Racelogic VBOX LapTimer User Manual page 37

If you pull away before number 1 is displayed on the
screen, nothing will change. During or after number 1 is
displayed, the lap time measurement will start if you pull
away. If a lap had been running up to this point, that time
will be discarded.
After it has detected correct movement and a one-shot
start has begun, you cannot trigger a normal start/finish
line for 3 seconds.
This is disabled by default.
Gate Width
Press the square button to change the gate width. You
will see two arrows (up and down) appear next to the
number. Use the two arrow buttons on the device to
increase/decrease the width of the gate. Press the
square button again to confirm your selected distance.
The default width is 25 m.
Back
Press the square button with this line highlighted to exit
the Lap Timing Menu and go back to the main menu.
