INSTALLATION NOTE

To protect the front polarizer from accidental damage it is highly recommended that the LCD be mounted
behind a clear glass or polycarbonate window material.  It is also recommended that an air gap of at least .030"
to .050" minimum be provided between the window material and the surface of the LCD to prevent the transfer
of static charges to the front surface of the LCD.  Supertwist LCD’s may activate un–driven elements in
response to a surface static charge on the front polarizer.  It may take several minutes for such a surface static
charge to dissipate.
