If you have turned on GPS in the profile you chose, the
V650 automatically starts searching for the GPS satel-
lite signals.
Keep your V650 still with the display facing upwards
during the search. It typically takes 30-60 seconds the
first time. In future it should take only a few seconds.
The V650 is ready once the green circle around GPS is
static.
After finding the satellites, the V650 calibrates the
altitude. Altitude calibration complete tells you that
the calibration is ready. To make sure that the altitude
remains accurate, calibrate your V650 manually
whenever a reliable reference, such as a peak or a
topographic map, is available or when at sea level. To
calibrate manually, press the side button and choose
Calibrate altitude. Then, set the altitude of your cur-
rent location.
