Speed Display If vehicle speed is not being recorded, set to
OFF. This turns off the 0 on the display, which
indicates zero speed.

input type to obtain the speed:
• a GPS receiver
• a pulse counting input
[Pulse], GPS, Off
Speed Units If the speed is being recorded from the GPS
receiver or the CAN network, the desired speed
display units must be selected. Selecting MPH
converts the GPS signal to display speed in
miles per hour.
[MPH], KPH, KTS
Speed Pulse Count The DVR records vehicle speed by counting the
number of pulses received either from a vehicle
speed sensor or a vehicle Transmission Control
Module (TCM). Calibrate the DVR to the
vehicle’s speed signal by driving for one mile in
Calibration Mode. The DVR counts the pulses
from the speed sensor and then converts a pulse
rate into speed. The actual distance driven
during calibration determines the unit of the
speed.
For example, to have speed recorded in MPH,
drive for one mile in Calibration Mode. To have
speed recorded in KPH, drive for one kilometer.
The SPEED PULSE COUNT increments as the
vehicle travels.

Calibrate When calibrating speed, it is best to use known
road markers to determine a mile, as reading the
odometer may introduce errors.
• Press ENTER to begin calibration.
• Press MENU to exit.
