Replace batteries. A medium priority alarm will sound every 25 seconds until the
•
batteries are replaced or become too dead to sound the alarm. Refer to section 2.1.1,
Battery Installation.
PROBLEM: E05: Sensor voltage is too high to perform a valid calibration.
POTENTIAL CAUSES AND SOLUTIONS:
Manually attempt a new calibration. Refer to section 2.8, Calibration Procedures.
•
If unit repeats this error more than three times, contact Maxtec's Customer Service
•
Department for possible sensor replacement.
PROBLEM: E06: Non-compatible oxygen sensor.
POTENTIAL CAUSES AND SOLUTIONS:
Disconnect the sensor and reconnect, making sure the male plug is fully inserted into
•
the receptacle. The analyzer should now perform a new calibration with the error
cleared.
If the error still persists, remove the batteries, wait 30 seconds, then reinstall, to
•
perform a factory reset and diagnostic on the analyzer. The analyzer should again
perform a new calibration with the error cleared.
Contact Maxtec Customer Service Department if the error code cannot be cleared.
•
PROBLEM: E07: Sensor signal is not stable enough to perform a valid calibration.
POTENTIAL CAUSES AND SOLUTIONS:
Wait for displayed oxygen reading to stabilize when calibrating the device at 100%
•
oxygen.
Wait for unit to reach thermal equilibrium. Please note that this can take up to one
•
half hour, if the device is stored in temperatures outside the specified operating
temperature range.
PROBLEM: E08: Battery voltage is too low to perform a valid calibration.
POTENTIAL CAUSES AND SOLUTIONS:
Replace batteries. Refer to section 2.1.1, Battery Installation.
•
NOTE: Use only the Maxtec-approved Max-550E sensor described in section 10.0, Spare Parts
and Accessories. The Max550E sensor is equipped with an authentication chip to ensure the
monitor is used with an approved sensor.
NOTE: The operator must be facing the device and positioned within 4 meters to distinguish
the visual alarm indicators. Audible alarms can be distinguished as long as the operator is in
the same room, and the ambient noise level is typical for a clinical setting.
5.0 CLEANING AND DISINFECTING
The external surfaces of the device, and its accessories, can be cleaned and disinfected using
the process detailed below. Under normal use conditions, the sensing surfaces of the sensor
should not become contaminated. If you suspect that the sensing face of the sensor or internal
surfaces of the flow diverter have become contaminated, these items should be discarded and
replaced. Store the device in a clean, dry location when not in use.
To clean and disinfect:
1. Ensure battery drawer is closed and sensor/diverter are inserted into their port.
2. Using disposable Super Sani-Cloth germicidal wipes (medical-grade 2-in-1 cleaning/
disinfecting wipes), remove all visible contamination from the external surfaces of the
device and its accessories. Be sure to closely inspect and remove contamination from
seams and recesses on the device that may trap contaminants. Wipe with clean paper
towel to remove debris and bioburden.
3. 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.
4. Allow device to air dry completely.
5. Visually inspect the device for visible contamination. Repeat cleaning/disinfection
process if visible soil remains.
DO NOT allow the liquid or spray to penetrate the device.

DO NOT spray cleaning solution directly onto the sensor port, bleed muffler or buzzer
openings.
Be sure to thoroughly clean and disinfect the areas depicted in the images below. These
regions are contacted during normal use and may contribute to cross-contamination if not
disinfected properly.
CAUTION: Excessive rubbing of labels may cause them to become illegible.
DO NOT immerse the device 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 device with steam, ethylene oxide or irradiation.
6.0 SERVICE AND MAINTENANCE
6.1 Maintenance
Maxtec recommends that the Performance Check listed in section 3.0 is performed at least
once a year.
When using the MaxBlend 2 with a medical-grade compressed air source, it is recommended
that an air inlet watertrap/filter be attached to the air inlet of the MaxBlend 2 prior to use.
Contaminants from hospital air lines may compromise the function of the MaxBlend 2.
Maxtec recommends that the MaxBlend 2 be overhauled and serviced at a minimum of every
three years.
Repair of this equipment must be performed by a Maxtec Certified Service Technician experi-
enced in the repair of this device.
6.2 Replacing O2 Sensor
The oxygen sensor is designed to operate for two years under normal use conditions. The
oxygen sensor should be replaced whenever any of the problems listed in section 4.0,
Troubleshooting dictate the need to do so.
To replace the O2 sensor:
1. Remove the sensor from the sensor monitor port.
2. Remove the sensor from the sensor cable.
3. Install a new O2 sensor with flow diverter and attach to the sensor cable.
4. Calibrate the sensor following the instructions for calibration listed in section 2.8.
6.3 Monitor Alarm Testing
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 a
Maxtec Certified Service Technician.
