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 1.2 W/kg.
There may be slight differences between the
SAR levels for each product, but they all
satisfy the limit.
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 or the
manufacturer
*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."
