THIS SIEMENS S46 PHONE 
MEETS THE GOVERNMENT’S RE-
QUIREMENTS FOR EXPOSURE 
TO RADIO WAVES
.
Your wireless Siemens S46 phone is 
a radio transmitter and receiver. It 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. These limits 
are part of comprehensive 
guidelines and establish permitted 
levels of RF energy for the general 
population. The guidelines are based 
on standards that were developed 
by independent scientific 
organizations through periodic and 
thorough evaluation of scientific 
studies. The standards include a 
substantial safety margin designed 
to assure the safety of all persons, 
regardless of age and health.
The exposure standard for wireless 
mobile phones employs a unit of 
measurement known as the Specific 
Absorption Rate, or SAR. The SAR 
limit set by the FCC is 1.6 W/kg.* 
Tests for SAR are conducted using 
standard operating positions 
specified by the FCC with the phone 
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 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.
Before a phone model is available 
for sale to the public, it must be 
tested and certified by the FCC that 
it does not exceed the limit 
established by the government-
adopted requirement for safe 
exposure. The tests are performed 
in positions and locations (for 
example, at the ear and worn on 
the body) as required by the FCC 
for each model. The highest SAR 
value for this Siemens S46 phone 
when tested for use at the ear is 
1.12 W/kg, and when worn on the 
body, as described in this user 
guide, is 0.41 W/kg. (Body-worn 
measurements differ among phone 
models, depending upon available 
accessories and FCC requirements.) 
While there may be differences 
between the SAR levels of various 
phones and at various positions, 
they all meet the government 
requirement for safe exposure.
