Power-On Defaults And Alarm Limit Ranges - Nellcor OxiMax N-550B Service Manual

Power-On Defaults and Alarm Limit Ranges

N-550B
Note: The version above is only a sample. Check your N-550B for the
current version installed.
The version number is needed when calling Nellcor's Technical
Services Department, 1.800.635.5267, or your local Nellcor
representative for technical assistance. Write down the number and
have it available prior to requesting technical assistance.
6. If the N-550B detects an internal problem during the POST, an alarm tone
sounds and the N-550B displays an Error Code and corresponding
number. See Troubleshooting on page 43.
7. Upon successful completion of the POST, the N-550B sounds a
one-second tone indicating that the N-550B has passed the test.
WARNING: If you do not hear the POST pass tone, do not use the
N-550B.
WARNING: Ensure that the speaker is clear of any obstruction. Failure
to do so could result in an inaudible alarm tone.
Note: In addition to serving as the POST pass verification, the POST pass
tone also functions as an audible confirmation that the speaker is
performing properly. If the speaker does not function, the alarm
sounds cannot be heard.
See Figure 3 on page 9 for the location of the N-550B controls.
Note: When observing or changing default limits, a three-second time-out is
in effect. That is, if no action is taken within three seconds, the
N-550B automatically returns to the normal mode.
