Health and safety
The device meets international guidelines for exposure to
radio waves.
Your device is a radio transmitter and receiver. It’s designed
not to exceed the limits for exposure to radio waves
recommended by international guidelines. The guidelines
were developed by the International Commission on Non-
lonizing Radiation Protection (ICNIRP), an independent
technical standards body, and include margins designed to
assure the safety of all persons, regardless of age and
health. These guidelines use a unit of measurement known
as Specific Absorption Rate (SAR). The SAR limit for mobile
devices is 2.0 W/Kg (Head, Body-worn), 4.0 W/Kg
(Limbs) and the highest SAR value for this device when
tested for use at the head was 1.048 W/Kg, when tested for
use at the body-worn was 0.787 W/Kg and when tested for
use at the limbs was 1.804 W/Kg.
In SAR measurement, the separation distance between the
phone and test device is 5mm.
As SAR is measured when the device is on its highest
transmitting power, the actual SAR of this device while
operating normally is typically below the levels shown
above. This is because the device automatically changes its
power level to ensure it only uses the minimum level
required to reach the network.
The World Health Organization has stated that present
scientific information does not indicate the need for any
special precautions for the use of mobile devices.
Important safety information
For your own health and safety, please follow the radio
frequency (RF) radiation exposure guidelines and keep your
phone no less than 5 mm away from your body.
Failure to do this could mean that your RF exposure
exceeds the guideline limits.
How to limit your radio frequency (RF) exposure
The World Health Organization (WHO) gives the following
advice to people who want to limit their exposure to RF
radiation…
Present scientific information does not indicate the need for
any special precautions for the use of mobile phones. If
individuals are concerned, they may choose to limit their
own or their children’s RF exposure by limiting the length of
calls, or using ‘hands-free’ devices to keep mobile phones
away from the head and body.
Further information on the subject can be obtained from
7
the World Health Organization website at
http://www.who.int/peh-emf WHO Fact sheet 193: June
2000.
1. The tests are carried out in accordance with IEC standard IEC 62209-2.
FCC Regulatory Compliance
FCC Regulations:
interference
This mobile phone has been tested and found to comply with

help.
Caution:
Changes or modifications not expressly approved by Nubia
Technology Co., Ltd. for compliance could void the user‘s
authority to operate the equipment.
RF exposure information (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.
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: 2AHJO-NX669J.
The SAR limit set by the FCC is 1.6 W/Kg.
The highest reported SAR value for this device when using
against the head is less than 1.6 W/Kg, for usage near the body-
worn is less than 1.6 W/Kg(1g-10mm).
Body worn operation
SAR compliance for body-worn operation is based on a
separation distance of 10 mm between the unit and the human
body. Carry this device at least 10 mm away from your body to
ensure RF exposure level compliant or lower to the reported
level. Ensure that the device accessories, such as a device case
and device holster, are not composed of metal components.
Keep the device away from your body to meet the distance
requirement.

Statement of Third-party Applications
During the installation process of some third-party
applications, the issues of repeated restart or abnormal use
of software might be caused by incompatibility of the third-
party applications, rather than the phone itself.
Please download your software upgrade packages from the
reliable official website.
The installation of a third-party ROM or non-official
operating system might bring safety risks and security
threats. Nubia Technology Co., Ltd. shall not be liable for
these risks and threats caused by upgrade of the operating
system.
FCC Hearing-Ai d Compatibility (HAC)
Your phone is compliant with the FCC Hearing Aid Compatibility
requirements.
The FCC has adopted HAC rules for digital wireless phones.
These rules require certain phones to be tested and rated under
the American National Standard Institute (ANSI) C63.19-2011
hearing aid compatibility standards. The ANSI standard for
hearing aid compatibility contains two types of ratings:
• M-Ratings: Rating for less radio frequency interference to
enable acoustic coupling with hearing aids.
• T-Ratings: Rating for inductive coupling with hearing aids in
telecoil mode.
Not all phones have been rated. A phone is considered hearing
aid compatible under FCC rules if it is rated M3 or M4 for
acoustic coupling and T3 or T4 for inductive coupling. These
ratings are given on a scale from one to four, where four is the
most compatible.
