Electronic Devices
Your wireless telephone is a radio transmitter and receiver.
When the power is on, the phone receives and sends out RF
energy. Most modern electronic equipment, such as
equipment in hospitals and cars, contains an RF signal shield.
RF energy may affect some inadequately shielded electronic
equipment.
Turn off your phone in health care facilities, and always
request permission before using the phone near medical
equipment.
Consult the manufacturer of any personal medical devices,
such as pacemakers and hearing aids, to determine if they are
shielded adequately from external RF signals.
Note if there are any regulations posted in the area regarding
the operation of wireless phones, and learn where you can
use them safely within the facility.
Aircraft
Turn off your phone before boarding any aircraft. The Federal
Aviation Administration (FAA) requires that you have prior
permission from the crew to use your phone while the plane
is on the ground. FCC regulations prohibit using your phone
while the plane is in the air. Do not use your phone at any
time while traveling on board a plane.
Blasting Areas
Construction crews often use remote-control RF devices to
set off explosives. To avoid interfering with blasting
operations, turn off your phone when you are in a blasting
area or in any area with signs posted that read “Turn off two-
way radio.”
