Specific Absorption Rate of Mobile
Phone
This model ISW13F 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
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 0.475 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. Therefore 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 present

and limits
scientific information does not indicate the use of mobile
devices has nay harmful effects on the human body. They
recommend that if you are still worried about your exposure
then you can limit your talk time or use a handsfree kit to
keep the mobile phone away from your head and body. If you
would like to know more detailed information, please refer to
the WHO website.
