5.5.6 Error Codes
When the N5500 detects an error condition, the monitor will attempt to show an error
code on the display screen.
If such an error occurs during monitoring operation, the monitor will sound a low-
priority alarm. Audible alarm can be terminated by pressing Alarm silence/suspend
switch, but it depends on error codes and conditions.
Table 19 provides a complete list of error codes and problem identification.
If an error code occurs, take the following actions:
1. Turn monitor off, then on again.
Note: If error code still appears, take monitor out of service and contact Nellcor
Technical Services or your local Nellcor representative for advice on remedial
action.
