Powering the Oximeter
Power Prerequisites
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.
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 completes, verify that a single one-second tone sounds.
Before using the oximeter in a clinical setting, verify the oximeter is safe and working
properly. Verify proper working condition at each power up by following the
procedure below.
Power-on Self -Test (POST)
At power on, the OxiMax N-600x pulse oximeter performs a power-on self-test
(POST), which tests the oximeter circuitry and functions, then proceeds to the
default display. With a sensor cable and an OxiMax pulse oximetry sensor attached,
the unit is ready to register and record patient trend data.
Note:
Physiological conditions, medical procedures, or external agents such as dysfunctional
hemoglobin, arterial dyes, low perfusion, dark pigment, and externally applied coloring
agents such as nail polish, dye, or pigmented cream may interfere with the oximeter’s ability
to detect and display measurements.
To power up the oximeter
WARNING
If you do not hear the power-on self-test (POST) pass tone, do not use the oximeter.
Instead, contact Nellcor’s Technical Service or your local Nellcor representative.
WARNING
Ensure the speaker is clear of any obstructions. 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 warning sounds cannot be heard.
1. Turn on the oximeter by pressing the ON/STANDBY key.
2. Ensure all of the front panel indicators illuminate for about two seconds.
3. Observe the LCD screen for the POST splash screen, which displays for approximately five
seconds.
