If there are multiple sets of products in the same environment, crosstalk may occur (same frequency with the same ID code)
Caused by the following steps, the pairing operation can be completely solved.
1. Adjust the transmission and reception to the shutdown state at the same time;
2. Transmitter: Press the power switch and the frequency hopping button simultaneously for about 4 seconds, the display will flash quickly.
3. Receiver: Turn on the receiver power, the RF indicator flashes 4 times;
4. Transmitter: Short press the frequency hopping button to exit pairing.
