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-8504F
Head Wi-Fi, Bluetooth 0.153W/kg
Body-worn Wi-Fi, Bluetooth 0.448W/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 head
and body.
