Using the Monitor
30
Note: Physiological conditions, medical procedures, or external
agents that may interfere with the monitor's ability to detect
and display measurements, include dysfunctional hemoglobin,
arterial dyes, low perfusion, dark pigment, and externally
applied coloring agents such as nail polish, dye, or pigmented
cream.
Note: The monitor automatically starts the Power-On Self-Test
(POST), which tests the monitor circuitry and functions.
Caution: During POST (immediately after power-up), confirm
that all indicators light, all display segments turn on, and the
pulse oximeter speaker sounds a one-second tone.
1. Turn on the N-595 by pressing the ON/STANDBY button.
2. Ensure that all of the front panel indicators illuminate.
3. Once the display test portion of POST is complete, the N-595
software version is displayed for approximately 5 seconds.
Note: The software version shown above is only a sample. Check
your monitor for the software version installed.
Software version numbers are often needed when calling Nellcor's
Technical Services Department or your local Nellcor representative
for technical assistance. Write down the software version number and
have it available prior to requesting technical assistance.
