5.2 Module is easy to damage 

 

Please check the power supply and ensure it is within  the recommended  range. Voltage  higher than the peak will  lead 
to a permanent damage to the module. 

 

Please check the stability of power supply and ensure the voltage not to fluctuate too much. 

 

Please make  sure anti-static measures are taken when installing and using, high frequency devices have electrostatic 
susceptibility.   

 

Please ensure the humidity  is within limited  range for some parts are sensitive to humidity.   

 

Please avoid using modules under too high or too low temperature. 

5.3 High bit error rate 

 

There are co-channel signal interference nearby, keep away from  interference sources or modify  frequency, channel 
to avoid interference. 

 

Unsatisfactory power supply may also cause garbled characters, and ensure the reliability  of the power supply. 

 

If the extension cable or feeder is of poor quality or too long, the bit error rate will  be high.
