Guidelines for Safe and Efficient Use
3
margin designed to assure the safety of all persons,
regardless of age and health, and to account for any
variations in measurements.
Specific Absorption Rate (SAR) is the unit of measurement
for the amount of radio frequency energy absorbed by
the body when using a mobile phone. The SAR value is
determined at the highest certified power level in laboratory
conditions, but the actual SAR level of the phone while
operating can be well below this value.
This is because the phone is designed to use the minimum
power required to reach the network. Therefore, the closer
you are to a base station, the more likely it is that the actual
SAR level will decrease.
Variations in SAR below the radio frequency exposure
guidelines do not mean that there are variations in safety.
While there may be differences in SAR levels among
mobile phone models, all mobile phone models must be
designed to meet radio frequency exposure guidelines.
Accessories can significantly affect SAR compliance. For
example, the Federal Communication Commission in
the U.S. requires that some manufacturers’ accessories
shall be tested, and Sony Ericsson has done so with
respect to its products. Sony Ericsson has not tested
non-original accessories in conjunction with Ericsson
mobile phones. It is therefore recommended that only
original accessories are used in conjunction with Ericsson
mobile phones.
