TIME ZONE
a) When the unit completes calculating a location successfully, using the distance
from three satellites, the time is displayed. Since it cannot perform another
calculation immediately after it has completed on calculation, this indication
stops at that time.
When the unit can start another calculation, the indication starts advancing from
that time. When a calculation is done correctly, the CALC time is later than the
REAL time by 1 second.
Note
The same time as the REAL time is displayed as the CALC time during play
back.
