Note:
• Since the sensors respond only when the cover is closed, be sure to close the cover
before re-installing any items.
• The sensors tests, especially the OPC test, require time to respond on the LCD panel.
Operate a sensor in one sense for at least 20 seconds before restoring it to the
original condition for reliable operation of these tests.
