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 and/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 and/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.
Tip: Purchase an optional hands-free accessory at your local Sprint
Store, or call the Sprint PCS Accessory Hotline
SM at 1-800-974-
2221 or by dialing #222 on your phone.
