This model Galaxy A20 mobile phone complies with
Japanese technical regulations and international
guidelines regarding exposure to radio waves.
The product 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 model handset when tested for
use at the ear is 0.531 W/kg
(*2)
and when worn
on the body is 0.200 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 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.
