4 ERROR CODES
The UltraMax O2 has self diagnostic features built into the software to detect faulty readings
outside of normal operating ranges. The codes, descriptions and recommended actions are:
E01: Oxygen measurement out of range Hi ( ≥ 102.0% calculated by algorithm).
Recommended Action: Verify that the UltraMax O2 is being used in the correct mode (Concen-
trator or Calibration Verification mode). If error code repeats; perform a calibration verification
per section 2.3 of this manual. If error code repeats again; contact Maxtec Customer Service.
E02: Oxygen measurement out of range Low ( -2.0% calculated by algorithm).
Recommended Action: Verify that the UltraMax O2 is being used in the correct mode (Concen-
trator or Calibration Verification mode). If error code repeats; perform a calibration verification
per section 2.3 of this manual. If error code repeats again; contact Maxtec Customer Service.
E03: Device memory corrupt or missing.
Recommended Action: Return the UltraMax O2 to the manufacturer for factory repair.
E04: Signal reading not stable.
Recommended Action: Return the UltraMax O2 to the manufacturer for factory repair.
E05: Pressure measurement out of Range Hi ( ≥ 50 PSI).
Recommended Action: Check the pressure on a known gas source pressure. If error code repeats;
contact Maxtec Customer Service.
E06: Outside of operating temperature Hi ( ≥ 40° C).
Recommended action: The UltraMax O2 is too hot, cool the device closer to room temperature
before use.
E07: Outside of operating temperature Low ( 15° C).
Recommended action: The UltraMax O2 is too cold, warm the device closer to room temperature
before use.
E08: Device self check found error.
Recommended Action: Remove and replace the batteries. If error code repeats; return the
UtraMax O2 to the manufacturer for factory repair.
5 CHANGING THE BATTERIES
Batteries should be changed by service personnel. Use only brand name batteries. Replace with
two AA batteries and insert per orientation marked on the device. Batteries should be changed
when the
icon illuminates. The icon will remain lit until the batteries are changed. If the
battery power level is too low the UltraMax O2 will not power on until the batteries are changed.
5.1 Battery Replacement Procedure
1. Using a #1 Phillips screwdriver loosen the battery door screw and remove the battery
door.
2. Remove the batteries.
3. Insert new batteries ensuring correct polarity.
DO NOT use rechargeable batteries.
4. Replace the battery door and tighten the battery door screw.
5. If the UltraMaxO2 does not power on when done verify the batteries are installed
correctly and that the batteries are fresh.

6 CLEANING AND MAINTENANCE
If you suspect any other surfaces of the device have become contaminated, follow the cleaning
instructions. Cleaning should be performed on an as needed basis as the device does not
directly contact the patient, bodily fluids, or expired gases in normal use.
DO NOT soak or immerse the UltraMaxO2 in fluid.
DO NOT autoclave or expose the UltraMaxO2 to ethylene oxide sterilization.
DO NOT attempt to clean, or service UltraMaxO2 while device is in use.
6.1 Cleaning
Wipe down the exterior surfaces of the UltraMaxO2 with a moist cloth and mild hand or dish
soap (pH 6-8).
6.2 Maintenance
Replace the batteries with high quality AA Alkaline batteries.
DO NOT use rechargeable batteries.
When not in use for periods greater than 30 days, remove the batteries to protect the
•
UltraMaxO2 from potential battery leakage.
Store the UltraMaxO2 between -15˚C and 60˚C (5˚F - 140˚F).
