The Oser OM1101NOE is a microwave oven equipped with a 12 inch revolving plate and sleek stainless-steel finish. When a user presses the options on the keypad of the microwave, a 'beep' sound can be heard. If this beeping is either too loud or annoying, there is the option to mute it. With a simple procedure you can mute the beeps and get back to your microwave cooking in minutes.

Press and hold the "Power/Off" button."
Press and hold the "0" button in addition to the "Clear/Off" button.
