HOW TO TURN OFF EVENT BUZZER
All Optiview recorders have a notification system, a.k.a. a buzzer, to let the user know if there is something wrong with the hard drive (HDD). Once the buzzer is triggered it will not turn off on its own until the problem has been resolved. There is, however, a way to turn it off if it has been triggered; Just remember to turn it back on once the issues has been resolved.
