BrailleNote Apex making error beep when turned on

Hi all,
I have a braillenote Apex running KeySoft 9.51 and I'm using in with an iPhone on iOs 17.1. I'm having this weird issue with my Apex that happens every time I turn it on. It makes the error beep noise (those of you who have used a braillenote Apex in the past know what I'm talking about.) But the other weird part about it is that it only happens if I turn the Apex off while it's in Terminal mode. If I exit terminal mode before shutting off the Apex, it doesn't make the error beep noise. Is there any way to stop this from happening without having to exit Terminal mode before shutting off my Apex? I tried factory resetting the Apex with no luck.
Thank you all for any suggestions you may have.
