FEDERAL COMMUNICATIONS COMMISSION
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions:(1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
Changes or modifications not expressly approved by the party responsible for
compliance could void the user‘s authority to operate the equipment.
NOTE
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiated radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not
occur in a particular installation If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
Note:
This device and its antenna(s) used for this transmitter must not be co-located or
operating in conjunction with any other antenna or transmitter.
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. In order to avoid the possibility of exceeding the FCC
radio frequency exposure limits, human proximity to the antenna shall not be less than
20cm (8 inches) during normal operation.
According to 15.407(e):
If this device is going to be operated in 5.15 ~ 5.25GHz frequency range, then it is
restricted in indoor environment only.
RSS-GEN-7.1.4 Transmitter Antenna:
To reduce potential radio interference to other users, the antenna type and its gain of 8dBi.
should be so chosen that the equivalent isotropically radiated power (EIRP) is not more
than that required for successful communication.
This device has been designed to operate with an antenna having a maximum gain.
Antenna haveing a higher gain is strictly prohibited per regulations of industry
Canada. 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 (e.i.r.p.) is not more than
that permitted for successful communication.
