User Manual Avanti MO7191TW Microwave Oven

A 0.7 to 0.8 cubic feet microwave is usually of the solo grill or convection microwave type that you can actually do baking and cooking with. It's still small enough to use in small apartments and RVs or campers. Vehicles in particular require the 0.7 cubic feet microwave's 700-watt power level.

Many microwaves, particularly modern ones, have a mute function. ... The best way to switch off the beeping on a microwave it to check if it has a silent mode.

To turn the sound on:
1. Press the Setup / Help key.
2. Press the Setup / Help key again.
3. Press the Start / Add Minute key.
4. "Sound on" appears on the display, and the unit should beep when a key is pressed
