• Are the batteries inserted correctly?
• Is a fluorescent lighting in the room flickering due to service
life? (Refer to E-7,E-10)

A clicking or ticking sound is
heard from the unit
• Clicking sound is emitted when the unit is in the Ion Control

If the sound is irritating, set the unit away from you.
• Ticking sound is emitted when the unit is generating ions.

ozone will break down quickly and will not accumulate in the
room environment.
