Specific Absorption Rate (SAR) of Cell
Phones
This model 【SHV40】 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/kg. The highest SAR value for this cell phone when
tested for use near the head is 0.409 W/kg (*2), and when worn on the body,
is 0.397 W/kg (*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 operating 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 head. 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”.
