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 | 0.153 W/kg |
| Body-worn | Wi-Fi, Bluetooth |
0.448 W/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.
