SAR Certification
730SC 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 2W/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 730SC is 0.737 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.
