Kyocera 1135 - Manual (Page 6)

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 1.6W/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 to 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 (e.g., at the ear and worn on the body) as required
by the FCC for each model. The highest SAR value for this model phone when
tested for use at the ear is 1.40 W/kg and when worn on the body, as
described in this user guide, is 0.657 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
