If there are dusts or foreign objects in the particle
sensor, the dust density may be detected high, so clean
periodically to remove the dust.
* If not cleaned periodically, the particle sensor performance will
be degraded.
* The cleaning cycle may differ depending on the environment.
Clean more often in very dusty environments.
* Do not let dusts drop into the air vent hole when you clean it.
1. Use a vacuum cleaner or soft brush to clean the dust
outlet and dust inlet.
* Use the lowest power of the vacuum cleaner to clean.
2. Clean the dust outlet and dust inlet with wet cotton
swab, then wipe it off with dry cotton swab to
remove moisture from it.
