I can't turn the voice feature back on. My emerson microwave has an optional voice feature that talks when you hit certain keys. I turned it off when I first got the microwave. Now I can't remember how top turn it back on. Please help. It's not in the owners manual. Instructions to turn the voice on and off were on a separate card that was with the packaging.
