RED Declaration of Conformity
Xiaomi Communications Co., Ltd. hereby declares that this GSM / GPRS /
EDGE / UMTS / LTE Digital Mobile Phone with Bluetooth and Wi-Fi
M2010J19SL is in compliance with the essential requirements and other
relevant provisions of the RE Directive 2014/53/EU. The full text of the EU
declaration of conformity is available at the following internet address:
www.mi.com/en/certification
RF Exposure Information (SAR)
This device is in compliance with Specific Absorption Rate (SAR) limits for
general population/uncontrolled exposure (Localized 10-gram SAR for head
and trunk, limit: 2.0W/kg) specified in Council Recommendation 1999/519/EC,
ICNIRP Guidelines, and RED (Directive 2014/53/EU).
During SAR testing, this device was set to transmit at its highest certified
power level in all tested frequency bands and placed in positions that
simulate RF exposure during use against the head with no separation and
near the body with a separation of 5 mm.
SAR compliance for body operation is based on a separation distance of 5 mm
between the unit and the human body. This device should be carried at least
5 mm away from the body to ensure RF exposure level is compliant or lower
than the reported level. When attaching the device near the body, a belt clip
or holster should be used which does not contain metallic components and
allows a separation of at least 5 mm to be maintained between the device
and the body. RF exposure compliance was not tested or certified with any
accessory containing metal worn on the body, and use of such an accessory
should be avoided.
Certification Information (Highest SAR)
SAR 10 g limit: 2.0 W/Kg,
SAR Value: Head: 0.593 W/Kg, Body: 0.898 W/Kg (5 mm distance).
Legal Information
This device may be operated in all member states of the EU.

RF Exposure Information (SAR)
This device meets the government’s requirements for exposure to radio
waves. This device is designed and manufactured not to exceed the emission
limits for exposure to radio frequency (RF) energy. The exposure standard
for wireless devices employs a unit of measurement known as Specific
Absorption Rate, or SAR.
The SAR limit set by the FCC is 1.6 W/Kg. For body-worn operation, this device
has been tested and meets the FCC RF exposure guidelines for use with an
accessory that contains no metal and positions the device a minimum of
1.5 cm from the body. RF exposure compliance with any body-worn accessory
that contains metal was not tested and certified, and use of such body-worn
accessory should be avoided. Any accessory used with this device for
body-worn operation must keep the device a minimum of 1.5 cm away from
the body.
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
This device has an electronic label for certification information.
