Using Your Phone Near Other Electronic Devices; Turn Off Your Phone Before Flying - Sprint QCP-196 User Manual

Using your phone near other electronic devices.

Most modern electronic equipment is shielded from radio
frequency (RF) signals. However, RF signals from PCS telephones
may affect inadequately shielded electronic equipment.
RF signals may affect improperly installed or inadequately
shielded electronic operating and entertainment systems in motor
vehicles. Check with the manufacturer or its representative to
determine if these systems are adequately shielded from external
RF signals. You should 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. Turn off the phone
in healthcare facilities and request permission before using the
phone near medical equipment.

Turn off your phone before flying.

You should turn off your phone before boarding any aircraft. To
prevent possible interference with aircraft systems, 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.
