Antenna Requirements
The antennas used with this transmitter must be professionally installed in a
manner which guarantees compliance with all local laws and regulations.
Note 1: To comply with EN 302 208, the installer must use an antenna whose beamwidth shall be
less than or equal to 90 degrees for transmit ERP levels less than or equal to 500 mW. For
transmissions above 500mW and less than or equal to 2W, a minimum antenna beamwidth
of 70 degrees is required.
Note 2: In accordance with local regulation.
FCC Radiation Exposure Statement
The antennas used for this transmitter must be installed to provide a separation distance
of at least 20 cm from all persons and must not be co-located or operating in conjunction
with any other antenna or transmitter.
Caution
To prevent reader damage, the RF port must be properly terminated with a 50 Ohm load
or a functional UHF RFID antenna before power up. Never power up the reader unless the
loads or antennas are connected. Always power down the reader before removing an
antenna or load from an RF port.
Environmental Specifications
Caution
The actual internal module temperature is a function of the operating conditions and end
product enclosure environment. The maximum recommended module internal operating
temperature is +85°C and can be monitored with host software. The embedded RFID
application should be verified and monitored for compliance.
