your service provider for more information.
• Pacemaker manufacturers recommend that a minimum distance of 15 cm be maintained
between a device and a pacemaker to prevent potential interference with the pacemaker. If
using a pacemaker, hold the device on the side opposite the pacemaker and do not carry
the device in your front pocket.
Protecting your hearing when using a headset
• Do not place sharp metal objects, such as pins, near the earpiece or speaker. The earpiece
may attract these objects and result in injury.
• Stop using your device or applications for a while if the device is overheated. If skin is exposed
to an overheated device for an extended period, low temperature burn symptoms, such as
red spots and darker pigmentation, may occur.
• Do not use your device’s camera flash directly in the eyes of people or pets. Otherwise
temporary loss of vision or damage to the eyes may occur.

Battery Caution
FCC Statement
1. Use only NUU-approved batteries, chargers, and cables to charge your phone.
Unapproved chargers or cables can cause the battery to explode or damage the device.
two conditions:
2. Use only NUU-approved batteries, chargers and cables. Use of unapproved batteries,
chargers and cables may cause safety issues and the warranty will be cancelled.
3. You can recharge your battery many times, but all batteries have a limited lifespan.
If you notice a significant deterioration in your phone’s battery life, you will need to
purchase a replacement battery for replacement. If the battery is built in the phone, do
not attempt to remove built-in batteries and contact an authorized NUU service center
for a replacement.
4. Your phone may become warm after prolonged use or when exposed to high ambient
temperatures. If your phone becomes hot to the touch, unplug the USB cable, disable
non-essential features, and avoid prolonged skin contact. Place your phone in a cool
location and allow it to cool down to room temperature.
5. Charging times may vary depending on the ambient temperature and the remaining

when it is charging.
1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following
(1) This device may not cause harmful interference.
(2) This device must accept any interference received, including interference that may
cause undesired operation.
2. Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
NOTE:
This equipment 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.

SAR Information Statement
Body-worn Operation
This device was tested for typical body-worn operations. To comply with RF exposure
requirements, a minimum separation distance
of 10mm must be maintained between the user’s body and the handset, including the
antenna. Third-party belt-clips, holsters,
and similar accessories used by this device should not contain any metallic components.
Body-worn accessories that do not meet these requirements may not comply with RF
exposure requirements and should be avoided. Use only the supplied or an approved
antenna.
Your Smart Phone is a radio transmitter and receiver. It is designed and manufactured
not to exceed the emission limits for exposure to radiofrequency (RF) energy set by the
Federal Communications Commission of the U.S. Government. These limits are part of
comprehensive guidelines and establish permitted levels of RF energy for the general
population. The guidelines are based on standards that were developed by independent
scientific organizations through periodic and thorough evaluation of scientific studies. The
standards include a substantial safety margin designed to assure the safety of all persons,
regardless of age and health. The exposure standard for wireless mobile phones 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. * Tests for SAR are conducted with the phone transmitting
at its highest certified power level in all tested frequency bands. Although the SAR is
determined at the highest certified power level, the actual SAR level of the phone 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. Before a phone model is available for sale to the public, it must be tested
and certified to the FCC that it does not exceed the limit established by the government
adopted requirement for safe exposure. The tests are performed in positions and locations
(e.g., at the ear and worn on the body) as required by the FCC for each model. The
highest SAR value for this model phone when tested for use at the ear is 0.574W/Kg
and when worn on the body, as described in this user guide, is 0.619W/Kg(Body-worn
measurements differ among phone models, depending upon available accessories and
FCC requirements). The maximum scaled SAR in hotspot mode is 0.779W/Kg. While there
may be differences between the SAR levels of various phones and at various positions,
they all meet the government requirement for safe exposure. The FCC has granted an
Equipment Authorization for this model phone with all reported SAR levels evaluated as in
compliance with the FCC RFexposure guidelines. SAR information on this model phone is
on file with the FCC and can be found under the Display Grant section of http://www.fcc.
gov/ oet/fccid after searching on
FCC ID: 2ADINS6701L Additional information on Specific Absorption Rates (SAR) can be
found on the Cellular Telecommunications Industry Asso-ciation (CTIA) web-site at http://
www.wow-com.com. * In the United States and Canada, the SAR limit for mobile phones
used by the public is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The standard
incorporates a sub-stantial margin of safety to give additional protection for the public and
to account for any variations in measurements.
