Information on Specific Absorption Rate (SAR)
This device meets the limits for protecting the health of the public from the effecs of
exposure to electromagnetic fields when it is operated in connection with the desig-
nated antenna(s) like described in the user manual.
Your device is a radio transmitter and receiver. It is designed and manufactured not to
exceed the limits for exposure to emission from electromagnetic fields recommended
by international guidelines from the International Commission on Non-Ionizing Radia-
tion Protection (ICNIRP). These limits are part of comprehensive guidelines for the pro-
tection of the public and establish permitted levels of exposure to electromagnetic radi-
ation for the population. The guidelines were confirmed by independent scientific
organisations through periodic and thorough evaluation of scientific studies. The limits
include a substantial safety margin designed to assure the safety of all persons, regard-
less of age and health.
The exposure limit employs a unit of measurement known as the Specific Absorption
Rate, or SAR. The SAR limit stated in the international guidelines is 2.0 W/kg. Tests for
SAR are conducted in all frequency bands with the device transmitting at its highest
power level with minimum possible distance to the body. The actual SAR level of the
device during operation with the designated antenna(s) is below the maximum value
and is additionally decreased by a distance to the device. This is because the device is
designed to operate at multiple power levels so as to use only the power required to
enable seamless network connection.
Information about the optional outdoor antenna
Wall duct:
To connect the SE681 WiMAX to the outdoor antenna, the antenna cable must be fed
through the wall to the outside of the building. It must be possible to make a suitable
wall or window duct at or near the location of the SE681 WiMAX.
Only one of the antennas listed on page 12 must be used.
The outdoor antenna must be installed and put into service by a qualified
electrician.
Only commence the outdoor work once you have taken all the nec-
essary steps to make the location safe.
Be sure to observe the safety instructions.
