Medical Devices; Interference In Cars - Zte Z557BL User Manual

Medical Devices

Please consult your doctor and the device manufacturer to
determine if operation of your phone may interfere with the
operation of your medical device.
Hospitals
Turn off your wireless device when requested to do so in
hospitals, clinics or health care facilities. These requests are
designed to prevent possible interference with sensitive medical
equipment.
Aircraft
Turn off your wireless device whenever you are instructed to do
so by airport or airline staff.
Consult the airline staff about the use of wireless devices
onboard the aircraft. If your device offers a 'flight mode', this must
be enabled prior to boarding an aircraft.

Interference in Cars

Please note that because of possible interference with electronic
equipment, some vehicle manufacturers forbid the use of mobile
phones in their vehicles unless a hands-free kit with an external
antenna is included in the installation.
