L L imitations in the USA and Canada
Note
L L imitation of the radiated power (FCC)
RF600 systems that are put into operation in the USA and Canada must not exceed the
following radiated power with an RF620A antenna:
4000 mW EIRP (or 36 dBm EIRP)
Make the following settings to ensure that the maximum permitted radiated power of the
antenna is not exceeded:
Conducted power P (dBm) of the RF600 reader: < 30 dBm
