Recently, when I submit a job to my A1 it does 2 long beeps and then 3 short beeps while going through the start up before actually extruding any filament. The jobs run and complete with no issue and some of the longer ones have long beeps during the build. There are no error messages on the touchscreen or on my PC screen with Bambu Studio running. I’d say it occurs on 95% of the prints I do. Any ideas of why this is happening?
I have a YouTube video with the beeping. A long beep occurs at 1 minute, 3 seconds for about 22 seconds and again at 1 minute 50 seconds for about 30 seconds and 3 short beeps occur at 2 minutes, 21 seconds for about 4 seconds.
Thanks for any help.
The 1st beeps is Bambu receiving the file you sent & unzipping it.
The 2nd & 3rd beeps are Errors, you need to click on the Assistant to read what it is.
Ever notice that once you post an issue on the forum, the cause of the issue becomes apparent and you feel silly for posting in the first place? Well, that has just happened to me. 
The cause of the beep was my UPS, not the A1. The UPS is tucked under my desk and not easily seen. I just happened to be in a position to see it when I turned on some lights that are connected to the UPS’s surge ports and the beep happened. The UPS also had a flashing light while the beeping was occurring. When I started my next print, I made sure I was in a position to see the UPS’s light. When the beeping happened at the start of the print, the UPS light was flashing. I also got closer to the UPS and could definitely hear the beeping coming from it. So, problem solved.
Also, thanks to lion7718 for the suggestions.

The UPS might have been the cause of the beeps, but you still had an error in your 2nd-3rd video or was that just a coincidence…??
Coincidence. The message is that the AMS ran out of filament and switched to another spool. Is there anyway to remove that message or will it go away on it’s own?
It will go away when the print is finished or you restart the printer.
