Appendix
Specific Absorption Rate (SAR) of
Cell Phones
This model
【
SHF32
】
cell phone complies with Japanese technical
regulations for exposure to radio waves and international guidelines
on radio wave protection.
This cell 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 body. The SAR limit
for cell phones is 2.0 W/k
g
. The highest SAR value for this cell phone
when tested for use at the ear is 0.410 W/k
g
, and when worn on the
body, is 0.439 W/k
g
(*2)
. There may be slight differences in SAR levels
among individual products, but they all satisfy the limit.
The actual SAR of this cell phone while talking on the phone can be
well below that indicated above. This is due to the cell phone being
designed to only output 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 cell phone.
This cell phone can be used in positions other than against your ear.
Use a carrying case or similar accessory that holds the phone at least
1.5 cm separated from the body and ensure no metal parts are
located between you and the cell phone. Under these conditions, this
cell phone satisfies Japanese technical regulations and international
guidelines for radio wave protection.
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”.
