Installing Batteries
Two 1.5 volt AAA-size batteries power the Onyx
®
II for about 2,500 spot checks or 21 hours of operation. NONIN®
recommends using alkaline batteries (included with each new Onyx II). When batteries are low, the numeric displays flash
once per second. Remove batteries if the device will be stored for more than 30 days. Replace low batteries as soon as
possible, using the instructions below.
Note: Rechargeable batteries may be used; however, they require more frequent replacement.
1. Hold the Onyx
®
II as shown at left, pressing upward and then pulling outward slightly with the thumb to release the
device’s battery tray.
2. Remove the battery tray and the old batteries, disposing of the batteries properly.
3. Insert two new 1.5 volt AAA-size batteries. Follow the polarity markings (+ and -) as illustrated.
Proper positioning of the
batteries is essential for operation.
4. Carefully guide the battery tray back onto the Onyx
®
II, pressing downward and pushing inward slightly to re-secure the
battery tray.
Do not force it into place; it fits only when properly positioned.
5. Insert your finger into the device to verify operation.
Activating the Onyx
®
II and Verifying Operation
The Onyx
®
II contains numeric LEDs that display oxygen saturation and pulse rate. A tricolor LED display provides a visual
indication of the pulse signal quality, while blinking at the corresponding pulse rate. This display changes colors to alert you
to changes in pulse quality that may affect the readings:
green
indicates a good pulse signal,
yellow
indicates a marginal pulse
signal, and
red
indicates an inadequate pulse signal.
Activate the Onyx
®
II by inserting the patient’s finger into the unit. The Onyx
®
II detects the inserted finger and automatically
illuminates the displays. Correct positioning of the light emitter and photodetector on the finger is critical for accurate
measurements. All emitted light must pass through the fingertip.
While on the finger, do not press the Onyx
®
II against any surface and do not squeeze or hold it together. The internal spring
provides the correct pressure; additional pressure may cause inaccurate readings.
1. Insert the patient’s finger, nail side up, into the Onyx
®
II until the fingertip touches the built-in stop guide.
2. Make sure the finger is lying flat (not on its side) and is centered within the device. For best results, keep the Onyx
®
II at
the patient’s heart or chest level.
3. If the device does not turn on, remove the finger and wait a few seconds before reinserting it.
When a finger is inserted, the Onyx
®
II performs a brief startup sequence. Verify that all LEDs illuminate during the startup
sequence. If any LED is not lit, do not use the Onyx
®
II; contact NONIN
®
Customer Support for repair or replacement. After
the startup sequence, the Onyx
®
II begins sensing the pulse (indicated by the blinking pulse quality display). Allow the device
to stabilize, observing about 4 seconds of continuous green-colored pulse quality before relying on the displayed values. It is
common for the displayed values to fluctuate slightly over a period of several seconds. If the pulse quality display blinks yellow
or red, try another finger.
A minus sign (-) appears in the left-most digit of the %SpO
2
display when the Onyx
®
II senses that the finger has been
removed. The last measured SpO
2
and pulse rate values freeze for 10 seconds, and then “OFF” will appear in the display
while the device turns off. The device will automatically shut off (to conserve battery life) approximately 10 seconds after the
finger is removed, or after a 2-minute period of inadequate pulse signals.
Using the Lanyard and Carrying Case
A lanyard and carrying case are provided for convenience. The Onyx
®
II will function with or without the lanyard.
•
If lanyard use is desired, thread the lanyard as shown below.
Onyx
®
II Care, Maintenance, and Cleaning
The advanced digital circuitry within the Onyx
®
II requires no calibration or periodic maintenance other than battery
replacement. Field repair of the Onyx
®
II circuitry is not possible. Do not attempt to open the Onyx
®
II case or repair the
electronics. Opening the case will damage the Onyx
®
II and void the warranty. Do not open the Onyx
®
II more than 90°, and
do not twist or pull on the device when cleaning.
Cleaning the Inner Surfaces of the Onyx
®
II
1. Wipe the surfaces with a soft cloth dampened with a mild detergent or isopropyl alcohol solution. If low-level disinfection
is required, a cloth dampened with 10% bleach / 90% water solution may also be used. Do not use undiluted bleach or
any cleaning solution other than those recommended here, as permanent damage could result.
2. Dry with a soft cloth, or allow to air dry.
!
Caution
Do not use caustic or abrasive cleaning agents.
3. Ensure that all surfaces are completely dry.
