Maintaining Safe Use of and Access to
Your Phone
Do Not Rely on Your Phone for Emergency Calls
Mobile phones operate using radio signals, which
cannot guarantee connection in all conditions.
Therefore you should never rely solely upon any mobile
phone for essential communication (e.g., medical
emergencies). Emergency calls may not be possible on
all cellular networks or when certain network services or
mobile phone features are in use. Check with your local
service provider for details.
Using Your Phone While Driving
Talking on your phone while driving (or operating the
phone without a hands-free device) is prohibited in
some jurisdictions. Laws vary as to speciic restrictions.
Remember that safety always comes irst.
Following Safety Guidelines
To operate your phone safely and eficiently, always
follow any special regulations in a given area. Turn your
phone off in areas where use is forbidden or when it may
cause interference or danger.
Using Your Phone Near Other Electronic Devices
Most modern electronic equipment is shielded from
radio frequency (RF) signals. However, RF signals from
wireless phones may affect inadequately shielded
electronic equipment.
RF signals may affect improperly installed or
inadequately shielded electronic operating systems or
entertainment systems in motor vehicles. Check with
the manufacturer or their representative to determine if
these systems are adequately shielded from external RF
signals. Also check with the manufacturer regarding any
equipment that has been added to your vehicle.
Consult the manufacturer of any personal medical
devices, such as pacemakers and hearing aids, to
determine if they are adequately shielded from external
RF signals.
Note: Always turn off the phone in healthcare facilities,
and request permission before using the phone
near medical equipment.
Turning Off Your Phone Before Flying
Turn off your phone before boarding any aircraft. To
prevent possible interference with aircraft systems, the
U.S. Federal Aviation Administration (FAA) regulations
require you to have permission from a crew member
to use your phone while the plane is on the ground.
To prevent any risk of interference, FCC regulations
prohibit using your phone while the plane is in the air.
Turning Off Your Phone in Dangerous Areas
To avoid interfering with blasting operations, turn your
phone off when in a blasting area or in other areas
with signs indicating two-way radios should be turned
off. Construction crews often use remote-control RF
devices to set off explosives.
Turn your phone off when you’re in any area that has a
potentially explosive atmosphere. Although it’s rare,
your phone could generate sparks. Sparks can cause an
explosion or ire, resulting in bodily injury or even death.
These areas are often, but not always, clearly marked.
They include:
• Fueling areas such as gas stations.
• Below deck on boats.
• Fuel or chemical transfer or storage facilities.
• Areas where the air contains chemicals or particles
such as grain, dust, or metal powders.
• Any other area where you would normally be advised
to turn off your vehicle’s engine.
4Important Safety InformationImportant Safety Information 5
Note: Never transport or store lammable gas,
lammable liquids, or explosives in the
compartment of your vehicle that contains your
phone.
Restricting Children’s Access to Your Phone
Your phone is not a toy. Do not allow children to play with
it as they could hurt themselves and others, damage the
phone or make calls that increase your Sprint invoice.
Using Your Phone With a Hearing Aid
Device
A number of Sprint phones have been tested for hearing
aid device compatibility. When some wireless phones
are used with certain hearing devices (including hearing
aids and cochlear implants), users may detect a noise
which can interfere with the effectiveness of the hearing
device.
Some hearing devices are more immune than others
to this interference noise, and phones also vary in
the amount of interference noise they may generate.
ANSI standard C63.19 was developed to provide a
standardized means of measuring both wireless phone
and hearing devices to determine usability rating
categories for both.
Ratings have been developed for mobile phones to
assist hearing device users ind phones that may be
compatible with their hearing device. Not all phones
have been rated for compatibility with hearing devices.
Phones that have been rated have a label located on the
box.
These ratings are not guarantees. Results will vary
depending on the user’s hearing device and individual
type and degree of hearing loss. If a hearing device is
particularly vulnerable to interference noise; even a
phone with a higher rating may still cause unacceptable
noise levels in the hearing device. Trying out the phone
with your hearing device is the best way to evaluate it for
your personal needs.
M-Ratings: Phones rated M3 or M4 meet FCC
requirements for hearing aid compatibility and are likely
to generate less interference to hearing devices than
unrated phones. (M4 is the better/higher of the two
ratings.)
T-Ratings: Phones rated T3 or T4 meet FCC requirements
and are likely to be more usable with a hearing device’s
telecoil (“T Switch” or “Telephone Switch”) than unrated
phones. (T4 is the better/higher of the two ratings. Note
that not all hearing devices have telecoils in them.)
Note: New Technologies, Including VoIP over Wi-Fi
or LTE
This phone has been tested and rated for use
with hearing aids for some of the wireless
technologies that it uses. However, there may
be newer wireless technologies (including VoIP
over Wi-Fi or LTE) used in this phone that have not
been tested for use with hearing aids.
Hearing aid devices may also be measured for immunity
to interference noise from wireless phones and should
have ratings similar to phones. Ask your hearing
healthcare professional for the rating of your hearing
aid. Add the rating of your hearing aid and your phone to
determine probable usability:
• Any combined rating equal to or greater than six
offers excellent use.
• Any combined rating equal to ive is considered
normal use.
• Any combined rating equal to four is considered
usable.
Thus, if you pair an M3 hearing aid with an M3 phone,
you will have a combined rating of six for “excellent use.”
This is synonymous for T ratings.
6Important Safety InformationImportant Safety Information 7
Sprint further suggests you experiment with multiple
phones (even those not labeled M3/T3 or M4/T4)
while in the store to ind the one that works best with
your hearing aid device. Should you experience
interference or ind the quality of service unsatisfactory
after purchasing your phone, promptly return it to
the store within 14 days of purchase. (A restocking
fee may be applied to exchanges. Visit
returns
for details.) More information about hearing aid
compatibility may be found at:

