If there are multiple sets of products in the same environment, crosstalk can occur (same frequency with the same id code)
Caused by the following steps, the pairing operation can be completely resolved.
1. Set transmission and reception to off state at the same time;
2. Transmitter: Press power button and frequency jump button simultaneously for about 4 seconds, the display will flash quickly.
Status;
