Troubleshooting

Data Port
Table 9 on page 48 lists symptoms of problems relating to the data port and
recommended actions. If the action requires replacement of the User Interface
PCB, refer to
Disassembly Guide
on page 51.
Error Codes
An error code is displayed when the N-595 detects a non-correctable failure.
Cycling the power clears these errors. When an error code occurs, the unit
stops monitoring, sounds a low-priority alarm that cannot be silenced, clears
patient data from the display, and displays an error code. Table 10 on page 49
provides a complete list of error codes and possible solutions or problem
identification.
When an error code (other than the ones listed in Table 10 on page 49) is
displayed, turn the instrument off and back on again. If the error code
reappears, record it and notify Nellcor Technical Services Department.

Symptom
Recommended Action
No printout is being
received.
•
Confirm that printer is working through an
alternate means.
•
The monitor's baud rate does not match the
printer. Change the baud rate of the monitor
following instructions in
Configuring the Data
Port
on page 89.
•
If the condition still persists, replace the User
Interface PCB. See
User Interface PCB Removal/
Replacement
The RS-232 nurse call
is not working.
•
Verify that connections are made between pins 5
(GND) and 11 (nurse call) of the data port
(Figure 20 on page 98).
•
Verify that the output voltage between ground pin
5 and pin 11 is -5 to -12 VDC (no alarm) and +5
to +12 VDC (during alarm) (Figure 20 on
page 98).
•
If the condition still persists, replace the User
Interface PCB. See
User Interface PCB Removal/
Replacement
on page 64.
