- 13 -
8-3. Start
1. Insert SD Card into JS-300G, then power on. Red, Yellow and Blue LED will light sequentially
at a second interval. about 3 seconds after lighting, JS-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.
2. 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.)
3. 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 press Emergency Key, just press it until Red LED turns on.
8-4. Event Record Mode
1. During Event Record Mode, Red LED is blinking at a second interval.
2. 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 interval for 3 second and
inform of it.
3. Another event occurs while the previous event is saved, the event would 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 over
written sequentially when the number of file is exceeding the maximum.
4. When the power is disconnected on Event Record Mode, JS-300G would be shutdown after saving
the event, maximum 20 seconds, if it is on recording an event. Otherwise it will be shutdown
instantly.
5. If presses Stop Key, JS-300G will complete recording event and all functions will be stopped. (All
LED lights will be off) to start JS-300G again, disconnect power and connect again.
- 14 -
8-5. Normal Record Mode (Full Time Recording)
1. 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.
3. If SD Card storage is full during Normal Mode, JS-300G will overwrite 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, JS-300G will be shutdown after 10 second
additional recording. If presses STOP Key on Normal Record Mode, JS-300G will complete
recording and all functions will be stopped. (All LED light will be off). To start JS-300G again, disconnect
power and connect again.
8-6. Reset
1. There can be unexpected system errors. If the error occurs, Green and Red LED light columns are on
at the same time and lighting on Orange color continuously.
2. When system error occurs, disconnect power. Then press Reset key with the pointed stuff such as a pin,
a ballpoint pen…etc., and connect power again. JS-300G will be re-booting and run.
8-7. GPS Functions
1. If GPS data is not received properly, Blue LED will blink at a second interval. When GPS Data
reception is working properly, Blue LED will be lighting continuously.
2. If presses Play Key on 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 a
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 JS-300G
8-8. Acceleration Calibration Function
z 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.
If a vehicle is parked on the flat place, G-Sensor data is supposed to have the value of X = 0g,
Y = 0g and Z = +1g. However, it would be changed by the place JS-300G is placed and
mounted. Thus G-Sensor should be calibrated to get more exact data.
- 15 -
z If presses Down Key on 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 for a
second.
After the calibration, G-Sensor Data will show the value, X = 0g, Y = 0g and Z = +1g,
regardless of the mounting place.
 G-Sensor Calibration must be done on the flat place after parking.
G- Sensor Data Analysis (Example)
Viewer Program shows G-Sensor Data Graph as the below images upon Log Data which is saved
with video files and driving status can be analyzed through the graph.
