Appendix
Specific Absorption Rate (SAR) of
Cell Phones
This model 【SHL22】 mobile phone complies with
Japanese technical regulations and international
guidelines regarding exposure to radio waves. This
mobile phone has been designed in observance of the
Japanese technical regulations regarding exposure to
radio waves (*1) and limits to exposure to radio waves
recommended by equivalent international guidelines.
These international guidelines were set out by the
International Commission on Non-Ionizing Radiation
Protection (ICNIRP), which is in collaboration with the
World Health Organization (WHO), and the permissible
limits include a substantial safety margin designed to
assure the safety of all persons, regardless of age and
health condition. The Japanese technical regulations
and international guidelines define the limits using a
unit of measurement known as the Specific Absorption
Rate (SAR), which represents the average amount of
radio frequency energy absorbed by the human head.
The SAR limit for mobile phones is 2.0 W/kg. The
highest SAR value for this mobile phone when tested
for use at the ear is 0.282 W/kg. There may be slight
differences in SAR levels among individual products,
but they all satisfy the limit. The actual SAR of this
mobile phone while talking on the phone can be well
below that indicated above. This is due to automatic
changes in the power level of the mobile phone to
ensure it only outputs the minimum power required to
communicate with a base station. Therefor
e in general,
the closer you are to a base station, the lower the
power output of the mobile phone.
This mobile phone can be used in positions other than
against your ear. This mobile phone satisfies the
international guidelines when used with au Carrying
Case F Black (0105FCA) (sold separately)
recommended by KDDI (*2).
In case you are not using the au Carrying Case F Black
(0105FCA) (sold separately), use a product that
contains no metal parts, and one that can hold the
mobile phone at least 1.5 cm away from your body.
The World Health Organization has stated that “a large
number of studies have been performed over the last
two decades to assess whether mobile phones pose a
potential health risk. To date, no adverse health effects
have been established as being caused by mobile
phone use”. If you would like to know more detailed
information, please refer to the WHO website.
