Packing List
Attentions
The following use environments can cause Corner and front Radar detection instability:
- The things of small diameter, like pipe, wire … etc.
- The material can absorb the radar wave, like cotton, sweater … etc.
- Non-reflectional surface.
- Drives on grass road or rough road.
- Something sticks on sensor’s surface.
Alert Range
Through installing 2pcs of 79G radar sensors on the corner of car front
bumper, the buzzer is beeping to remind the driver once any object get closed
to the front bumper zone when the car is moving.
Application related:
Bumper properties, installation positions of the sensors, and surroundings
including from various types of ground surfaces may affect the ability of the
sensors to correctly detect obstacles. For example: (a). If the vehicle was
under an extreme heavy load, a ditch cover or large reflection on the ground
might cause false alarm at a larger distance from the vehicle.
CAUTION:
The Corner and front Radar system is strictly a driver assistant device. It
should not be considered as a safety device for any purpose. Manufacturers and
distributors of the product do not guarantee or assume liability for
collisions or damages that take place during vehicle driving.
Problem-solving
Installation
Installation of Radar Sensor
- Before attaching the sensors onto the bumper, please make sure the surface of the bumper inner is clean and smooth. Dented or scratched surface could degrade the radar performance.
- To keep the outside of bumper cleaning at all the time, especially the position of the radar sensors. In order to make the radar function be normal, please avoid the situation to be happened, for example, dirt, clay, snow, stickers(including transparent stickers), or other items covering the radars.
- If the bumper was impacted, please check the sensor positions, the shape of the bumper and stability. Once there is any visible offset from original installation position, it should be calibration performed.
- If the bumper was re-painted, the installation calibration should be performed.
- The radar sensors should be installed at the same height level as the targets to be detected.
- The mounting horizontal position should be 50~70cm(+/-10cm) height from the ground (depending on car type).
- The mounting Vertical position must be between 50~60cm(+/-10cm) height from the ground (depending on car type).
The installation spec and tolerance
| Item | Spec |
|---|---|
| Sensor to sensor distance | 100~140cm |
| Installation tolerance | +/- 10cm |
Note: The ground clutter caused by various car bumpers and different
fields is possible, so the realistic installation height and angle tuning
depend on the real case. 
-
The suitable installation position of 2 sensors on the front bumper.
Step1: To attach the sensor and bumper seamlessly.
Step2: glue the “K-520 Primer Adhesion promoter” as figure shown to strengthen the attachment. -
To install buzzer on car A-pillar and power function button on the dashboard.
-
To connect 12V/GND power to car power system.
-
To do sensors BGC calibration at first installation. (please refer to BGC Calibration step)
BGC Calibration step (after installation)
Step 1: Finish the installation and make sure the front bumper is fixed completely. (Refer to Picture1)
Step 2: To check the power is on and moving objects are >1 m away from sensors. (Refer to Picture2).
Step 3: To press the BGC button for more than 3secs to trigger the BGC Continuous beeps!!! (Refer to Picture3).
Step 4: To release the BGC button
- Before BGC: hear 3secs rapid beeps!
- After BGC: 2secs continuous beeps!
Note: the 3secs and 2secs are variable parameters.
Step 5: To check if the sensor function is normal or not.
Step 6: After finishing the calibration process, please remove the BGC
button cable.
