To those of you familiar with this machine, does your audible alarm work? I have a new one and am frustrated that there is no audible alarm when the bobbin is running out. I just sewed a very long seam with lots of points to match only to discover the bobbin was empty! The window shows a low bobbin but it doesn't catch my eye the way an audible alarm would get my attention. I have gone into the menu and made sure the box is filled in, indicating the alarm is on, but no alarm. Am I missing something?
