Is there an easy to to delete a zone on a vista-40?

["Bob Sisson" <Bob@Sisson Family.com>]

Ok, My alarm system has been running flawlessly for several years.  I have
added wireless zones, some new wireless sounders, updated the 2-way stuff
and some others things.

PS..the 2-Way Wirelss Keypad is JUNK, it works for about 15' unlike the
wireless sounders that work like they should anywhere a transmitter will
work. And yes, I reset it, retrained it, retrained it and did everything
everyone told me to do...10' yes, 50' where my last transmitter is, no-way.

QUESTION: Is there an EASY way to completely delete a wireless zone?

In this case Zone 51.  We converted a space and took out access so it no
longer needs monitoring.  I forgot about it until the Battery died and it
sounded a warning about not checking in.... Ooops...

I can find how to edit it, change serial numbers, and lots of other things,
but nothing about how to just delete it.

Thanks
