I have no idea what this new to me integra  keeps beeping about.  It worked fine for the first several fields and now suddenly it's beeping like a backup alarm and the screen shows the booms are in front of me.  It does seem to be spraying properly while it does that.

It's not the tank level alarm, or the rate alarm.  I assume it's the back up alarm as the screen I think shows me going backward instead of forward.

it didn't come with any manuals to look this up in.
