"POSITION" menu, setting the position

Position data for the location of the weather station is required in order to calculate the
sunrise and sunset times. Latitudes can be entered in the range –60.0° to +60.0°.
You can determine your position in various ways:
- The Appendix contains a table listing the coordinates of many German cities. You can
use it to select a location nearby and enter the appropriate coordinates.
- If you have access to an in-car or a mobile GPS navigation device, for example, you
can use that to check your position data; this will give you your precise location.
- You can also find precise coordinates on the Internet, as there are many sites to do
with navigation.
- Select the "POSITION" menu:
NEXT POSITION
- Touch "ENTER" and the following appears:
LATITUDE
- Touch "+" or "-" to set the latitude.
- T ouch "LATITUDE" and the following appears:
LONGITUDE
- Touch "+" or "-" to set the longitude.
- Wait for a few seconds. The adjusted sunrise and sunset times will then appear on the
display.
Please note that the sunrise and sunset times will only be strictly accurate at
the coast or for a location with a completely flat landscape. In practice, moun-
tains, forests of very tall trees, etc. can considerably shorten daylight hours.
The times specified may even be a few minutes out if the location is an ideal one, as an
approximate formula is used in the calculation.
