176 Section 4A: Important Safety Information

Maintaining Safe Use ofand 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.

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.
Note: Always turn off the phone in healthcare facilities, and request permission before
using the phone near medical equipment.
