3.3.4. "POSITION" menu, Set position
The position details of the weather station location are needed to calculate the
sunrise and sunset times. You can enter the latitude in a range between –60.0° and
+60.0° and the longitude between - 180.0° and + 180.0°.
You can determine your position in different ways:
- The Appendix B contains a table with the coordinates for many US counties.
You can select a place in your vicinity and then enter its coordinates
- If you have a GPS navigation system in the car or a mobile device you can
take over the position details and you will thus have the exact location.
- You can also find out the exact coordinates from the Internet.
- Select the "POSITION" menu:
NEXT POSITION ENTER
- Touch the "ENTER" field, the display is:
LATITUDE + 38.9 -
- Touch the "+" or "-" areas to set the latitude.
- Touch the "LATITUDE" field, the display is:
LONGITUDE + -77.0 -
- Touch the "+" or "-" areas to set the longitude.
- Wait a few seconds; you will then see the corrected day for sunrise and
sunset in the display.
Please note that the sunrise and sunset details will really be correct at the sea or for a
location on the plains. Mountains, high forests can really cut short the actual day.
The details can deviate slightly even for the ideal location because an
approximation formula is used for the calculations.
