Sar Certification Information - SoftBank 840N User Manual

Before Using This Guide
Caution
Do not use handset if it has been altered. Using an
altered device is a violation of the Radio Law.
This handset is certified to conform to the
technical standards for specific radio equipment
based on the Radio Law, and Technical
Conformity Mark is printed on the model
name seal as certification. If you remove screws
and make alterations inside of handset, the
technical standards conformity certification
becomes invalid. Do not use handset with the
certification invalid, as it is a violation of the Radio
Law.

SAR Certification Information

840N meets the technical standards set by the
Ministry of Internal Affairs and Communications
(MIC) regarding radio wave absorption by a
human body.
These technical standards have been established
on a scientific basis to prevent radio waves
emitted from wireless devices such as mobile
phones from affecting human health. These
standards require that the SAR (Specific
Absorption Rate), an indicator of the amount of
average radio frequency energy absorbed in the
side of a human head, must not exceed 2 W/kg*.
This value includes a substantial safety margin to
assure the safety of all persons, regardless of age
and physical size. The value is equal to the
international guideline recommended by the
International Commission on Non-Ionizing
Radiation Protection (ICNIRP) that has a
xvi
cooperative relationship with the World Health
Organization (WHO).
* The technical standards are stipulated in the
Radio Law (Article 14-2 of Ordinance
Regulating Radio Equipment).
The highest SAR value is 0.552 W/kg for 840N.
This value was obtained in accordance with the
MIC testing procedure with handset transmitting
at its highest permitted power level. While there
may be differences in SAR levels for various
handsets, they all meet the MIC ' s permissible
value. Because mobile phones are designed to
operate at their minimum power level required to
communicate with base stations, the actual SAR
of handset during a call is usually below the
highest value.

SoftBank's Body SAR Policy
Body SAR: Value obtained from continuously
･
talking with handset placed on the body using
earphone-microphone at maximum
transmission power.
Specific Absorption Rate (SAR): Value obtained
･
from talking continuously for six 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 standard 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.

European RF Exposure Information
840N is a radio transmitter and receiver. This
product has been confirmed not to exceed the
limits recommended by international guidelines
for radio frequency.
These guidelines were developed by the
independent scientific organization International
Commission on Non-Ionizing Radiation
Protection (ICNIRP) and include a substantial
safety margin to assure the safety of all persons,
regardless of age and health.
The influence on the human body of radio waves
emitted from mobile phones is measured
employing a unit known as the Specific
Absorption Rate (SAR). The SAR limit for mobile
devices is 2 W/kg. The maximum SAR value for
this model handset, when placed on the ear, is
0.544W/kg. As mobile devices offer a range of
functions, they can be used in other positions,
such as on the body as described in SoftBank ' s
