Installed)
The purpose of this test is for factory testing only. This test is not intended for field use.
7.5.11 SpO2 Diagnostics (Masimo SpO
2
Installed)
When this diagnostic is selected, the service menu will be replaced by a textual display of all
SpO2 errors recorded by the monitor. All errors will be automatically printed out on the
recorder as they are displayed on the screen, provided the unit is equipped with a recorder.
The DOWN ARROW key causes the display to clear, and the next page of messages to be
displayed. Continue to press the DOWN ARROW key unitl the message “Journal Empty” is
displayed.
NOTE: There is no buffering of the error journal messages,
therefore once an error message is displayed, it will be lost
if the DOWN ARROW or END key is depressed.
The Masimo Diagnostic Journal is not intended for interpretation in the field. There are
hundreds of different messages which could be recorded, and the messages vary with
software revision. Also, not all recorded messages indicate an error. If you suspect a problem
with the unit, the Masimo Diagnostic Journal should be printed out to the recorder (if
installed) and forwarded to a Datascope Service Representative or Datascope Technical
Support department.
