• Do not clean the sensor part with volatile materials such as alcohol and acetone, use only water.
• When foreign material(dust) remains around the dust sensor lens, the contamination level status might not be
changed from contamination status. In that case, clean the sensor again.
• Clean the sensor part every six months. However, the cleaning period can vary according to the surrounding
environment and hours of usage, so this period should be shorter in a dusty environment.
