NOTICE: This device has been designed to operate with no more than 1 Watt into the antenna and an
antenna gain of no more than 6 dBi, linear. Antenna having a higher gain is strictly prohibited
per FCC and Industry Canada regulations, unless power into the antenna is decreased to
compensate for the increased antenna gain. The required antenna impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and its gain should be
so chosen that the equivalent isotropically radiated power (EIRP) is not more than that
required for successful communication.
The installer of this radio equipment must ensure that the antenna is located or pointed such
that it does not emit an RF field in excess of Health Canada limits for the general population;
consult Safety Code 6, obtainable from Health Canada’s website at:
