NOTE:

To perform an accurate calculation, Starfinder must be properly

initialized with the current date, time, and location of the observing site.

To enter the current date, time, and location information of your observing
site, see “ INITIALIZE STARFINDER” page 17, before proceeding with this
exercise.

To Calculate Sunset time:

1. Press the MODE key several times, until "Select Item: Object" displays.

2. Press the Scroll Down key once to display the Event option in the Select Item

menu.

3. Press the ENTER key to choose the Event option and move down a menu level.

"Event: Sunrise" displays.

4. Press the Scroll Down key once to display the Sunset option in the Event menu.

5. Press the ENTER key to choose the Sunset option and move down another menu

level.

6. Starfinder calculates the Sunset time based on the current date, time, and

location. Starfinder then displays the time of Sunset.

7. Press MODE once to start moving back up through the Starfinder menu levels.

The first menu level up is Event.

8. Press MODE again to move up another menu level. This is the top menu level,

Select Item.

9. Press MODE again to return to the starting point of "Select Item: Object."
