The exposure standard for phones employs a unit of measurement known as the Specific Absorption Rate,
or SAR. The SAR limit set by public authorities such as the Federal Communications Commission of the
US Government (FCC), or by Innovation, Science and Economic Development Canada (ISEDC), is 1.6 W/kg
averaged over 1 gram of body tissue. Tests for SAR are conducted using standard operating positions with
the phone transmitting at its highest certified power level in all tested frequency bands.
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: 2ACCJN039.
Although the SAR is determined at the highest certified power level, the actual SAR level of the phone
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 of the phone. Before a phone model
is available for sale to the public, compliance with national regulations and standards must be shown.
The highest SAR value for T790W when tested is 1.34 W/Kg for use at the ear and 1.12 W/Kg for use close
to the body.
While there may be differences between the SAR levels of various phones and at various positions, they all
meet the government requirement for RF exposure.
For body-worn operation, the phone meets FCC RF exposure guidelines provided that it is used with a non-
metallic accessory with the handset at least 15 mm from the body.
Use of other accessories may not ensure compliance with FCC RF exposure guidelines.
