Specific Absorption Rate (SAR) of Mobile Phones
This model N-04C 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 0.469 W/kg. 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.

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 present scientific information does not
indicate that there are harmful effects attributed to the use of mobile devices. They
recommend that if you are worried about your exposure then you can limit your usage or simply
use a hands-free kit to keep the mobile device away from the head and body.
Please refer to the WHO website if you would like more detailed information.
