9.0 TROUBLESHOOTING
9.1 Electrical System
In the advent of a table malfunction, the first item to investigate is the input power. Be
certain that the power cord is plugged into a live electrical outlet and the power switch is
on. This is evidenced by an illuminated on/off switch.
If none of the functions are operating, the floor lock may not be completely deployed.
Press the FLOOR LOCK button until the green LOCKED WHEN LIT indicator is
illuminated.

WARNING:
If the floor lock is deployed as evidenced by visual inspection, all four floor lock
feet should be in contact with the floor. Table should not move whether or not
the green indicator is illuminated, and the up/down, lateral roll or trendelenburg
functions do not operate. The floor lock override button can be used to
temporarily bypass the interlock on the floor lock system. This button is located
on the underside of the sheet metal housing at the FLOOR LOCK buttons (see
figure 10). Press and hold this button while simultaneously operating the desired
function on the hand pendant. Once released, no functions will be operable and
this button must be pressed again if subsequent table movement is required.
This override button only powers the height, trendelenburg and lateral roll
functions on the hand pendant and is intended for emergency situations only. If
it becomes necessary to use this feature, call Mizuho OSI Customer Resource
Group immediately to arrange for table service.
