Other Medical Devices
If you use any other personal medical device, consult the manufacturer
of your device to determine if they are adequately shielded from
external RF energy. Your physician may be able to assist you in
obtaining this information.
Turn your phone Off in health care facilities when any regulations
posted in these areas instruct you to do so. Hospitals or health care
facilities may be using equipment that could be sensitive to external RF
energy.
TTY Access
A TTY (also known as TDD or Text Telephone) is a
telecommunications device that allows people who are deaf or hard of
hearing, or who have speech or language disabilities, to communicate
by telephone. It is possible to use your phone with a TTY. For more
information, contact the manufacturer of the TTY device.
Vehicles
RF signals may affect improperly installed or inadequately shielded
electronic systems in motor vehicles. Check with the manufacturer or
its representative regarding your vehicle. You should also consult the
manufacturer of any equipment that has been added to your vehicle.
Posted Facilities
Turn your phone Off in any facility where posted notices so require.
Aircraft
FCC regulations prohibit using your phone while in the air. Switch Off
your phone before boarding an aircraft.
