Get the camera lens focused on the front and fix with Lock Screws of the
device.
GPS reception part should be exposed to the window for the better reception.
Connect the cigar jack to the power port and check if the power is working
properly.
 SD Card should be inserted before connecting the power. Otherwise,
Red and Green LED would be blinking at 0.5sec interval by turns.
Press “Down” for 3 seconds when power is on, and calibrate G-Sensor
value. (Check if Red LED is blinking at 0.1sec interval rapidly for a second.)
 When calibrates G-Sensor, put the device on flat place.
When changes the place to attach the device, calibrating should be done once again.
Play back the saved data after testing drive. Then, check if the
data is recorded correctly and revise the camera place on it.
JS-300/JS-300G is working based on High- Sensitivity Camera Sensor.
The recorded video image can be shown dark if the device is installed toward the sky.
If the camera angle is not proper, adjust with rotating the lock screw
and fix it after.
Refer to the steps 2 ~ 5.

JS-300G_v3.indd 19 2009-09-10 ¿ÀÈÄ 4:38:57
Insert SD Card into RVS-300 / RVS-300G, then power on. Red, Yellow and Blue
LED will light sequentially at a second interval.
About 3 seconds after lighting, RVS-300 / RVS-300G will start running.
If it powers on without SD Card, Red and Green LED will be blinking alternately at 0.5 sec interval. In
this case, disconnect the power and connect power again after inserting SD Card.
1.
Recording is run based on Event and Normal record mode (Full Time Mode), and the
present recording mode is saved and memorized into Configuration Variable
Setting File in SD Card.
(The Factory default record mode is Event Mode and it would be same after formatting SD Card.)
2.
To change the recording mode, connect power under the status of pressing
Emergency key simultaneously.
The mode will be changed either Event Record mode to Normal Record Mode or
Normal Record Mode to Event Record Mode.
The changed recording Mode would be saved into SD Card and maintained until
the mode is changed by user.
When pressing the Emergency Key, press until Red LED turns on.
2.
During Event Record Mode, Red LED is blinking at one second second intervals.
1.
When the impact value recognized by G-Sensor (acceleration sensor) is bigger than
user-defined value or when user presses Emergency key manually, the image and
voice before 10 seconds and after 20 seconds of the event will be saved as a file.
When an event occurs, Red LED will be blinking rapidly at 0.1 second
intervals for 3 seconds and inform of it.
2.
If another event occurs while the previous event is being saved, the second event
will be ignored.
(If emergency record is required, just press Emergency button and recording will be started. After
recording, the mode will be back to Event Record Mode.)
Event can be recorded up to 100 times as a file, and from the file recorded first it would be overwrit-
ten sequentially when the number of file is exceeding the maximum.
3.
When the power is disconnected on Event Record Mode, RVS-300 while recording
an event, it will shutdown after saving the event, maximum 20 seconds. Otherwise
it will shutdown instantly.
4.
`the Stop Key is pressed, RVS-300 / RVS-300G will complete recording the event
and all functions will be stopped. (All LED lights will be off.)
To start RVS-300 again, disconnect power and reconnect.

Green LED is blinking at a second interval on Normal Record Mode.
2. Normal Record Mode records video and audio at 5 minute interval successively.
1. 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.
2. 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 for one second.
3. 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.
4. If there is any substance which can give the bad effect to GPS reception, please
leave it in the distance from RVS-300.
3. If SD Card storage is full during Normal Mode, RVS-300 / RVS-300G will over-
write starting from the file saved first.
4. During Normal Mode, G-Sensor (Acceleration Sensor) and Emergency Key function
will be ignored.
5. If power is disconnected during Normal Mode, RVS-300 / RVS-300G will be
shutdown after 10 second additional recording.
If the STOP Key is pressed during Normal Record Mode, RVS-300 / RVS-300G
will complete recording and all functions will be stopped. (All LED light will be off).
To restart RVS-300, disconnect power and reconnect.

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,
