12.2 Module vulnerable to damage
please check the power supply to ensure that it is between the recommended supply voltages, as exceeding the
maximum will cause permanent damage to the module.
please check the stability of the power supply, the voltage should not fluctuate significantly and frequently.
please ensure that the installation and use process is anti-static operation, high frequency devices electrostatic
sensitivity.
please ensure that the humidity during installation and use should not be too high, some components are
humidity sensitive devices.
if there is no special demand is not recommended to use in too high or too low temperature.
12.3 Too high BER
There is interference from co-channel signals near
, stay away from sources of interference or modify the
frequency or channel to avoid interference.
Poor power supply to
may also cause garbled codes, be sure to ensure the reliability of the power supply.
poor quality or too long extension cables and feeders can also cause high BER.
