RF Exposure Information/Specific
Absorption Rate (SAR) Information
"802SO" here refers to this mobile phone "Xperia 1."
Specific Absorption Rate (SAR) for This
Product (for Japan)
This mobile phone 802SO meets Japanese technical
regulations* and international guidelines for exposure to radio
waves.
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 regulations employ 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 1.73 W/kg***
when tested for use at the ear, and 0.75 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.
* The technical regulations are provided in Article 14-2 of the
Ministry Ordinance Regulating Radio Equipment.
** International Commission on Non-Ionizing Radiation
Protection
*** The value is under simultaneous transmission use
conditions.
****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 it and the body and the mobile phone, this mobile
phone will comply with international guidelines for radio wave
protection.
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." They note
that if you want to reduce your exposure then you can do so
by limiting the length of calls or using a hands-free device to
keep the mobile phone away from the head and body.

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 0.39 W/kg*. As mobile devices offer a
range of functions, they can be used in other positions, such
as on the body. In this case, the highest tested SAR value is
1.02 W/kg* at the separation distance of 0.5 cm from the
body. For electronic safety, maintain the separation distance
with accessories containing no metal, that position handset a
minimum of the above distance. Use of other accessories may
not ensure compliance with RF exposure guidelines.
* The tests are carried out in accordance with international
guidelines for testing.
