Customer has new biomedical group starting and they will check device before calling in for svc.At this time, the customer is just reporting failure.Per the field svc rep (fsr), the unit initially powerup to spec and ran all modes of operation with no indication of failure.The unit was powered down and up four or five times without fail.On the six or seventh time, the unit failed to go through its normal power up routine and the control panel would indicate no power and failure.After the power failure to the control panel, the fsr found that by resetting the printed circuit (pc) boards in the card rack, the unit would power on to normal state and all modes of operation worked correctly.The fsr proceeded to turn the unit off and on a half dozen times without further incident.The fsr performed preventive maintenance (pm), completed calibration and release test.The unit operated to mfr spec and was returned to clinical use.If add'l info becomes available on this complaint that would alter the facts and/or conclusion, a supplemental report will be failed accordingly.
