Professional Installation Guidelines for the U.S.
4 Professional Installation Guidelines for the U.S.
4.1 Installation Personnel
UHF RFID readers require professional installation!
ŹYou must be a professional installer with RF and related rule knowledge.
ŹThe installation requires special trained professionals to access and setup the system.
ŹThe system is not to be installed by the general public, general user shall not attempt to install
the device or change the settings.
4.2 External Antenna
ŹYou must follow Part 15 of the FCC rules, and specifically Part 15.203 pertaining antenna require-
ments of an intentional radiator.
ŹMake sure to use a 13dBi or less patch antenna.
ŹOnly use antennas which have been approved by the applicant. The use of none-approved anten-
na(s) may produce unwanted spurious emissions or excessive RF transmitting power which may
lead to the violation of the FCC/ISED limit and is prohibited.
4.3 Final Output Power
WARNING
ŹCarefully select the installation position.
ŹMake sure that the final output power does not exceed the limit set in relevant rules. The viola-
tion of the rule could lead to serious federal penalty!
If you are not a professional installer, STOP.
ŹDo not proceed any further with the installation.
ŹDo not install the unit or change the settings.

Safety Instructions
NOTICE
Risk of malfunction!
ŹMake sure the reader is properly grounded according to the corresponding national standards.
ŹMake sure that the diameter of the ground cable is min. 6 mm2 (typ. 10 mm2).
ŹMake sure to ground the reader such that the distance between the reader ground point and the
ground point in the building is as short as possible.
ŹNote that the equipotential bonding does not replace lighting protection.
5.2
CE Marking for the Kathrein RFID Readers with the Type Designation ETSI
WARNING
Danger to life due to radiation electromagnetic field!
This reader is designed ETSI
for operation according to EN302208. In some circumstances, heart
pacemakers may suer interference if wearers are close to the antenna when the unit is in operation
(reader and antenna).
ŹWhen the unit is operated with antennas connected, comply with the human exposure regulations
in accordance with EN 50364.
ŹEnsure a minimum clearance of 35cm between the antenna and the human body.
ŹComply with the operating instructions for RFID antennas.
ŹIn case of doubt, make sure people with peacemakers contact the manufacturer of their peace-
maker or their doctor.
5.3
FCC and ISED Canada Regulatory Information
The operator and the specialist company which carries out the installation are responsible for ensuring that
only certified systems are used in the United States. Use of this system in any other combination (e.g. sev-
eral antennas which transmit the same information in the same location) is expressly prohibited. Changes
