Precautions for Electronic Devices
Some electronic devices are susceptible to
electromagnetic interference sent by mobile phone
if inadequately shielded, such as electronic system
of vehicles. Please consult the manufacturer of the
device before using the phone if necessary.
Safety and General Use in Vehicles
Safety airbag, brake, speed control system and oil
eject system shouldn't be affected by wireless
transmission. If you do meet problems above,
please contact your automobile provider. Do not
place your phone in the area over an airbag or in
the airbag deployment area. Airbags inflate with
great force. If a phone is placed in the airbag
deployment area and the airbag inflates, the
phone may be propelled with great force and
cause serious injury to occupants of the vehicle.
Please turn off your mobile phone at a refueling
point, and the same to the place where the use of
