For Customers in the U.S.A.
and Canada
This equipment complies with FCC
radiation exposure limits set forth for an
uncontrolled environment and meets
the FCC radio frequency (RF) Exposure
Guidelines. This equipment has very
low levels of RF energy that is deemed
to comply without testing of specific
absorption rate (SAR).
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 ISED radiation
exposure limits set forth for an
uncontrolled environment and meets
RSS-102 of the ISED radio frequency (RF)
Exposure rules.

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.
Important note on use of 5 GHz wireless
LAN
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.
