Parliament’s RoHS (Restriction of Hazardous
Substances) Directive 2002/95/EC, with respect to all
the following substances:
(1) Lead (Pb)
(2) Mercury (Hg)
(3) Cadmium (Cd)
(4) Hexavalent Chromium (Cr (VI))
(5) Polybrominated biphenyl (PBB)
(6) Polybrominated diphenyl ether (PBDE)
Our compliance is witnessed by written declaration
from our suppliers. This confirms that any potential
trace contamination levels of the substances listed
above are below the maximum level set by EU
2002/95/EC, or are exempt due to their application.
The NX531J manufactured by Nubia Technology Co.,

FCC Regulations:
This mobile phone complies with part 15 of the FCC
Rules. Operation is subject to the following two
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 mobile phone has been tested and found to
comply with the limits for a Class B digital device,
pursuant to 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 radiated radio
frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful
interference to 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 one or more of the
following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and
receiver.
-Connect the equipment into 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.
FCC Note:
Caution: Changes or modifications not expressly
approved by the party responsible 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.
During SAR testing, this device was set to transmit at

7
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 10 mm. Although the SAR is 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 1.6W/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. This device has
been tested and meets the FCC RF exposure
guidelines when tested with the device directly
contacted to the body.
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-NX531J.
For this device, the highest reported SAR value for
usage against the head is 0.499W/kg, for usage near
the body is 0.652W/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 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. To support
body-worn operation, choose the belt clips or
holsters, which do not contain metallic components,
to maintain a separation of 10 mm between this
device and your body.

8
RF exposure compliance with any body-worn
accessory, which contains metal, was not tested and
certified, and use such body-worn accessory should
be avoided.
