RF Exposure Information (SAR)
This phone 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 United
States.
25
During SAR testing, this device was set to transmit at its highest
certified power level in all tested frequency bands, and placed in
positions that simulate RF exposure in usage against the head
with no separation, and near the body with the separation of 10
mm. 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
phone is designed to operate at multiple power levels so as to
use only the power required to reach the network. In general, the
closer you are to a wireless base station antenna, the lower the
power output.
The exposure standard for wireless devices employing a unit of
measurement is known as the Specific Absorption Rate, or SAR.
The SAR limit set by the FCC is 1.6W/kg.
This device is complied with SAR for general population
/uncontrolled exposure limits in ANSI/IEEE C95.1-1992 and had
been tested in accordance with the measurement methods and
procedures specified in IEEE1528.
The FCC has granted an Equipment Authorization for this model
phone with all reported SAR levels evaluated as in compliance
with the FCC RF exposure guidelines. SAR information on this
model phone is on file with the FCC and can be found under the
Display Grant section of www.fcc.gov/oet/ea/fccid after searching
on FCC ID: . N2GDP355
For this device, the highest reported SAR value for usage against
the head, body-worn accessory, and product specific (Hotspot)
are 1.23 W/kg, 0.83 W/kg, and 0.84 W/kg respectively.
While there may be differences between the SAR levels of
various phones and at various positions, they all meet the
government requirements.
SAR compliance for body-worn operation is based on a
separation distance of 10 mm between the unit and the human
body. Carry this device at least 10 mm away from your body to
ensure RF exposure level compliant or lower to the reported level.
To support body-worn operation, choose the belt clips or
26
holsters, which do not contain metallic components, to maintain a
separation of 10 mm between this device and your body.
RF exposure compliance with any body-worn accessory, which
contains metal, was not tested and certified, and use such
body-worn accessory should be avoided.
