Q: How do you shut off the short loud signal every minute or two that is obnoxious and assume is meant to indicate battery working?

That could indicate you have a low battery. Shut-off the unit and then replace the internal 9V battery. Then you can turn the unit back on and the indicator should go away. If you need instructions on how to do this let visit our website and you can access the installation sheet. Or email us at sales@sti-usa.com.
