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 of 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. This equipment
has been tested and found to comply
with FCC/ISED radiation exposure
limits set forth for an uncontrolled
environment and meets the FCC radio
frequency (RF) Exposure Guidelines
and RSS-102 of the ISED radio
frequency (RF) Exposure rules.

Compliance with FCC requirement
15.407(c)
Data transmission is always initiated
by software, which is the passed
down through the MAC, through the
digital and analog baseband, and
finally to the RF chip. Several special
packets are initiated by the MAC.
These are the only ways the digital
baseband portion will turn on the RF
transmitter, which it then turns off
at the end of the packet. Therefore,
the transmitter will be on only while
one of the aforementioned packets
is being transmitted. In other words,
this device automatically discontinue
transmission in case of either
absence of information to transmit or
operational failure.
Frequency Tolerance: ±20 ppm
For Customers in Canada
5150-5350 MHz band is restricted
to indoor operation only.
High-power radars are allocated
as primary users (i.e. priority users)
of the bands 5250-5350MHz and
5650-5850MHz and that these
radars could cause interference and/
or damage to LE-LAN devices.
