Specific Absorption Rate (EU SAR)
Your mobile device is a radio transmitter and receiver. It
is designed not to exceed the limits for exposure to radio
waves recommended by international guidelines. These
guidelines were developed by the independent scientific
organization ICNIRP and include safety margins designed
to assure the protection of all persons, regardless of age
and health.
The guidelines use a unit of measurement known as
Specific Absorption Rate, or SAR. The SAR limit for
mobile devices is 2 W/kg and the highest SAR value for
this device when tested at the head was 0.339 W/kg*, and
when tested at the body was 1.614W/kg* with 5 mm
distance. As mobile devices offer a range of functions,
they can be used in other positions, such as on the body
as described in the user manual**.
As SAR is measured utilizing the device’s highest
transmitting power, the actual SAR of this device while
operating is typically below that indicated above.This is
due to automatic changes to the power level of the
device to ensure it only uses the minimum power
required to communicate with the network.
11
* The tests are carried out in accordance with EN 50360,
EN 50566, EN50663, EN 62209-1 and EN 62209-2.
** Please see body worn operation in the user manual.

Hereby, ZTE Corporation declares that the radio
equipment type ZTE Blade A51 is in compliance with
Directive 2014/53/EU.
The full text of the EU declaration of conformity is
available at the following Internet address:
https://certification.ztedevices.com
ErP Conformity
The external power supply of this product conforms to

RF Exposure Information (FCC SAR)
This phone is designed and manufactured not to exceed
the emission limits for exposure to radio frequency (RF)
energy set by the Federal Communications Commission
of the United States.
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 in
usage against the head with no separation, and near the
body with the separation of 15 mm. Although the SAR is
15
determined at the highest certified power level, the
actual SAR level of the device while operating can be well
below the maximum value.This is because the phone is
designed to operate at multiple power levels so as to use
only the power required to reach the network. In general,
the closer you are to a wireless base station antenna, the
lower the power output.
The exposure standard for wireless devices employing a
unit of measurement is known as the Specific Absorption
Rate, or SAR.The SAR limit set by the FCC is 1.6 W/kg.
This device is complied with SAR for general
population/uncontrolled exposure limits in ANSI/IEEE
C95.1-1992 and had been tested in accordance with the
measurement methods and procedures specified in
IEEE1528.
The FCC has granted an Equipment Authorization for this
model phone with all reported SAR levels evaluated as in
compliance with the FCC RF exposure guidelines. SAR
information on this model phone is on file with the FCC
and can be found under the Display Grant section of
www.fcc.gov/oet/ea/fccid after searching on FCC ID:
SRQ-ZTEA51V. The FCC ID also can be found on the
device when you open Settings >About phone > FCC ID.
For this device, the highest reported SAR value for usage
against the head is 0.651 W/kg, and for usage near the
body is 0.823 W/kg.
While there may be differences between the SAR levels
of various phones and at various positions, they all meet
the government requirements.
SAR compliance for body-worn operation is based on a
16
separation distance of 15 mm between the unit and the
human body. Carry this device at least 15 mm away from
your body to ensure RF exposure level compliant or lower
to the reported level. To support body-worn operation,
choose the belt clips or holsters, which do not contain
metallic components, to maintain a separation of 15 mm
between this device and your body.
RF exposure compliance with any body-worn accessory,
which contains metal, was not tested and certified, and
using such body-worn accessory should be avoided.
