Specific Absorption Rate (SAR)
certification information
THIS DEVICE MEETS INTERNATIONAL GUIDELINES
FOR EXPOSURE TO RADIO WAVES
Your mobile 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
(ICNIPP) 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 European Union SAR limit for mobile devices is
2.0W/kg averaged over 10 grams of tissue. The India SAR
limit for mobile devices is 1.6W/kg averaged over 1 grams
of tissue.
The highest SAR value for your Lenovo device when
tested for use at the head and body is outlined as follows:
Position SAR(W/kg) for 1
g SAR(W/kg)
for 10 g
Head 0.609 0.35
Body-worn 0.544 0.384
During use, the actual SAR values for this device are
usually well below the values stated above. This is
because, for purposes of system efficiency and to
minimize interference on the network, the operating power
