Lenovo YT-J706F Safety, Warranty & Quick Start Manual page 13

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.
