R.F. Says: The VX-120/170 does not recognize the order of the 1st tone and the 2nd tone. In

to be identical.

Paging Answer Back

same CTCSS tone pair. This tone pair will open the Code Squelch of the calling station. If you
prefer, you can have the VX-120/170 respond to page calls automatically ("transpond").
