Checking Connections
Check all signal wiring, power and ground connections within
the cabinet to verify their integrity. When checking connec-
tions, always turn a screw, nut or other fastening device in the
direction to tighten only. If the connection is loose, it will be
tightened. If the connection is tight, the tightening action will
verify that it is secure. There must not be any motion done to
loosen the connection.
NOTE: Power to the cabinet should be off while performing this pre-
ventive maintenance task.
Verify that all cable connections are secure.
