Instructions for Use
Clinical Benefits
Nonin pulse oximeters allow for the management of patients' medical condi-
tions by providing fast, accurate, real-time, noninvasive oxygen measurement in
order to meet patients' medical needs.
To use the Onyx
please follow the simple instructions below.
1. Insert two AAA batteries. Follow the polarity markings (+ and -) as illustrated in the figure below.
A
2. Insert patient's finger, nail side up, into the 9550 until the fingertip touches the built-in stop
guide. Ensure the finger is lying flat and is centered within the device.
3. The device detects the inserted finger and automatically illuminates the display. The display
changes colors to alert you of changes in pulse quality that may affect the readings:
• Green indicates a good pulse signal
• Yellow indicates a marginal pulse signal
• Red indicates an inadequate pulse signal
If the 9550 does not turn on or if it shuts off unexpectedly:
• Remove the finger and wait a few seconds before reinserting.
• Verify batteries are correctly inserted.
• If it still does not turn on, the batteries are depleted and must be replaced.
