Exposure to radio frequency energy
This device has been designed to comply with applicable safety requirements
for exposure to radio waves. These requirements are based on scientic
guidelines that include safety margins 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
Specic Absorption Rate, or SAR. Tests for SAR using standardised methods
with the device transmitting at its highest certied power level in all used
frequency bands.
The International Commission on Non-Ionizing Radiation Protection (ICNIRP)
recommends a limit for SAR: it’s 2 watts per kilogram (W/kg) averaged over
10 grams (g) of tissue.
The highest SAR values for this model when it was tested were:
Maximum 10g SAR(W/kg)
Band Body (15mm) Body (5mm)
LTE Band III 0.84 1.81
