GPS DISPLAY When GPS DISPLAY is ON and a GPS receiver is connected to
the DVR, the latitude and longitude of the vehicle location are
displayed on the screen.

GPS
TIME A very accurate time source is embedded in the GPS satellite
signal. Set the
GPS TIME to ON to synchronize the DVR’S
internal clock to the GPS satellite time. Because the GPS
satellites do not know where the GPS receiver is, the GPS
signal sends Universal time, or
UTC time (also known as
Universal Time Coordinated.)
ON, OFF OFF
UTC
TIME REF UTC is referenced to the atomic clock standard in Greenwich,
England. The
DVR location is a certain time difference from
UTC time. For example, Eastern Standard Time is –5 hours
from
UTC time. Pacific Standard Time is –8 hours from UTC
time.
To use
GPS time, determine your time difference from UTC
time and enter this time into the
DVR. Use the time reference to
standard time. The
DVR keeps track of the Daylight Saving
Time changes internally (if auto daylight saving is set to on).

SPEED DISPLAY If speed is not being recorded, change the speed display option
to
OFF. This turns off the 0 on the display which indicates zero
speed.
If speed is being recorded, there are three sources that the
DVR
can use to obtain vehicle speed:
• a pulse counting input
•a
GPS receiver
•vehicle
CAN network.
Set the speed display option to the desired input type. All of
the speed input devices are optional. Contact your sales
representative at Seon Design to obtain the optimal speed
solution.

SPEED
UNIT If Speed is being recorded from the GPS receiver or the CAN
network, then the desired speed display units must be selected.
Selecting the speed unit to be
MPH makes the DVR convert the
GPS signal to display speed in miles per hour.
If the speed display is set to pulse, the speed unit does not
matter as the calibration routine automatically sets the unit.
