(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.
