Operational Performance
Table 9 lists symptoms of problems relating to operational performance (no
error codes displayed) and recommended actions. If the action requires
replacement of a PCB or module, refer to
An alarm condition
exists but no alarm
(audible or visual) is
indicated.
Replace the Front Panel PCB. Refer to
Table 8: Display/Alarms Problems (Continued)

Recommended Action
Table 9: Operational Performance Problems
Symptom
Recommended Action
The
Pulse Amplitude
indicator seems to
indicate a pulse, but the
digital displays show
zeroes.
The sensor may be damaged; replace it.
Replace the Front Panel PCB. Refer to
SpO
2
or pulse values
change rapidly;
Pulse
Amplitude
indicator is
erratic.
The sensor may be damp or may have been reused too
many times. Replace it.
• An electrosurgical unit (ESU) may be
interfering with performance:
• Move the N-560 and its cables and sensors as
far from the ESU as possible.
• Plug the N-560 power supply and the ESU
into different AC circuits.
• Move the ESU ground pad as close to the
surgical site as possible and as far away from
the sensor as possible.
• Verify the performance with the procedures
detailed in
• Replace the Front Panel PCB. Refer to
