9. Important Notes

1. Please do not operate the devices at or near inflammable or explosive areas.
2. Please select stable DC power supply sources, which should have strong anti-interference ability and low ripple as well as load capacity; it is better to
have overcurrent or overvoltage and lightning protection in order to ensure normal operation.
3. Please do not use the devices at environment that exceeds the limitation such as high temperature, high humidity, low temperature, strong
electromagnetic or dusty environment.
4. Please do not make the devices work continuously at overload status, or it will damage the devices.
5. The ground electrode of the transceiver should be connected firmly to the external device's (PC, PLC, ETC.) and power source ground electrode, or
it is easy to damage the communication interfaces; please do not plug on or off the serial port with power on.
6. When testing the transceivers, matched antennas or 50Ω dummy load must be connected, or it is easy to damage the devices; if antenna connected,
human body should be at least 2 meters from the antenna to avoid injury, and do not touch the antenna when it is transmitting.
7. Under different environment, the communication distance will be different. Communication distance will be affected by temperature, humidity,
blockage density, blockage size and electromagnetic environment; in order to have stable communication, at least 50% communication allowance is
recommended to be kept.
8. If the tested communication distance is not ideal, please also consider about improving the antenna quality and antenna installation. Or please
