Transceiver  during  the  wa rranty  period,  if  the  quality  of  the  product  itself  rather  than  man -made  da mage   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  fla mmab le p laces such as coal mines or near e xplosive at mospheres 

(such as detonators). 

4.

 

Please use the appropriate DC powe r supply, high  frequency interference ab ility, s ma ll ripple, and enough load 

capacity are required; it’s better to have over current, over vo ltage protection and lightning protection and othe r functions 

to ensure that transceiver working  properly. 

5.

 

Please do not use it  in the  working environment beyond the transceiver environ mental characteristics , such as 

high temperature, humidity,  low  temperature, strong electromagnetic fields or dust large r 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.

 

Wire less  data  transceiver  has  different  communication  distance  in  different  environ ments  ,  communication  

distance is influenced by temperature, humid ity, obstacle density, obstacle volume and electro magnetic  environment; in  

order to ensure stable communication,  it is recommended  to reserve at least 50 % of the communication  distance.  

10.

 

When  communication  d istance  is  not  perfect,  it  is  reco mmended  to  imp rove  the  antenna  quality  and  the 

installation mode of the antenna. You can send mail  to [email protected] for support. 

11.

 

When choosing power supply, it is reco mmended to keep at least 50% current le ft and the ripple must not e xceed 

100mV. 

12.Important statement

 

1. CDEBYTE  reserves the right of final  interpretation  and modification  of all  the contents of this manual. 

2. As the hardware and software products continuously improving, this manual may subject to change without notice, 

please refer to the latest version. 

3.  Everyone is responsible for protecting the environ ment: to  reduce the use of paper, we  only prov ide electronic  

documents of  the  English  manual,  if  necessary,  please  go to our  officia l  website  to  download;  In  addition,  for  special 

require ments, we agree to offer certa in a mount of documents according to o rder quantity, not every data transceiver are 

supplied with one manual,  please understand;
