CAUTIONS:
•
Do not autoclave, pressure sterilize, or gas sterilize this oximeter.
•
Do not soak or immerse the monitor in any liquid.
•
Use the cleaning solution sparingly. Allow unit to air dry. Excessive
solution can flow into the monitor and cause damage to internal
components.
•
Do not touch, press, or rub the display panels with abrasive cleaning
compounds, instruments, brushes, rough-surface materials, or bring
them into contact with anything that could scratch the panel.
•
Do not use petroleum-based or acetone solutions, or other harsh
solvents, to clean the oximeter. These substances attack the
device’s materials and device failure can result.
