The available scientific evidence does not show that any health problems are associated with using low
power wireless devices. There is no proof, however, that these low power wireless devices are absolutely
safe. Low power wireless devices emit low levels of radio frequency energy (RF) in the microwave range
while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure to
low-level RF that does not produce heating effects causes no known adverse health effects. Many
studies of low-level RF exposures have not found any biological effects. Some studies have suggested
that some biological effects might occur, but such findings have not been confirmed by additional
research.
To satisfy RF exposure requirements, this device and its antenna(s) must operate with a separation
distance of at least 20 centimeters from all persons and must not be co-located or operated in conjunction
with any other antenna or transmitter. End-users must be provided with specific operating instructions for
satisfying RF exposure.
FCC WARNING:
Changes or modifications not expressly approved by the party responsible for compliance could void the
user’s authority to operate the equipment.
The term “IC” before the radio certification number only signifies that Industry Canada technical
specifications were met. Operation is subject to the following two conditions: (1) this device may not
cause interference, and (2) this device must accept any interference, including interference that may
cause undesired operation of the device.
This Class B digital apparatus meets all requirements of the Canadian Interference-Causing Regulations.
I. The device for the band 5150-5250MHz is for indoor usage to reduce potential for harmful
interference to co-channel Mobile Satellite systems.
II. The maximum antenna gain permitted (for devices in the bands 5250-5350 MHz and 5470-
5725 MHz) to comply with the e.i.r.p. limit
III. The maximum antenna gain permitted (for devices in the band 5725-5825 MHz) to
comply with the e.i.r.p. limits specified for point-to-point and non point-to-point operation as
appropriate, as stated in section A9.2(3).
Users should be cautioned to take note that high-power radars are allocated as primary users (meaning
they have priority) of the bands 5250-5350 MHz and 5650-5850 MHz and these radars could cause
interference and/or damage to LE-LAN devices.
To prevent radio interference to the licensed service, this device is intended to be operated indoors and
away from windows to provide maximum shielding. Equipment that is installed outdoors is subject to
licensing.
This device has been designed to operate with the antennas listed below, and having a maximum gain of
3.2dB @ 2.4 GHz and 4.2 dB @ 5 GHz. Antennas not included in this list or having a higher gain are
strictly prohibited for use with this device. The required antenna impedance is 50 ohms.
• Ethertronics Prestta WLAN Embedded Antenna, Part No. 1000418
• Pulse Engineering Dualband WLAN Ceramic Chip Antenna, Part No. W3006
To reduce potential radio interference to others, the antenna type and its gain should be so chosen that
the equivalent isotropically radiated power (EIRP) is not more than required for successful
communication.
The available scientific evidence does not show that any health problems are associated with using low
power wireless devices. There is no proof, however, that these low power wireless devices are absolutely
