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.
Important Safety Information 3
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 specific restrictions.
Remember that safety always comes first.
Tip: Purchase an optional hands-free accessory
at your local Sprint Store, or call Sprint at
1-866-866-7509. You can also dial
your phone.

Following Safety Guidelines
To operate your phone safely and efficiently, 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
4 Important Safety Information
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 of f 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 and accessories could generate sparks.
Sparks can cause an explosion or fire, 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.
Important Safety Information 5
● Any other area where you would normally be
advised to turn off your vehicle’s engine.
Note: Never transport or store flammable gas,
flammable liquids, or explosives in the
compartment of your vehicle that contains your
phone or accessories.
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.
Water Resistance
Your DuraMax is water-resistant. To ensure that your
phone maintains water resistance, the following
precautions must be observed.
● Make sure the battery cover is properly attached
and locked.
● Make sure the charger/accessory jack and the
headphone jack are properly sealed, with no foreign
objects obstructing the seals.
Warning: Your phone is designed to withstand
● Do not expose your phone to water heated in
excess of 104° F (40° C), or to liquids other than
water, such as detergent, beverages, or chlorinated
or treated water.
Charging
Dry your phone with a clean cloth before charging.
●
● Do not touch the charger, charging cable, or
charger/accessory jack with wet hands. Doing so
may cause electric shock, injury, or product failure.
● Do not charge your phone in a wet or damp place,
such as in a bathroom or near a kitchen sink.
6 Important Safety Information
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
exposure to water for up to 30 minutes at a
depth not exceeding one meter (about 3.25
feet). Exposing your phone to water outside
these limits or not following the above
precautions can result in water damage.
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 find 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
Your DuraMax has an M4 and a T4 rating.
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
Important Safety Information 7
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 Wi-Fi
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 Wi-Fi)
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 five 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.
Sprint further suggests you experiment with multiple
phones (even those not labeled M3/T3 or M4/T4)
while in the store to find the one that works best with
your hearing aid device. Should you experience
interference or find the quality of service unsatisfactory
after purchasing your phone, promptly return it to the
8 Important Safety Information
store within 30 days of purchase. (A restocking fee may
be applied to exchanges. Visit
for details.) More information about hearing aid
compatibility may be found at:
www.fda.gov, and www.accesswireless.org.
Getting the Best Hearing Device Experience
With Your Phone
To further minimize interference:
● Set the phone’s display and keypad backlight
settings to ensure the minimum time interval:
1. Press > Settings > Display > Backlight >
Backlight Dim
2. Highlight the minimum time interval setting and

or Backlight Off.
● Move the phone around to find the point with least
interference.
Caring for the Battery
Protecting Your Battery
The guidelines listed below help you get the most out
of your battery’s performance.
● Recently there have been some public reports of
wireless phone batteries overheating, catching fire,
or exploding. It appears that many, if not all, of these
reports involve counterfeit or inexpensive,
aftermarket-brand batteries with unknown or
questionable manufacturing standards. Sprint is not
aware of similar problems with Sprint phones
resulting from the proper use of batteries and
accessories approved by Sprint or the manufacturer
of your phone. Use only Sprint-approved or
manufacturer-approved batteries and accessories

other hazard.
● Avoid dropping the phone or battery. If the phone or
battery is dropped, especially on a hard surface,
and the user suspects damage, take it to a service
center for inspection.
● Improper battery use may result in a fire, explosion
or other hazard.
www.sprint.com/accessories.
● Do not short-circuit a battery or allow metallic
conductive objects to contact battery terminals.
● Keep the metal contacts on top of the battery clean.
● Battery usage by children should be supervised.
Charging
In order to avoid damage, charge the battery only in
●
temperatures that range from 32° F to 113° F (0° C
to 45° C).
● Don’t use the battery charger in direct sunlight or in
high humidity areas, such as the bathroom.
● The battery may need recharging if it has not been
used for a long period of time.
● It’s best to replace the battery when it no longer
provides acceptable performance. It can be
recharged hundreds of times before it needs
replacing.
10 Important Safety Information
Storing
Don’t store the battery in high temperature areas for
●
long periods of time. It’s best to follow these storage
rules:
▪ Less than one month:
-4° F to 140° F (-20° C to 60° C)
▪ More than one month:
-4° F to 113° F (-20° C to 45° C)
Disposal of Lithium Ion (Li-Ion) Batteries
Promptly dispose of used batteries in accordance
●
with local regulations.
● Never dispose of the battery by incineration.
● Do not handle a damaged or leaking Li-Ion battery
as you can be burned.
● For safe disposal options of your Li-Ion batteries,
contact your nearest Sprint authorized service
center.
Special Note: Be sure to dispose of your battery
properly. In some areas, the disposal of batteries in
household or business trash may be prohibited.
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
Important Safety Information 11
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
To maintain compliance with FCC RF exposure
guidelines, if you wear a handset on your body, use a
Sprint-supplied or Sprint-approved carrying case,
holster or other body-worn accessory. If you do not
use a body-worn accessory, ensure the antennas are
0.591 inch (1.5 centimeters) from your body
at least
when transmitting. Use of non-Sprint-approved
accessories may violate FCC RF exposure guidelines.
Other accessories used with this device for body-worn
operations must not contain any metallic components
and must provide at least
centimeters
antennas and the user’s body.

Specific 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 handset.
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
12 Important Safety Information
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 DuraMax are:
Cellular CDMA mode (Part 22):
Head: 0.41 W/kg; Body-worn: 1.29 W/kg
PCS mode (Part 24):
Head: 0.69 W/kg; Body-worn: 0.88 W/kg
BC10 CDMA mode (Part 90):
Head: 0.40 W/kg; Body-worn: 1.13 W/kg
