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: 0.32 W/kg (Lenovo ThinkBook 13s-IWL),
0.17 W/kg (Lenovo ThinkBook 14s-IWL)
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 the
Radio Equipment Directive

Specifik absorptionshastighed (ICNIRP)
DIN ENHED OPFYLDER DE INTERNATIONALE
RETNINGSLINJER FOR EKSPONERING FOR
RADIOBØLGER.
Din enhed er en radiosender og -modtager. Den er
designet til ikke at overskride de grænser for
eksponering for radiobølger (elektromagnetiske
stråler), som anbefales af internationale forskrifter.
Forskrifterne er udarbejdet af en uafhængig
videnskabelig organisation (ICNIRP) og indeholder
en væsentlig sikkerhedsmargen, der er beregnet til
at sørge for sikkerheden for alle personer,
uafhængigt af alder og helbredstilstand.
Forskrifterne vedrørende eksponering for
radiobølger anvender en måleenhed, der kaldes
Specifik absorptionshastighed eller SAR. Europa-
10g SAR-grænsen for mobilenheder er 2,0 W/kg.
Tests for SAR udføres ved hjælp af
standardbetjeningspositioner, hvor enheden sender
med det højest certificerede strømniveau på alle
testede frekvensbånd. De højeste SAR-værdier i
henhold til ICNIRP-forskrifterne for din enhed er
som følger:
Maksimal SAR, der bæres på kroppen med 0 mm
afstand: 0,32 W/kg (Lenovo ThinkBook 13s-IWL),
0,17 W/kg (Lenovo ThinkBook 14s-IWL)
Under brug er de faktiske SAR-værdier for din
enhed normalt et godt stykke under de værdier, der
er angivet. Dette skyldes, at af hensyn til
systemeffektivitet og for at minimere interferens på
netværket reduceres driftsstrømmen for din
mobilenhed automatisk, når der ikke er brug for
fuld strøm til dataforbindelsen. Jo lavere
strømoutputtet er for enheden, jo lavere er dens
SAR-værdi.
Hvis du er interesseret i at reducere din
eksponering for radiofrekvensstråling, kan du nemt
gøre det ved at begrænse din brug eller ved blot at
holde enheden væk fra kroppen.
