19. Notices for the use of phone
Your phone is a product of superior design and craftsmanship and should be treated
with care. The following suggestions can help you comply with the terms of repair kits, to
extend the life of mobile phone.
1) Keep the mobile phone, parts and components out of the reach of children.
2) Keep the phone dry. Rain, humidity and all types of liquids which contain minerals will
corrode electronic circuits.
3) Don’t touch the phone with wet hands when charging. Doing so will cause electric shock
or product damage.
4) Avoid subjecting the device to a high-temperature environment. Temperatures will
shorten the life of electronic devices, damage batteries, and warp or melt certain
plastics.
5) Avoid subjecting the device to an excessively low temperature environment. When the
temperature rises, the phone will produce water vapor that may damage the electronic
circuitry.
6) Avoid place the phone in dusty, dirty places, or the parts may be damaged.
7) Keep the phone away from lit cigarettes, open flames and other heat sources.
8) Do not open the device, as the phone will be damaged without specific knowledge of the
procedure.
9) Do not throw it from a height. Do not knock or shake the phone, as rough handling can
damage the internal circuit boards.
10) Do not paint the phone, because the paint will block headphones, microphones or other
removable parts and lead to a malfunction.
11) Use a clean, soft, dry cloth to clean the camera and the light-sensor lenses. Prohibit the
use of harmful chemicals and cleaning agents (such as cleaning fluids) to clean the
phone.
12) If the mobile phone, battery, charger or mobile phone accessories are defective, send to
the nearest qualified service center for inspection.
13) If necessary, the service center staff will assist you and arrange for phone repairs.
