Kenwood TH-27A - Manual (Page 41)

The Tone Alert function will provide an audible "alarm"
to signal when someone is transmitting on the frequency
you are monitoring. During T.ALT function you will not
hear voice communication. When used in conjunction
with the CTCSS, DTSS, or Paging function this would
allow the transceiver to act similar to a private paging
system!

must be present for approximately 1 second in
