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.”
