Battery Low

Hello,

The message “battery Low” is displayed when starting my MD. I don’t have too much time at the moment to look at battery change, but I just wanted to know one thing: if you don’t change the battery once it’s dead, what happens? We can’t save anymore, right? But what has already been saved (the sequences) and the machine, I imagine that all this continues to work normally?
Just to procrastinate a little more…
