flash. Please connect the power adapter or charger to power the device in time;
1.6 When the device is not working, the battery in the device is fully charged for

1. Clean the Shell
The outside of the machine should be wiped clean at least once a month. Cut
off the power supply and then wipe it with a slightly damp cotton cloth or
sponge. Be careful not to seep liquid into the cracks of the chassis.
After cleaning, place the machine in a ventilated place for about 2 hours, and
wait until the surface is completely dried before using.
2. Clean the Disposable Oxygen Inhaler
The oxygen inhaler should be cleaned once a week, and the nasal cannula on it
should be cleaned after each use.
Soak the inhaler into vinegar for about 5 minutes, and then rinse with clean
water, or wipe with medical alcohol. It is recommended that the oxygen inhaler
be replaced every 2 months of use. (Note: The inside of the oxygen inhaler tube
should be kept dry.)
3. Replace the Air Intake Filter Pad
Figure 8 - Bottom of the machine
The main function of the intake filter pad is to filter and adsorb dust and
impurities in the air, which may cause a blockage after a long period of use, and
thus affecting the oxygen production effect of the machine. Therefore, it is
recommended to replace it every six months; and if the environment is dusty,
replacing it once a quarter is recommended.
Note that the filter pad can not be washed and reused, otherwise it will affect the
performance and life of the machine!
Replacement method: Remove the battery according to the method shown in
Figure 3, lay the machine flat, and remove the two silicone stoppers as shown in
Figure 8. You will see the round air intake filter pad inside. Take it out with
tweezers, put in the new pad, and finally put the silicone stopper back in place.
4. Battery Maintenance
If the machine is not used for a long time, it is necessary to charge it every three
months to avoid deterioration of battery performance due to long-term low power
or non-use. For each charge, charge to 25%-50% will be fine.
This operation is not required if the product is in normal use.