Radio Frequency (RF) Energy
Understanding How Your Phone Operates
Your phone is basically a radio transmitter and receiver.
When it’s turned on, it receives and transmits radio
frequency (RF) signals. When you use your phone, the
system handling your call controls the power level. This
power can range from 0.006 watt to 0.2 watt in digital
mode.
Knowing Radio Frequency Safety
The design of your phone complies with updated NCRP
standards described below.
In 1991–92, the Institute of Electrical and Electronics
Engineers (IEEE) and the American National Standards
Institute (ANSI) joined in updating ANSI’s 1982 standard
for safety levels with respect to human exposure to
RF signals. More than 120 scientists, engineers and
physicians from universities, government health
agencies and industries developed this updated
standard after reviewing the available body of research.
In 1993, the Federal Communications Commission (FCC)
adopted this updated standard in a regulation. In August
1996, the FCC adopted hybrid standard consisting of
the existing ANSI/IEEE standard and the guidelines
published by the National Council of Radiation
Protection and Measurements (NCRP).

Body-Worn Operation
This device was SAR tested for typical body-worn
operations with the phone kept
When operating with “Hotspot” functionality engaged,
a separation distance of
compliance with FCC RF exposure requirements, use
only belt-clips, holsters or similar accessories that
maintain a
user’s body and the phone, including the antenna.
The use of belt-clips, holsters and similar accessories
should not contain metallic components in its assembly.
The use of accessories that do not satisfy these
requirements may not comply with FCC RF exposure
requirements, and should be avoided.
For more information about RF exposure, visit the FCC

1.0 cm was used. To maintain
Speciic Absorption Rates (SAR) for Wireless
Phones
The SAR value corresponds to the relative amount of RF
energy absorbed into the head of a user of a wireless
phone.
The SAR value of a phone is the result of an extensive
testing, measuring and calculation process. It does
not represent how much RF the phone emits. All
phone models are tested at their highest value in
strict laboratory settings. But when in operation, the
SAR of a phone can be substantially less than the level
reported to the FCC. This is because of a variety of
factors including its proximity to a base station antenna,
phone design and other factors. What is important
to remember is that each phone meets strict federal
guidelines. Variations in SARs do not represent a
variation in safety.
All phones must meet the federal standard, which
incorporates a substantial margin of safety. As stated
above, variations in SAR values between different model
phones do not mean variations in safety. SAR values at
or below the federal standard of 1.6 W/kg are considered
safe for use by the public.
The highest reported SAR values of the AQUOS Crystal
are:
This phone meets the FCC Radio Frequency Emission
Guidelines.
