Chapter 10 Precautions for Use
1. Please keep the warranty card of this device properly. The warranty card contains the factory number (and important technical
parameters) of the device, which is of great reference value for users to maintain and add new devices in the future.
2. During the warranty period, if the radio station is damaged due to the quality of the product itself rather than man-made damage
or natural disasters such as lightning strikes, it will enjoy free warranty; please do not repair it yourself, and contact our company
if there is a problem. Ebyte provides first-class After sales service.
3. Do not operate this radio near some flammable places (such as coal mines) or explosive dangerous objects (such as detonators for
detonation).
4. A suitable DC stabilized power supply should be selected, which requires strong anti-high-frequency interference, small ripple,
and sufficient load capacity; it is best to have over-current, over-voltage protection and lightning protection functions to ensure
the normal operation of the digital transmission station. Work.
5. Do not use it in a working environment that exceeds the environmental characteristics of the data transmission station, such as
high temperature, humidity, low temperature, strong electromagnetic field or dusty environment.
6. Don't let the digital radio continuously transmit at full capacity, otherwise it may burn out the transmitter.
7. The ground wire of the digital transmission station should be well connected with the ground wire of the external equipment
(such as PC, PLC, etc.) and the ground wire of the power supply, otherwise the communication interface will be easily burned out;
do not plug or unplug the serial port while the power is on.
8. When testing the digital radio station, it must be connected with a matching antenna or a 50Ω dummy load, otherwise the
transmitter will be easily damaged; if the antenna is connected, the distance between the human body and the antenna should
preferably exceed 2 meters to avoid injury Touch the antenna while transmitting.
9. Wireless data transmission stations often have 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 reserve more than 50% communication distance
margin.
10. If the measured communication distance is not ideal, it is recommended to analyze and improve the communication distance from
the quality of the antenna and the installation method of the antenna. You can also contact [email protected] for help .
11. When choosing a power supply, in addition to keeping a 50% current margin as recommended, you should also pay attention to
its ripple not exceeding 100mV.
