Coldstart
If the VBOX LapTimer is struggling to acquire satellite
lock, you may need to do a GPS coldstart. This may be
necessary if you have not used the unit for a number of
days or it has dramatically moved location since the last
use.
Select MENU > GPS OPTIONS > COLDSTART.
GNSS Mode
The GNSS Mode is the satellite constellations that you
want to use. You have the following options:
• GPS + GLONASS
• GPS + SBAS (default)
• GPS + BeiDou
Back
Select Back to save your selection and go back to the
GNSS menu.
Leap Seconds
The number of leap seconds in this setting sets the
current offset between GPS and UTC time. This is set by
official bodies to compensate for the slowing of the
rotation of the earth. A new leap second is usually
introduced every 4 to 7 years. The last leap second was
added in December 2016. The current offset is 18
seconds - click here for more details.
