I have a Zoji ABM and I also wear a hearing aid. I cannot hear the high
pitch beep when it is time to add raisins.
This is what I do with raisin bread and it might help with adding M&M's.
When the knead cycle stops (after about 45 minutes in my machine) I remove
the pan and place the dough on a floured surface. I remove the paddle from
the pan, since it is no longer needed, and place the empty pan back in the
machine.
I form the dough with my hands into a rectangle about 6 inches by 18
inches. I spread the raisins evenly over the dough and pat them into the
dough with my hands. Then I sprinkle with the cinnamon listed in the
recipe.
Now I roll the dough up jelly-roll fashion shaping it with my hands so it
is only about 4 inches high. Then I place it back into the pan for the
raising and baking.
With this method the raisins are evenly distributed and do not get
mashed-up by the paddle.
