Appendix/Index
This model SH-04D 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/k
g
. The highest SAR value for this
mobile phone when tested for use at the ear is
0.817 W/k
g
. 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. This mobile phone satisfies
the international guidelines when used with a
carrying case or a wearable accessory approved by
NTT DOCOMO, INC. (*2). In case you are not
using the approved accessory, please use a
product that does not contain any metals, and one
that positions the mobile phone at least 1.5 cm
away from your body.
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.
