3. In some flammable places (such as coal mines) or explosive dangerous objects (such as detonators) nearby, do not
operate this radio.
4. Use a suitable DC regulated power supply with strong anti-high frequency interference, small ripple, and sufficient
carrying capacity; preferably with over-current, over-voltage protection and lightning protection to ensure the normal
operation of the digital radio.
5. Do not use the digital radio in an environment that exceeds its environmental characteristics, such as high temperature,
humidity, low temperature, strong electromagnetic field or dusty environment.
6. Do not keep the digital radio in a continuous full-load transmitting state, otherwise the transmitter may be burned out.
7. The ground of the digital radio should be well connected with the ground of external devices (such as PC, PLC, etc.)
and the ground of the power supply, otherwise the communication interface will be burned easily; do not plug or unplug
the serial port with electricity.
8. When testing the digital radio, you must connect a matching antenna or 50 ohm dummy load, otherwise it will easily
damage the transmitter; if the antenna is connected, the human body should be more than 2 meters away from the
antenna to avoid damage, and do not touch the antenna while transmitting.
9. Wireless digital radio often has different communication distances in different environments, and the communication
distance is often affected by temperature, humidity, obstacle density, obstacle volume, and electromagnetic environment;
in order to ensure stable communication, it is recommended to set aside more than 50% of the communication distance
margin.
10. If the measured communication distance is not satisfactory, it is recommended to improve the communication
distance by analyzing the antenna quality and the antenna installation method. Contact with us [email protected], for
help.
11. When choosing the power supply, in addition to the recommended 50% current margin, it should be noted that the
ripple should not exceed 100mV.
