Safety Precautions
923SH meets the government's requirements
for exposure to radio waves.
These requirements are based on scientific basis to
assure that radio waves emitted from mobile phones
and other handheld wireless devices do not affect
human health. They require that the Specific
Absorption Rate (SAR), which is the unit of
measurement for the amount of radiofrequency
absorbed by the body, shall not exceed 2 W/k
g
*
. This
limit includes a substantial safety margin designed to
assure the safety of all persons, regardless of age or
health, and meets the international standard set by
International Commission on Non-Ionizing Radiation
Protection (ICNIRP) in cooperation with World
Health Organization (WHO).
All mobile phones, prior to product launch, must be
certified as compliant with government requirements
as stipulated by the Radio Law. 923SH has been
granted Technical Regulations Conformity
Certification by TELECOM ENGINEERING
CENTER. Its highest SAR value is 0.493 W/k
g
. This
value was obtained by TELECOM ENGINEERING
CENTER as part of the certification process. SAR
tests were conducted with handset transmitting at its
highest certified power level in accordance with
testing methods set by the government. While there
may be differences between the SAR levels for
various handsets, they all meet the governmental
requirements for safe exposure. The actual SAR
level of the handset while operating can be well
below the highest value. This is because the
handset is designed to operate at multiple power
levels so as to use only the power required to reach
the Network.
Additional information on SAR can be obtained on
the following Websites.
