It is annoying as all heck at the beginning but you get used to it. When they are not beeping then you notice it right away. I know on both our presses the only way to "turn them off" is to disconnect and cap the wire going to the speaker. On the anatol you are able to shorten the beep lengths in the menu but not disable it completely. I am no help on the M&R sorry. Doesn't your other press have a beep? Guess I kinda assumed all of them had it.
To dull the beep you can also fold a shirt scrap over a bunch of times and tape it to the speaker, doesn't look pretty but it dulls the sound out.
