2. After all visible contamination is removed, use a second germicidal wipe to
thoroughly wet the surfaces of the device and accessories. Allow to remain
wet for 4 minutes. Use additional wipes if needed to assure surfaces are
wetted continuously for 4 minutes.
3. Allow device to air dry.
4. Visually inspect each component for visible contamination.
CAUTION: Excessive rubbing of labels may cause them to become illegible.
DO NOT spray cleaning solutions directly onto the monitor, sensor or buzzer opening.
DO NOT immerse the MaxO
2
ME or sensor into liquid decontamination agents.
DO NOT use strong solvent cleaners.
DO NOT allow cleaning liquids to contact the face of the sensor as this may impair the
readings of the sensor.
DO NOT attempt to sterilize the MaxO
2
ME with steam, ethylene oxide or irradiation.
6.2 Alarm Testing
Periodic testing of alarms should be performed on a yearly basis.
To check the low alarm, adjust the low alarm setting to 23% or higher and expose the sensor
to room air (20.9%). The low alarm LED should flash with the alarm sound.
To check the high alarm, adjust the low alarm setting to 17% or lower and the high alarm setting
to 18% and expose the sensor to room air (20.9%). The high alarm LED should flash with the
alarm sound. If one or both alarms malfunction, contact Maxtec Certified Service Technician.
6.3 Replacing Sensor Cable
After extended use or abuse to the sensor cable, the cable may begin to wear and loose
its ability to properly retract.
The cable can be removed and replaced by disconnecting the threaded locking shroud
at the sensor and monitor ends of the cable. Use only the Maxtec approved cable
called out in Section 9.0 of the Spare Parts List.
NOTE: Ensure the cable locking shroud is fully threaded on the sensor and the monitor.
