Celes (Celestial) Tab— displays celestial data for sun and moon rise/set, moon phase, and
approximate skyview location of the sun and moon. The moon phase will display the current visible
portion of the moon as a light color. You may display this data for your current position, a position
from the map, or a waypoint location. Also, you may select a different date and time, or use the
current data.
To choose a position:

2. Select from ‘Current Location’, ‘Other Location’, or one of the available catagories. The catagories
available will vary depending on the MapSource data that is currently loaded in the unit.

location. If ‘Other Location’ is selected, a map will be displayed allowing a location to be selected using
the cursor. The location the unit is using will appear in the Date/Time/Position fi eld. The timetables
displayed will be based upon your current time zone. When using a position from another location
outside of your time zone, you will need to set the Time Zone for that location under the ‘Time’ tab on
the Main Menu (see page 72).
