5.2 Preventative Maintenance
5.2.1 Visual Inspection
Inspect the monitor for obvious damage. The test is passed if the monitor has no obvious damage. Follow these
guidelines when inspecting the monitor:
Carefully inspect the enclosure, display, buttons, and knob for obvious damage.
Inspect the power cord and module accessories for obvious damage.
Inspect all external connections for loose connectors, bent pins or frayed cables.
Inspect all connectors on the monitor for loose connectors or bent pins.
Make sure that safety labels and data plates on the monitor are clearly legible.
