[Yaesu] VX-7R Beep

[K8RI]

I've had this happen twice over the years I've had the VX-7s and I've 
been unable to find it in the manual.  Some how the one HT has been 
programmed to "beep" every time the PTT button is pushed. This is both 
audible and transmitted.  It's really annoying. <:-))

I know there has to be a key sequence to turn this on and off, but I've 
never found it.
Anyone have a page in the manual where I can find it, or just the sequence.

I use them so seldom I have to get the manual out every time I change 
anything.

Thanks and 73
