This device contains an FCC approved RF module.
The transmitter carries FCC ID: R68WIPORTG.
RSS-GEN Sections 7.1.4 and 7.1.5 Statement for Devices with Detachable Antennas
This device has been designed to operate with the antennas listed in the Certificate, and
having a maximum gain of 5 dB. Antennas not included in this list or having a gain greater
than 5 dB are strictly prohibited for use with this device. 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.
Note:
a) This module is authorized under limited module approval specified to mobile host
equipment. So, the antenna must be installed such that 20cm is maintained between the
antenna and users.
b) The transmitter module may not be co-located with any other transmitter or antenna.
