Specific Absorption Rate information
YOUR MOBILE 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 elds)
recommended by international guidelines. The guidelines were developed by an
independent scientic 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
Specic Absorption Rate, or SAR. The SAR limit for mobile devices is 2W/kg.
Tests for SAR are conducted using standard operating positions with the device
transmitting at its highest certied power level in all tested frequency bands. The
highest SAR values under the ICNIRP guidelines for your device model are listed
below:
Maximum SAR for this model and conditions under which it was recorded.

Wi-Fi, Bluetooth
1.585W/kg
Lenovo
YB-J912F
Body-worn Wi-Fi, Bluetooth 1.536W/kg
During use, the actual SAR values for your device are usually well below the
values stated. This is because, for purposes of system efciency 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 using a hands-free kit to keep the device away
from the head and body.
