Caution:
For Model ID4100-001
This device is designed to operate with a 9.5 dBiC (9.0 dBiC for ETSI) gain internal and
external antenna and conducted power is factory set to 23 dBm (200 mW). When conducted
power is set to 29 dBm (0.871 W), the antenna gain cannot exceed 9.5 dBiC. Antenna
having a higher gain is strictly prohibited per FCC and Industry Canada regulations when
utilizing maximum power. Power into the antenna must decreased to compensate for any
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.
