3.9 Installation instructions
Generally, the noise can influence the reading functionality of the reader, so it is
recommended to check the place of installation if there could be some source of noise.
The reader uses passive RFID technology on 13,56 MHz frequencies, which could be
sensitive to RF noise sources, either radiated noise or conducted noise to the cable. This
noise could be generated by other equipment, which can generate strong electromagnetic
field or by noisy power supply, which inject noise to the cable. If there are any doubts, it is
recommended to perform a practical test before final mounting.
