Most people like put the mp4 in their pocker or bag when they using it,it is inevitable bump anywhere,such as:in your bag,it is easily be scratches by key or other belongings,and it also will be vibration or impact your mp4 when you running.Also do not touch the screen directly by your hand in the process,you'd better to find soft cloth to wipe,absolutely necessary to allocation a protective casing or silica gel sleeve.And if you buy a screen protector,it is better.
Apart from the scratches,you also need to pay attention to the temperature,such as keep away the mp4 from the heating,the use of heat-bao,a number of high-temperature heating equipment,high temperatures is the fatal injury with screen,the screen will be displaye black by the high temperature,on the contrary,it also could not be used under low temperature,would also damage the screen!
At the same time,we should pay attention to the dust,generally,mp4 exposed in the air for a long time(especially on the ground or riding a bicycle,the dust easily into an mp4 from the small gap).
USB interface,headphone:
We are not recommend you use hard drive-based MP4 on the vehicle,because the vibration is easy to damage the hard drive,and it could also damage to the USB interface,and it is better rolled up headhope after you use it,not folded and wrapped so as not to break the headphone cable.
