NewRPL announciator question

[nickapos]

Hello to everyone, sorry for the simple question but i have not been able to find a clear answer in the documentation.
On my 39gs NewRPL calculator I can see that the announciator ((*)) is constantly on.

According to github this should be the busy announciator, but why is it always on even when there is no computation happening.

Am I reading this right?
I wonder if I have something on that is constantly running and consume energy or if this is normal.

Thank you very much
