Troubleshooting
N-560 Operator’s Manual 77
1. There is no response to the
Power On/Off
button.
• If the N-560 is operating on AC power, the fuse may be blown.
Notify service personnel to check and, if necessary, replace the
fuse.
• If the N-560 is on battery power, the battery fuse may require
replacement, the battery may be missing, or the battery may be
discharged. Charge the battery or notify service personnel to
replace the battery or the battery fuse, as required.
2. One or more display segments or indicators do not light during
the power-on self-test.
• Do not use the N - 560; contact qualified service personnel or your
local Nellcor representative.
3. The N-560 does not sound a tone indicating successful completion
of the Power-On Self-Test (POST).
• The N-560 has failed the power - on self - test. Do not use the
N-560. This tone not only indicates the successful completion of
POST, but it confirms that the audible alarm is functional.
Contact qualified service personnel or your local Nellcor
representative.
4. The Pulse Search indicator is lit for more than 10 seconds while
the sensor is connected to the patient.
• Check the sensor directions for use to determine if an appropriate
sensor is being used and if it is applied properly. Check sensor
and sensor cable connections. Test the sensor on someone else.
Try another sensor or sensor cable.
