Other Information
 The SAR value is determined at the highest certified
power level in laboratory conditions, but the actual
SAR level of the Reader while it is operating can be
well below this value.
 This is because the Reader is designed to use the
minimum power required to reach the network.
 Variation in SAR below the radio frequency exposure
guidelines do not mean that there are variations in
safety.
 While there may be difference in SAR levels among
Readers, all Sony Reader models are designed to
meet radio frequency exposure guidelines.
 The tests are performed in positions and locations as
required by FCC for each model.
 This Reader model PRS-900 has been designed to
comply with applicable safety requirements for
exposure to radio waves. These requirements are
based on scientific guidelines that include safety
margins designed to assure the safety of all persons,
regardless of age and health.
 The radio wave exposure guidelines employ a unit of
measurement known as the Specific Absorption
Rate, or SAR. Tests for SAR are conducted using
standardized methods with the Reader transmitting
at its highest certified power level in all used
frequency bands.
 SAR data information for residents in countries that
have adopted the SAR limit recommended by the
ICNIRP, which is 2W/kg averaged over 10g of issue.
In other countries, such as the US, the adopted limit
is 1.6 W/kg averaged over 1g of issue.
