Using the Monitor
Turning On the Monitor
Before using the monitor in a clinical setting, verify the monitor is
safe and working properly. Proper working condition is verified each
time the N-600x is turned on as described in the following procedure.
Caution: If any indicator or display element does not light when
the pulse oximeter is turned on, do not use the pulse oximeter.
Instead, contact qualified service personnel, your local Nellcor
representative, or Nellcor's Technical Services Department.
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 launches 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 sequence of three ascending
tones. After the POST process complete, verify that a single one-
second tone sounds.
1. Turn on the monitor by pressing the ON/STANDBY button.
2. Ensure all of the front panel indicators illuminate.
