Specific Absorption Rate
(SAR) of cell phones
This model VEGA (PTL21) 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 0.464 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
