As your mobile phone can produce electromagnetic field, do not place it near magnetic items 
such as computer disks. 
 
Using the phone near electrical appliances such as TV, telephone, radio and personal 
computer can cause interference. 
 
Do not expose your mobile phone to direct sunlight or store it in hot areas. High temperatures 
can shorten the life of electronic devices. 
  Keep your phone dry. Any liquid may damage your phone. 
 
Do not drop, knock or harshly treat the phone. Rough handling can break internal circuit 
boards.

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

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 two-way radio is prohibited. 
Aircraft Safety 
 
Please turn off your mobile phone before the airplane 
takes off. In order to protect airplane’s 
communication system from interference, it is forbidden to use mobile phone in flight. Safety

plane is on the ground. 
 
If the mobile phone has the function of automatic timing power-on, please check your alarm 
setting to make sure that your phone will not be automatically turned on during flight.
