Wirhout a beep I can't say "Pizza's done!" when ever I microwave anything that isn't pizza. Food that was started before leaving the room might grow cold and forgotten without the reminder beeps.
I was able to turn off the beep on mine. Was no secret though, was explained in manual. Now if I ever get another microwave I'll know to look up how to turn off the beep.
Same. I feel a bit ridiculous saying it, but as a frequent late night snacker with sleeping people in the house, it has changed my life. I do what I want care free now while my food is heating. And it's so simple like you said, just hold 8 to toggle the setting.
