HANDLING INSTRUCTIONS
Mounting Module
This module designed mounted equipment using mounting tabs four corners module. When installing module, handle carefully avoid undue stress, such twising bending. module should affixed metal part equipment. Contact with resin region cause damage.
Working Procedures
Direct wind heated ionized discharging blower somewhat downward ensure that module blown sufficiently. Keep distance between module blower within (see Figure 12a). Attach adhesive tape laminater part near discharging blower protect polarizer against flaws (see Figure 12b). Peel laminator, pulling adhesive tape slowly your side taking five more seconds. important that takes more than five seconds. After peeling laminator, pass module next work process immediately without getting module dusty.
Precautions Mounting
polarizer, which made soft material susceptible flaws, must handled carefully. Protective film laminator applied surface protect against scratches dirt. Peel laminator just before using avoid static electricity.

LQ4RE01/LQ4RE02 Methods removing dust from polarizer: Blow dust with blower which static electricity preventive measures have been taken. ionized (Hugle Electronics Co.) recommended. Since polarizer easily damaged, avoid wiping this unavoidable, wipe carefully with lens cleaning cloth, breathing `Belleseime' (Kanebo, Ltd.) desirable. When metal parts module (shielding rear case) soiled, wipe them with soft, cloth. stubborn dirt, wipe part, breathing gently Wipe liquid immediately since cause color changes staining. TFT-LCD module made glass plates. care when handling avoid breakage. This unit contains CMOS LSIs which sensitive electrostatic charges. care protect unit from electrostatic discharges.
TFT-LCD Modules panel breaks, liquid crystal escape from panel. Since liquid crystal harmful, into eyes mouth. When liquid crystal sticks hands, feet clothes, wash immediately with soap. Static image should displayed more than five minutes order prevent occurrence residual image. recommended that display pattern changed periodically operation display ON/OFF should turned intermittently. VCDC must adjusted according `Adjusting Method Optimum Common Electrode Bias Voltage.' adjustment causes deterioration display quality. Observe other precautionary requirements handling general electronic components.
