When the NPB-195 is turned on it will perform a POST (Power-On Self Test).
During POST the following sequence should occur:
• All indicator lights illuminate
• All pixels in the LCD display illuminate
• The backlight turns on and the Nellcor Puritan Bennett logo and software
version are displayed
Upon successful completion of POST, the NPB-195 sounds a 1-second tone
indicating that the monitor has passed the test.
If the start-up sequence is not completed as described above, do not use the
monitor.
The software version is often needed when calling Mallinckrodt's Technical
Services Department or your local Mallinckrodt representative for technical
assistance. Record the software version and have it available prior to requesting
technical assistance.
To perform test and troubleshooting procedures, and to understand the principles
of operation and circuit analysis sections of this manual, you must know how to
operate the monitor. Refer to the NPB-195 operator's manual. To understand
the various Nellcor sensors that work with the monitor, refer to the individual
sensor's directions for use.
