Automatic Time Determination by GLONASS/GPS
Symptom
Possible Reason and Troubleshooting Method
The clock does not
determine the time by
the satellites
–
satellite loss
indication is on.
•
For some time put the clock in a location with a better
satellite reception level, wait until the time is determined
and then relocate the clock to the initial position.
•
Restart the clock by switching the power supply on and
off.
The time was not
determined within one
hour after the start.
•
You selected the bad place for the clock installation, try
to find the place with a better satellite reception.
•
If it is impossible to select another location, wait for
another 12 hours. This is the time of the GLONASS/GPS
system satellites orbit around the Earth. It is possible
that the time will be determined at a certain satellites
position.
The time was not
identified in the
selected location
even after 12 hours.
•
The receiver sensitivity in the satellite tracking mode is a
lot higher than in the search mode. Put the clock in a
location with a good signal level for some time, wait until
the time has been determined, and then relocate the
clock to the initial position.
•
May be there is a metal barrier between the clock and
the window. Remove it to improve the satellite signal
reception.
•
If the toner film is pasted onto the windows remove it to
improve the satellite signal reception.
•
The satellite signal is not received in this location. The
synchronization with the exact time system is not
accessible. Set the time in manual mode (see Section 5.1).
