VC4000 Manual
15
Do not use this unit in violation of federal, state or local laws. For
safety reasons the driver should never press any keys on the
VC4000 while the vehicle is in motion. If observation and operation
of the VC4000 is required from a moving vehicle, use a separate
observer/passenger. Please buckle up and drive safely.
Mounting
The VC4000 does not have to be level to get accurate results. It
uses a 3 axis accelerometer and calculates the
vector sum
of all 3
axe
s to calculate G force, speed and distance. G “Summation 3D
(XYZ)” must be on in Setup. It is
on
by default. See page 76 for
details. Mount the VC4000 so the display is roughly facing the back
of the vehicle, or so the x-axis is roughly along the front to back line
of the vehicle.

Alternatively mount the VC4000 flat and level using the single
suction cup mount or the dual bracket option with two pump-up
suction cups.
