Important Safety Information
Maintaining Safe Use of and Access to Your Device
Do Not Rely on Your Device 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 Device While Driving

Talking on your device while driving (or operating the device
without a hands-free device) is prohibited in some jurisdictions.
Laws vary as to specific restrictions. Remember that safety
always comes first.

Following Safety Guidelines

To operate your device safely and efficiently, always follow any
special regulations in a given area. Turn your device off in
areas where use is forbidden or when it may cause
interference or danger.

Using Your Device 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.

Turning Off Your Device Before Flying

Turn off your device 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 device while
the plane is on the ground. To prevent any risk of interference,
FCC regulations prohibit using your device while the plane is in
the air.
Tip: Purchase an optional hands-free accessory at your local
Sprint Store, or call Sprint at 1-866-866-7509. You can also
dial # 2 2 2 on your device.
Note: Always turn off the device in healthcare facilities, and request
permission before using the device near medical equipment.
