(6) Do not touch, push or rub the exposed polarizes with glass, tweezers or anything
harder than HB pencil lead. And please do not rub with dust clothes with chemical
treatment.
Do not touch the surface of polarizer for bare hand or greasy cloth.(Some cosmetics
are detrimental to the polarizer.)
(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other
soft materials like chamois soaks with petroleum benzene. Normal-hexane is
recommended for cleaning the adhesives used to attach front / rear polarizers. Do not
use acetone, toluene and alcohol because they cause chemical damage to the
polarizer.
(8) Wipe off saliva or water drops as soon as possible. Their long time contact with
polarizer causes deformations and color fading.
(9) Do not open the case because inside circuits do not have sufficient strength.
9-2. OPERATING PRECAUTIONS
(1) The spike noise causes the mis-operation of circuits. It should be lower than following
voltage : V=±200mV(Over and under shoot voltage)
(2) Response time depends on the temperature. (In lower temperature, it becomes
longer.)
(3) Brightness depends on the temperature. (In lower temperature, it becomes
lower.)And in lower temperature, response time (required time that brightness is
stable after turned on) becomes longer.
(4) Be careful for condensation at sudden temperature change. Condensation makes
damage to polarizer or electrical contacted parts. And after fading condensation,
smear or spot will occur.
(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(6) Module has high frequency circuits. System manufacturers shall do sufficient
suppression to the electromagnetic interference. Grounding and shielding methods
may be important to minimize the interference.
