General Troubleshooting Guidelines

This procedure does not cover all possible problems. The intent of troubleshooting is to
provide quick isolation and remedy of malfunctions and to return the instrument promptly
to safe patient care. A logical approach will quickly identify the problem and suggest cost-
effective solutions.

Troubleshooting Tips

1. Isolate the cause of the problem to be either clinical, instrument, or external. If a

Exchange Program

A comprehensive circuit board and electro-mechanical module exchange program is
available. The exchange circuits and modules are warranted, factory pre-tested and
calibrated. Final calibration of the exchange item is strongly suggested to match the new
part to the host system. See section 4.4 for details concerning the exchange program.

clinical cause is suspected, take the physiological measurement by a manual method
or use an alternate measuring device. Check the physiological value against the
instrument specifications; if it exceeds specification, continue with manual or
alternate method.
If a problem with the instrument is suspected, first examine and / or replace patient
connected accessories. Check instrument set-up / configuration. If all set-ups are OK,
replace instrument with similar device.
If the environment is suspected, observe if the malfunction coincides with other
equipment cycling (especially high-power motors, RF generators, etc.). Replace
problem instrument with an identical substitute. Place the problem instrument in a
low-disturbance environment. If the problem persists in the low-disturbance
environment, the instrument performance may be suspect. If the substitute instrument
exhibits similar poor performance in the original environment, the environmental
causes must be eliminated.

performance standards of the equipment suggested.

or methyl alcohol and a stiff hair brush. This will remove residual solder flux, making
the repaired area more visible for an inspection and returning the instrument to its
original, neat appearance. Removal of the flux will also facilitate making electrical
measurements in the affected area as the flux itself is not conductive.
