Specific Absorption Rate (ICNIRP)
YOUR DEVICE MEETS INTERNATIONAL
GUIDELINES FOR EXPOSURE TO RADIO WAVES.
Your device is a radio transmitter and receiver. It is
designed not to exceed the limits for exposure to
radio waves (radio frequency electromagnetic
fields) recommended by international guidelines.
The guidelines were developed by an independent
scientific organization (ICNIRP) and include a
substantial safety margin designed to assure the
safety of all persons, regardless of age and health.
The radio wave exposure guidelines use a unit of
measurement known as the Specific Absorption
Rate, or SAR. The Europe 10g SAR limit for mobile
devices is 2.0 W/kg. Tests for SAR are conducted
using standard operating positions with the device
transmitting at its highest certified power level in
all tested frequency bands. The highest SAR values
under the ICNIRP guidelines for your device are as
follows:
Maximum body-worn SAR with 0 mm separation
distance: 1.571 W/kg
During use, the actual SAR values for your device
are usually well below the values stated. This is
because, for purposes of system efficiency and to
minimize interference on the network, the
operating power of your mobile device is
automatically decreased when full power is not
needed for the data connection. The lower the
power output of the device, the lower its SAR
value.
If you are interested in further reducing your RF
exposure then you can easily do so by limiting your
usage or simply keeping the device away from the
body.
European Union — compliance with

Rata specifică de absorbţie (ICNIRP)
DISPOZITIVUL DUMNEAVOASTRĂ RESPECTĂ
REGULILE INTERNAȚIONALE PRIVIND
EXPUNEREA LA UNDELE RADIO.
Dispozitivul dumneavoastră este un transmiţător și
un emiţător radio. Acest dispozitiv este conceput
să nu depășească limitele de expunere la undele
radio (câmpuri electromagnetice de frecvenţă
radio), recomandate de regulile internaţionale.
Regulile au fost concepute de o organizaţie
știinţifică independentă (ICNIRP) și includ o marjă
de siguranţă considerabilă creată pentru a asigura
siguranţa tuturor persoanelor, indiferent de vârstă
și de starea de sănătate.
Regulile privind expunerea la undele radio
utilizează ca unitate de măsura rata specifică de
absorbţie, denumită și SAR. Limita SAR 10g în
Europa pentru dispozitive mobile este de 2,0
W/kg. Testele pentru SAR sunt efectuate utilizând
poziţiile de operare standard, cu dispozitivul
transmiţând la nivelul său de putere certificat cel
mai înalt, în toate benzile de frecvenţă testate. Cele
mai mari valori SAR prevăzute în regulile ICNIRP
pentru dispozitivul dumneavoastră sunt după cum
urmează:
Limita maximă SAR pentru dispozitive purtate
asupra corpului la o distanţă minimă de 0 mm:
1,571 W/kg
