If GPS data is not received properly,
Blue LED
will blink at one second intervals. When
GPS Data reception is working properly,
Blue LED
will be lit continuously.
1.
If the Play Key is pressed during either Normal Record Mode or Event Record Mode for
more than 3 seconds, GPS Cold Start will be operated with
Blue LED
blinking rapidly at
0.1 second intervals for one second.
2.
If GPS Data reception is running correct, set the time of internal RTC
(Real Time Clock)
on
GPS time. Once set on GPS time, it will maintain the exact time without any additional
time set. The internal RTC time is reflected with connecting the power again after power
disconnection.
If a vehicle is parked on a flat plane, G-Sensor data should have a value of
X = 0g, Y = 0g and Z = +1g. However, it would be changed by the place RVS-300/RVS-
300G is placed and mounted. Thus G-Sensor should be calibrated to get more exact
data
G-Sensor Calibration must be done on a flat plane after parking.
3.
If there is any substance which can give interfere with the GPS reception, please leave it
at a distance from RVS-300.
4.
If the Down Key is pressed during either Normal Record Mode or Event Record Mode
for more than 3 seconds, Calibration will be operated with Red LED blinking rapidly at
0.1 second intervals for one second.
After the calibration, G-Sensor Data will show a value of:
X = 0g, Y = 0g and Z = +1g, regardless of the mounting place.
2.
G-Sensor
(Acceleration Sensor)
shows the Acceleration Value of
X, Y and Z axis on the unit of acceleration of gravity,
1g = 9.8m/s2. And the directions are as below image.
