11.3 Bit error rate too high

 There is co-frequency signal interference nearby, stay away from the interference source or modify the
frequency and channel to avoid interference；

If the power supply is not ideal, it may also cause garbled characters. Be sure to ensure the reliability
of the power supply.；

Poor quality or too long extension cables and feeders will also cause high bit error rates.
