Specific Absorption Rate Data - Motorola V70 User Manual

Specific Absorption Rate Data

This model phone meets the government's requirements for
exposure to radio waves.
Your mobile phone is a radio transmitter and receiver. It is designed and
manufactured not to exceed limits for exposure to radio frequency (RF) energy.
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 organisations through periodic and
thorough evaluation of scientific studies. The guidelines include a substantial
safety margin designed to assure the safety of all persons, regardless of age and
health.
The exposure standard for mobile phones employs a unit of measurement known
as the Specific Absorption Rate, or SAR. Under the guidelines for your phone
∗
model, the SAR limit is 2.0 W/kg . Tests for SAR are conducted using standard
operating positions 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 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 base station, the lower the power output of the
phone.
Before a phone model is available for sale to the public, it is tested to confirm
compliance with the guidelines. The tests are performed in positions and locations
(e.g., at the ear and worn on the body) that conform to a uniform testing
methodology determined by an expert standards body. The highest SAR value for
this model phone when tested for use at the ear is 0.97 W/kg and when worn on
the body, as described in this user guide, is 0.52 W/kg. (Body-worn
measurements differ among phone models, depending upon available accessories
and regulatory requirements).
While there may be differences between the SAR levels of various phones and at
various positions, they all meet the governmental requirements for safe exposure.
∗
The SAR limit for mobile phones used by the public is 2.0 watts/kilogram (W/kg)
averaged over ten grams of tissue. The limit incorporates a substantial margin for
safety to give additional protection for the public and to account for any
variations in measurements.
