4.2.2 Setting the Position Data
This function serves to enter the geographical position of the system. This function is helpful for
the first installation but not necessary; it shortens the re-initialisation of the GPS-receiver. The
following dialogue appears after menu point 2 of the initialising menu has been selected:
set position data:
actual geographical latitude: (+ means north, - means south)
degree (+89 to -89)
=
+51
degree (0 to 59)
=
12
actual geographical longitude: (+ means east, - means west)
degree (+179 to -179)
=
+007
degree (0 to 59)
=
39
All entries are taken over by the entry key.
Latitudes and longitudes are entered in degrees and minutes. The entry must include the sign.:
Latitude: +
northern hemisphere
Longitude:
+
east 0°
–
southern hemisphere
-
west 0°
Once the entry is complete the data are checked and transferred to the clock. A reset will be re-
leased in the clock so that the reception process can start with the new data.
After the successful transfer the following message appears:
transfer position data latitude = : 51:12
transfer position data longitude = : 7:34
ready !, end by key ...
For a faster synchronisation the GPS-receiver only needs the entry of a rough position. For the
above example the following entry would suffice.
+ 50°00
+ 007°00
4.2.3 Setting the Difference Local/UTC
The difference between local time and UTC is entered under point 3 in the initialising menu.
The entered value refers to the difference between UTC and local ST-time (ST=standard).
As the local ST-time does not have a summer / daylight saving time changeover the difference
between UTC and local ST-time stays constant.
The difference between UTC and local time (with summer / daylight saving time changeover) is
calculated by the clock board depending on the entered changeover points of time.
The difference time is requested in hours and minutes, the hours being entered with sign.
+
for time zones east of the longitude 0°
–
for time zones west of the longitude 0°
