Sar Certification - SoftBank 931SC User Manual

SAR Certification

931SC meets the technical standards of Ministry
of Internal Affairs and Communications (MIC)
regarding radio wave absorption by a human
body.
These technical standards are established on a scientific basis to prevent radio
waves emitted from wireless devices such as mobile phones that are used close
to human head from affecting human health. These standards assure that the
SAR (Specific Absorption Rate), an indicator of the amount of average energy
absorbed in the side of a human head, must not exceed the permissive value of
2 W/kg*. This value includes a substantial safety margin designated to assure
the safety of all persons, regardless of age and physical size. The value is equal
to the international guideline recommended by International Commission on
Non-Ionizing Radiation Protection (ICNIRP) that has a cooperative relationship
with the World Health Organization (WHO).
The highest SAR value for 931SC is 0.784 W/kg. This value is obtained in
accordance with the MIC testing procedure with the mobile phone transmitting
at its highest permitted power level. While there may be differences in the SAR
levels depending on phones, they all meet the MIC's permissible value. Because
mobile phones are designed to employ the minimum power level required for
the communication with the base station, the SAR of the phone during a call is
usually below the maximum value.

* The guideline is defined by relevant laws and regulations
associated with the Radio Law (No. 2 of Article 14 of
Ordinance Regulating Radio Equipment).
SoftBank's Body SAR Policy
* Body SAR: The SAR value at the maximum transmission power when
continuously talking with handset placed on the body and using earphone-
microphone.
** Specific Absorption Rate (SAR): The value measured when having talked
continuously for 6 minutes.
*** Placement on the body: Measurements are taken with the rear of handset
facing the body at a distance of 1.5 cm as the ordinary handset position. In
order to comply with radio frequency exposure requirements, use an accessory
(e.g. belt clip, holster) that does not contain metallic parts to maintain a 1.5
cm separation between the body and handset.
