10 USE PRECAUTIONS
10-1 Handling precautions
1) The polarizing plate may break easily so be careful when handling it. Do not
touch, press or rub it with a hard-material tool like tweezers.
2) Do not touch the polarizing plate surface with bare hands so as not to make it
dirty. If the surface or other related part of the polarizing plate is dirty, soak a
soft cotton cloth or chamois leather in benzine and wipe off with it. Do not use
chemical liquids such as acetone, toluene and isopropyl alcohol. Failure to do
so may bring chemical reaction phenomena and deteriorations.
3) Remove any spit or water immediately. If it is left for hours, the suffered part
may deform or decolorize.
4) If the LCD element breaks and any LC stuff leaks, do not suck or lick it. Also if
LC stuff is stuck on your skin or clothing, wash thoroughly with soap and water
immediately.
10-2 Installing precautions
1) The PCB has many ICs that may be damaged easily by static electricity. To
prevent breaking by static electricity from the human body and clothing, earth
the human body properly using the high resistance and discharge static
electricity during the operation. In this case, however, the resistance value
should be approx. 1MΩ and the resistance should be placed near the human
body rather than the ground surface. When the indoor space is dry, static
electricity may occur easily so be careful. We recommend the indoor space
should be kept with humidity of 60% or more. When a soldering iron or other
similar tool is used for assembly, be sure to earth it.
2) When installing the module and ICs, do not bend or twist them. Failure to do so
may crack LC element and cause circuit failure.
3) To protect LC element, especially polarizing plate, use a transparent protective
plate (e.g., acrylic plate, glass etc) for the product case.
4) Do not use an adhesive like a both-side adhesive tape to make LCD surface
(polarizing plate) and product case stick together. Failure to do so may cause
the polarizing plate to peel off.
