Important Tips

For possible reading inaccuracies, customers should know the following information
1. the distance between monitor and sensor should below 80 cm
2. the distance between sensor and magnetic should below 3 mm
3. In order to enhance anti-interference, we used ID coding technology in the design. When the battery is just installed, the speed sensor needs to work continuously for 1 minute to recognize the new sensor.Please refer to the video and test for one minute, then check if the speed sensor is working properly
4. The wrong installation of the speed sensor will also cause 0 display. please refer to the picture below to make sure the installation is right.
By the way, this bicycle computer is a wireless product, and the electromagnetic waves of the environment will affect its normal operation.
When using it, we should avoid the electrical equipment at work: household appliances, high-voltage wires, transformers, high-voltage cables, charging stations, elevators and other electrical equipment at work (code table speed display 0 when interfered by them)
5.The Data Sensor consists of a receiver and a magnet. To accurately measure the data, the sensor must be fixed firmly. The receiver should be aligned with the magnet at the same level.
