Use Tips
Ⅰ.Battery Charging
1. Due to transportation control and other reasons, the built-in battery of the
device only retains power for testing when leaving the factory, or there is no
power at all, so the device needs to be charged before first use.
2. The built-in battery will only be charged automatically when the AC adapter is
used; if the vehicle power cord is used, it can only supply power to the device and
cannot charge the built-in battery.
3. This device currently does not support the use of non-built-in batteries.
4. The AC adapter and the car power cord will share the same power socket, so
only one of them can be used at a time.
5. When the power of the built-in battery is less than 25%, the power indicator will
flash to remind you to connect the power adapter or charger to power the device.
6. When the device is not working, the battery in the device will fully charge for
about 4-8 hours. When the device is in operation, the charging time will be
extended to 9 hours.
7. When using the vehicle power cord in a car, turn on the engine. When the
engine is off, the device cannot be used to prevent the battery from losing power
in the car. And only the dedicated car power cord can be used.
Ⅱ.Guidelines for Using Electromagnetic Environment

environment or other electrical products, please keep this machine and other
household appliances at least 30cm apart during use.

Ⅰ. Clean the Shell
Wipe and clean the outside of the machine at least once a month: first cut off the
power, and then wipe with a slightly damp cotton cloth or sponge. Be careful not
to let liquid penetrate into the cracks of the chassis.
After cleaning, place the machine in a ventilated place for 2 hours, and wait until
the surface is completely dry before using it.
Ⅱ. Cleaning the Disposable Oxygen Inhaler
The oxygen inhaler is cleaned once a week, and the nasal suction tip on the
oxygen inhaler should be cleaned after each use.
It can be soaked in white vinegar for about 5 minutes and then rinsed with water,
or wiped 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)
Ⅲ. Battery Maintenance
If you do not use the machine for a long time, you need to charge the device
once every three months to avoid the battery's long-term low power and non-use
which may cause a decrease in battery life. Each time the battery is charged to
25% to 50%.
