default setting), messages only, or no sound at all. Caution: Setting
the tone selection for no sound will prevent an audible tone for all alarms, includ-
ing shallow water and proximity waypoints.
• Display Contrast: Provides a slide bar to adjust the LCD screen contrast in order
to compensate for changes in temperature or lighting conditions.
• Backlight Timeout: Provides an automatic shutoff for the sounder’s screen back-
lighting. Six settings are available: No Timeout (the backlight will stay on until it is
turned off), 15 seconds (default setting); 30 seconds; and 1, 2, or 4 minutes.
• Language: Allows you select from nine languages the unit can display. The avail-
able languages are English, Danish, Finnish, German, Italian, Portuguese, Spanish,
and Swedish.
The system setup page also features an options menu that allows you to quickly reset all
the system setup options to the factory default settings and define speed, course, and posi-
tion values while in simulator mode.
To view the system setup page options:
1. Press the O key.
To restore the default settings:

flashed on the status bar for any system messages
or alarms.
