5. should adopt radiation structure to satisfy the temperature specification Acetic acid type and chlorine type materials for the cover case are not desirable because the former generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break by electro chemical reaction Do not touch push or rub the exposed polarizers with glass tweezers or anything harder than HB pencil lead Never rub with dust clothes with chemical treatment Do not touch the surface of polarizer for bare hand or greasy cloth Some cosmetics deteriorate the polarizer When the surface becomes dusty please wipe gently with absorbent cotton or other soft materials like chamois soaks with petroleum benzine 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 Wipe off saliva or water drops as soon as possible Their long time contact with polarizer Operating The spike noise causes the mis operation of circuits lt should be within the 200mV level Over and under shoot voltage Response time depends on the temperature In lower temperature it becomes longer 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 Be careful for condensation at sud
