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.

Europe 
10g SAR 
Limit (2.0 
W/kg)

Lenovo TB-
8604F

Body-worn

Wi-Fi, Bluetooth

0.991W/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 using a hands-free kit to keep the device away 
from the body.
