WARNING : Cancer and Reproductive Harm –www.P65Warnings.ca.gov
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-ionizing 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
FCC Regulations
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 radiate 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.
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 radiofrequency (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 the RF exposure level is 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.
