How to install the magnet and launcher

The best installation position of the magnet is on the top of the bicycle spoke. The top of the bicycle spoke has a non-circular structure. After the magnet is locked, it will not swing back and forth, and the wireless signal is stable.

The distance between the magnet and the sensor should be kept at about 6mm. If it is too close, it may become unstable.
The magnet corresponds to the center position of the transmitter liked the picture showed, and the signal is more stable and accurate.
Wireless launcher needs a 2032 button cell.

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.
