1.1 Safety Instructions

By complying with the following safety principles, you can ensure personal safety and protect the

products and working environment from potential damage:

Driving safety first! When you drive, do not use handheld mobile terminal device

unless it has a hands-free function. Please stop the car before calling!

Please turn off the mobile terminal device before boarding. The wireless function

of mobile terminal shall not be turned on in the aircraft to prevent interference

with the aircraft communication system. Ignoring this reminder may affect flying

safety or even violate the law.

In hospitals or health care facilities, pay attention to whether there are restrictions

on the use of mobile terminal device. RF interference will cause medical

equipment to be abnormal, so mobile terminal device may need to be turned off.

Mobile terminal device cannot always be effectively connected, for example, if

the mobile device has no expense or the SIM is invalid. When you encounter the

above situations in an emergency, please make an emergency call, meanwhile,

ensure that your device is turned on and in an area with sufficient signal strength.

Your mobile terminal device will receive and transmit radio frequency signals

when it is turned on. There will be radio frequency interference when it is close to

TV, radio, computer or other electronic equipment.

Please keep mobile device away from inflammable gases. Please turn off the

mobile terminal device when you are near a fueling station, oil depot, chemical

plant or explosion site. There will be potential safety hazards when operating

electronic equipment in any place with potential explosion hazard.
