Installing Batteries
Two 1.5 volt AAA-size batteries power the Onyx
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
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
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
®
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
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
provides the correct pressure; additional pressure may cause inaccurate readings.
1. Insert the patient's finger, nail side up, into the Onyx
2. Make sure the finger is lying flat (not on its side) and is centered within the device. For best results, keep the Onyx
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

the startup sequence, the Onyx
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
removed. The last measured SpO
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.

Cleaning the Inner Surfaces of the Onyx
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.
