The ONA Mist Dispenser has an electronic eye that senses bright light or low light. You can set it to spray only in the dark (low light) or during the day (or when lights are normally on). The third option allows you to set it to spray 24 hours per day. The spray is metered out in three adjustable time intervals - 7.5 minutes, 15 minutes, or 30 minutes. Operating on batteries, the ONA Mist Dispenser can be placed anywhere.
Customers often think the Dispenser isn't working when they install the batteries.
It is likely that it just seems like it is not working as the unit does not spray right away after the batteries are inserted into the unit and the door closed on the unit. There is a trigger switch that engages when the door is closed (often mistaken for a switch to push to make the unit spray once).
With new batteries and the door closed on the unit, it should begin spraying after the time interval that was set on the inside of the unit. Also make sure the unit is set to day or 24 hours if you are just testing to see if it is working.
