The full text of the EU declaration of conformity is available at: www.mi.com/en/certification

RF Exposure Information (SAR)

This device complies with Specific Absorption Rate (SAR) limits for general population/uncontrolled exposure (Localized 10-gram SAR for head and trunk, limit: 2.0W/kg) as specified by Council Recommendation 1999/519/EC, ICNIRP Guidelines, and RED (Directive 2014/53/EU).

During SAR testing, the device was set to transmit at its highest certified power level in all tested frequency bands and placed in positions simulating RF exposure against the head (no separation) and near the body (5 mm separation).

SAR compliance for body operation is based on a separation distance of 5 mm. The device should be carried at least 5 mm away from the body to ensure RF exposure levels are compliant. When carrying the device near the body, use a belt clip or holster without metallic components that maintains at least 5 mm separation. RF exposure compliance with body-worn accessories containing metal has not been tested or certified, and such accessories should be avoided. Any accessory used for body-worn operation must keep the device at least 1.0 cm away from the body.

Certification Information (Highest SAR):

SAR 10 g limit: 2.0 W/Kg. SAR Value: Head: 0.795 W/Kg, Body: 1.138 W/Kg (5 mm distance).
