satellites. Further, comply with point 5 "General information regarding GPS
reception" from the operating instructions.
What does "
GPS lost" display mean?
"GPS lost" display on the screen of the GPS watch means that it does not
receive GPS signal or all the signals from the satellites were lost. For this, see
point 6.3.3. "Training" of the operating instructions.
Why can’t I see on the display?
Why doesn’t the display light work?
Check if the accumulators are charged and charge them if needed. However,
if no display appears on the screen, please contact the service.
Why is the screen black and why aren’t the displays readable?
T
his is caused by long exposure to sunbeams or too high environmental
temperature. Let the GPS-watch cool down, then the display will become
readable again.
The display on the sc
reen reacts slowly, why?
Is the temperature below 0°C? When the temperature rises again over 0°C,
the display will become normal. The saved data will not be lost.
How long does the accumulator of the GPS watch last?
The service life of the accumulator is of 14 hours, when using the GPS, and of
approx. 1 year in time mode.
It doesn’t show my current speed, wh
y?
Check if you receive enough GPS signal.
Why does the GPS watch show a certain speed, if I do not walk/I am not on
the move?
This depends on the exactness of position determination, measurement
intervals of the GPS respectively. See next paragraph, the exactness of the
GPS watch respectively.
