Radio Wave Exposure and Specific
Absorption Rate (SAR) Information
【305SH】 here refers to this mobile phone 【AQUOS
Specific Absorption Rate (SAR) for This
Product (for Japan)
This mobile phone 【305SH】 meets the Japanese technical
regulations* and international guidelines for exposure to radio
The Japanese technical regulations for exposure to radio
frequency energy established permitted levels of radio
frequency energy, based on standards developed by
independent scientific organizations through periodic and
thorough evaluation of scientific studies.
The regulation employs a unit of measurement known as the
Specific Absorption Rate, or SAR.
The SAR limit is 2 watts/kilogram (W/kg) averaged over ten
grams of tissue.
The limit includes a substantial safety margin designed to
assure the safety of all persons, regardless of age and health.
The value of the limit is equal to the value given in
international guidelines recommended by ICNIRP**, which is in
collaboration with the World Health Organization (WHO).
The highest SAR value for this mobile phone is 0.614 W/kg
when tested for use at the ear, and 0.435 W/kg*** when worn
on the body in the below manner****.
While there may be differences between the SAR levels of
various phones and at various positions, all phones meet the
Japanese technical regulations.
Although the SAR is determined at the highest certified power
level, the actual SAR of the phone during operation can be
well below the maximum value.
Use at positions other than at the ear****
This mobile phone may be used at positions other than at the
ear. By using an accessory such as a belt clip holster that
maintains a 1.5 cm separation with no metal (parts) between
the body and the mobile phone, this mobile phone will comply
with international guidelines for radio wave protection.
* The technical regulation is provided in Article 14-2 of the
Ministry Ordinance Regulating Radio Equipment.
** International Commission on Non-Ionizing Radiation
*** The value is under simultaneous transmission use
The World Health Organization has announced that "A large
number of studies have been performed over the last two
decades to assess whether mobile phones pose a potential
health risk. To date, no adverse health effects have been
established as being caused by mobile phone use."

RF Exposure Information
This mobile phone 【305SH】 is confirmed to comply with
guidelines relating to effects of radio wave exposure as
set forth by the Council of Europe (CE) and the Federal
Communications Commission (FCC).
Refer to the following.
■European RF Exposure Information
Your mobile device is a radio transmitter and receiver. It is
designed not to exceed the limits for exposure to radio waves
recommended by international guidelines. These guidelines
were developed by the independent scientific organization
ICNIRP and include safety margins designed to assure the
protection of all persons, regardless of age and health. The
guidelines use a unit of measurement known as the Specific
Absorption Rate, or SAR. The SAR limit for mobile devices
is 2.0 W/kg and the highest SAR value for this device when
tested at the ear is 0.501 W/kg*.
As mobile devices offer a range of functions, they can be used
in other positions, such as on the body as described in this
User Guide. In this case, the highest tested SAR value is 0.438
* The tests are carried out in accordance with international
guidelines for testing.
■FCC RF Exposure Information
Your handset is a radio transmitter and receiver. It is
designed and manufactured not to exceed the emission limits
for exposure to radio frequency (RF) energy set by the Federal
Communications Commission of the U.S. Government.
The guidelines are based on standards that were developed
by independent scientific organization through periodic and
thorough evaluation of scientific studies. The standards
include a substantial safety margin designed to assure the
safety of all persons, regardless of age and health.
The exposure standard for wireless handsets employs a unit of
measurement known as the Specific Absorption Rate, or SAR.
The SAR limit set by the FCC is 1.6 W/kg. The tests are
performed in positions and locations (e.g. at the ear and worn
on the body) as required by the FCC for each model.
The highest SAR value for this model handset as reported to
the FCC when tested for use at the ear is 0.35 W/kg, and
when worn on the body in a holder or carry case, is 0.35 W/kg.
Body-worn Operation; This device was tested for typical
body-worn operations with the handset kept 1.0 cm from
the body. To maintain compliance with FCC RF exposure
requirements, use accessories that maintain a 1.0 cm
separation distance between the user's body and the handset.
The use of beltclips, holsters and similar accessories should
not contain metallic components in its assembly.
The use of accessories that do not satisfy these requirements
may not comply with FCC RF exposure requirements, and
should be avoided. The FCC has granted an Equipment
Authorization for this model handset with all reported SAR
levels evaluated as in compliance with the FCC RF emission
guidelines. SAR information on this model handset is on
file with the FCC and can be found under the Display Grant
after searching on FCC
