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 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 SAR limit for mobile devices is 2W/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 model are listed
below:
Maximum SAR for this model and conditions under which it was recorded.

Lenovo XXXX Head LTE band38,
WLAN, Bluetooth

Body-worn LTE band38,
WLAN, Bluetooth
XX.XX
Lenovo XXXX Head WLAN, Bluetooth XX.XX
Body-worn WLAN, Bluetooth XX.XX
During use, the actual SAR values for your device are usually well below the
values stated. This is because, for purposes of system e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.
