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 specific restrictions. Remember that safety
always comes first.
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 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:
For the best care of your phone, only Sprint-authorized
personnel should service your phone and accessories.
Failure to do so may be dangerous and void your
warranty.
Note: 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 phone.
Note: Always turn off the phone in healthcare facilities, and
request permission before using the phone near
medical equipment.
