After mounting, the contrast control should remain accessible for adjusting
the contrast of the display.
The whole area of the OP3 is covered with a protective foil. You can remove
the foil once the OP3 has been installed. OP3 functionality is also guaranteed
with the foil left on, however; further, the foil protects the device from
contamination.
