Avoid the phone being squeezed between furniture and your

body when carrying the phone in your pocket or attached to

clothing.

Exposure to Radio Frequency Signals (SA)

A cordless telephone is a radio transmitter and receiver. It is

designed and manufactured not to exceed the emission limit for

exposure to radio frequency (RF) energy set by the Federal

Communications Commission of the US government and Canada.

These limits are part of comprehensive guidelines and established

permitted levels of RF energy for the general population. These

guidelines are based on the safety standards previously set by both

US and international standard bodies. These standards include a

substantial safety margin designed to assure the safety of all

persons, regardless of age and health.
The exposure standards for cordless telephones employs a unit of

measure known as the Specific Absorption Rate, or SAR. The SAR

limit set by the FCC and Canada is 1.6W/kg averaged over one

gram of tissue.
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. Before a phone model is available

for sale to the public, it must be tested and certified to the FCC that

it does not exceed the limit established by 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.
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.
For body worn operation, to maintain compliance with FCC RF

exposure guidelines, use only approved accessories. When

carrying the telephone while it is on, use only the specific belt clip

that has been tested for compliance.
Use of non-approved accessories may violate the FCC RF

exposure guidelines and should be avoided.
