regulation, all WiFi product marketed in US must fixed to US operation channels only.
RF Exposure Information (SAR)
This device meets the government’s requirements for exposure to radio waves.
This device is designed and manufactured not to exceed the emission limits for exposure to radio frequency
(RF) energy set by the Federal Communications Commission of the U.S. Government.
16
The exposure standard for wireless device employs a unit of measurement known as the Specific Absorption
Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg. *Tests for SAR are conducted using standard operating
positions accepted by the FCC with the device transmitting at its highest certified power level in all tested
frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level
of the device while operating can be well below the maximum value. This is because the device is designed
to operate at multiple power levels so as to use only the poser required to reach the network. In general,
the closer you are to a wireless base station antenna, the lower the power output.
While there may be differences between the SAR levels of various devices and at various positions, they all
meet the government requirement.
For body worn operation, this device has been tested and meets the FCC RF exposure guidelines for use
with an accessory that contains no metal and be positioned a minimum of 1.0cm from the body. Use of
other accessories may not ensure compliance with FCC RF exposure guidelines. If you do not use a
body-worn accessory and are not holding the device at the ear, position the handset a minimum of 1.0cm
from your body when the device is switched on.
