FAQ

Q: Rapid acceleration and deceleration alarm
When the vehicle speed increases rapidly due to sudden accelerator pedaling, or decreases rapidly due to emergency braking, the device can report the rapid acceleration and deceleration alarm information via SMS and phone call. The center number needs to be set. The default detection time is 3S, the range can be set from 1 to 30s, and the speed change can be set from 10 to 255km/h.
 
Q: Sharp turn alarm
When the vehicle makes a sharp turn during driving, the device can report the sharp turn alarm information via SMS and phone call, and the center number needs to be set. The default detection time is 3S, and the range can be set from 1-30s. The default driving threshold for sharp turns is 20km/h, and the range can be set from 10-100km/h. The turning angle can be set from 15° to 90°.

Q: Collision alarm
When the vehicle collides with other objects or vehicles during driving, the device can report collision alarm information via SMS and phone calls. The center number needs to be set. The default collision trigger value is 96. The lower the value, the easier it is to trigger. The setting range is 1-255.
