Safety Environmental Instruction
z Avoid the dusty, humidity and temperature extremes. Do not place the product in any
area where it may become wet.
z 0 to 60 centigrade is the suitable temperature. (The figure comes from the request of the
main chipset)
z Generally speaking, dramatic changes in temperature may lead to contact malfunction
and crackles due to constant thermal expansion and contraction from the welding spots’
that connect components and PCB. Computer should go through an adaptive phase
before it boots when it is moved from a cold environment to a warmer one to avoid
condensation phenomenon. These water drops attached on PCB or the surface of the
components can bring about phenomena as minor as computer instability resulted from
corrosion and oxidation from components and PCB or as major as short circuit that can
burn the components. Suggest starting the computer until the temperature goes up.
z The increasing temperature of the capacitor may decrease the life of computer. Using the
close case may decrease the life of other device because the higher temperature in the
inner of the case.
z Attention to the heat sink when you over-clocking. The higher temperature may decrease
the life of the device and burned the capacitor.
