Please check the stability of the power supply. The voltage cannot fluctuate greatly and frequently ;
Please ensure anti-static operation during installation and use, as high-frequency devices are sensitive to static electricity ;
Please ensure that the humidity during installation and use should not be too high, as some components are humidity-sensitive
devices ;
If there are no special needs, it is not recommended to use it at too high or too low temperature.
12.3 BER(Bit Error Rate) is high
If there is co-channel signal interference nearby, stay away from the interference source or modify the frequency or channel to
avoid interference;
Unsatisfactory power supply may also cause garbled code, so be sure to ensure the reliability of the power supply;
Poor quality or too long extension cords and feeders can also cause a high bit error rate.
