1. Please keep the warranty card of the equipment which includes the factory number (and important technical
parameters) and is important for user's future maintenance and new equipment .
2. Transceiver during the warranty period, if the quality of the product itself rather than man-made damage or
lightning and other natural disasters caused by damage, enjoys free warranty; please do not repair by yourself, the
problem and please contact with our company when problem occurring , we offer the first-class after-sales service.
3. Please do not operate the transceiver in some flammable places such as coal mines or near explosive atmospheres
4. Please use the appropriate DC power supply, high frequency interference ability, small ripple, and enough load
capacity are required; it’s better to have over current, over voltage protection and lightning protection and other functions
to ensure that transceiver working properly.
5. Please do not use it in the working environment beyond the transceiver environmental characteristics , such as
high temperature, humidity, low temperature, strong electromagnetic fields or dust larger environment.
6. Please do not continuously keep transceiver to transmit in full capacity, or the transmitter might be damaged.
7. Please connect the ground with the external ground of the power supply (such as PC, PLC, etc.) , otherwise it is
easy to burn out the communication interface; do not plug the interface with power supplying.
8. When testing, please connect the antenna or 50 Ω load, otherwise transceiver will be damaged easily ;the
distance from the antenna is better than 2 meters, so as to avoid harm, please do not touch the antenna when
transmitting.
9. Wireless data transceiver has different communication distance in different environments , communication
distance is influenced by temperature, humidity, obstacle density, obstacle volume and electromagnetic environment; in
order to ensure stable communication, it is recommended to reserve at least 50 % of the communication distance.
10. When communication distance is not perfect, it is recommended to improve the antenna quality and the
installation mode of the antenna. You can send mail to support@cdebyte.com for support.
11. When choosing power supply, it is recommended to keep at least 50% current left and the ripple must not exceed
