EU Regulations
RED Declaration of Conformity
Xiaomi Communications Co., Ltd. hereby declares that this 2303ERA42L GSM/GPRS/EDGE/UMTS/LTE cell phone with Bluetooth and Wi-Fi complies with the essential requirements and other relevant provisions of Directive 2014/53/EU. The full EU Declaration of Conformity text can be consulted at www.mi.com/en/certification
RF (Radio Frequency) Exposure Information
(SAR — Specific Absorption Rate)
This device complies with the SAR limits for the general
population/uncontrolled exposure (localized SAR of 10 g for the head and
trunk, limit: 2.0 W/kg) specified in Council Recommendation 1999/519/EC, and
the ICNIRP and RED Guidelines (Directive 2014/53/EU).
During SAR testing, this device was set to transmit at its highest certified
power level in all frequency bands tested and placed in positions that
simulate RF exposure during use held directly against the head (no gap) and
close to the body with a gap of 5 mm.
SAR compliance for close-to-body operation is based on there being a 5-mm
separation gap between the device and the human body. This device should be
carried at least 5 mm away from the body to ensure the RF exposure level is at
or lower than the reported level. We recommend using a belt clip or holster
that has no metallic components and that maintains a gap of at least 5 mm
between the device and the body. No metal-containing accessory worn on the
body has been tested or certified as safe for RF exposure, so the use of such
an accessory should be avoided.

FCC Regulations
This cell phone complies with Part 15 of the FCC Rules. Operation is subject
to the following conditions: (1) This device may not cause harmful
interference and (2) this device must accept any interference received,
including interference that may cause undesired operation.
This cell phone has been tested and found to comply with the limits for a
Class B digital device, under Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used by the instructions, may cause
harmful interference with radio communications. However, there is no guarantee
that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by taking one or more of the
following measures:
- Reorient or relocate the receiving antenna.

- Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
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 RF energy. The exposure standard for wireless devices employs a
unit of measurement known as the Specific Absorption Rate or SAR. The SAR
limit set by the FCC is 1.6 W/kg. For use with a wearable accessory, this
device has been tested and found to comply with the FCC RF exposure guidelines
for use with a metal-free accessory that positions the device at least 1.5 cm
(5/8 inch) away from the body. No metal-containing accessory worn on the body
has been tested or certified as safe for RF exposure, so the use of such an
accessory should be avoided. Accessories are commercially available and must
be used to maintain a distance of at least 1.5 cm (5/8 inch) between the EUT
device and the body.
