FYI: THERE IS an Alarm on a JBJ ATO

After getting the JBJ ATO i set it up, and after it pumped ~20 gallons of water, i realized that the "alarm" that the product features states will sound once the pump starts, never actually went off...ever.
Turns out you have to open the controller up, and flip the only switch on the board.
I have no idea why they have the switch on the board VS having it on the outside...It's only 4 screws though...
anyway, hope it helps someone.

Good info. for others baloo. I guess it depends on the model of JBJ ATO. I used to have one of those, but I never saw anything that indicated that it had an alarm. It does sound kind of stupid to have it on the inside

its in the instructions (or online cant remember). the older models you actually had to remove the little speaker but the last one I had (to my suprise) had a switch inside.
