(In English)
This model [SC-04G] mobile phone complies with Japanese technical regulations and international
guidelines regarding exposure to radio waves.
This mobile phone was designed in observance of Japanese technical regulations regarding exposure to radio
waves (*1) and limits to exposure to radio waves recommended by a set of equivalent international guidelines.
This set of international guidelines was set out by the International Commission on Non-Ionizing Radiation
Protection (ICNIRP), which is in collaboration with the World Health Organization (WHO), and the permissible
limits include a substantial safety margin designed to assure the safety of all persons, regardless of age and
health condition.
The technical regulations and international guidelines set out limits for radio waves as the Specific Absorption
Rate, or SAR, which is the value of absorbed energy in any 10 grams of tissue over a 6-minute period. The SAR
limit for mobile phones is 2.0 W/kg. The highest SAR value for this mobile phone when tested for use at the ear
is 0.210 W/kg (*2) and when worn on the body is 0.665 W/kg (*3). There may be slight differences between
the SAR levels for each product, but they all satisfy the limit.
The actual SAR of this mobile phone while operating can be well below that indicated above. This is due to
automatic changes to the power level of the device to ensure it only uses the minimum required to reach the
network. Therefore in general, the closer you are to a base station, the lower the power output of the device.
This mobile phone can be used in positions other than against your ear. Please keep the mobile phone farther
than 1.5 cm away from your body by using such as a carrying case or a wearable accessory without including any
metals. This mobile phone satisfies the technical regulations and international guidelines.
The World Health Organization has stated 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."
Please refer to the WHO website if you would like more detailed information.

*1 Technical regulations are defined by the Ministerial Ordinance Related to Radio Law (Article 14-2 of Radio
2
Equipment Regulations).
*2 In regards to methods of measuring SAR when using mobile phones having multiple wireless devices to be
able to function simultaneously at the ear, in July of 2015, a portion of advisory 118 was reported on based upon
the Information and Communications Council. SAR value when evaluated based on the report is also under the
SAR limit.
*3 Including other radio systems that can be simultaneously used with Xi/FOMA.

2. About SAR of SC-04G for FCC RF exposure requirements
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 organisations 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 values for this model handset when tested for use at the ear is 1.21 W/kg and
when worn on the body, as described in this user guide, is 1.25 W/kg.
Body-worn Operation
For body worn operation, this phone has been tested and meets the FCC RF exposure guidelines. Please use an
accessory designated for this product or an accessory which contains no metal and which positions the handset
a minimum of 1.5 cm from the body.
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 section of http://transition.fcc.gov/oet/ea/fccid/ after searching
on FCC ID A3LSC04G.
Additional information on Specific Absorption Rates (SAR) can be found on the Cellular Telecommunications &
Internet Association (CTIA) Website at http://www.ctia.org/.

3. About SAR of SC-04G for EU RF exposure requirements
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 W/kg and the highest SAR value for this device when tested at the ear was 0.301 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 0.445 W/kg.
As SAR is measured utilizing the devices highest transmitting power the actual SAR of this device while operating
is typically below that indicated above. This is due to automatic changes to the power level of the device to
ensure it only uses the minimum level required to reach the network.
