  TIME OUT TIMER


  This option, when enabled, permits radio transmission for the time set in
  the MAIN/CHANGE/PER-RADIO Screen - Time Out Timer entry.  If the radio is
  transmitting, and the Time Out Timer period expires, the radio is automati-
  cally dekeyed, and a continuous alert tone is heard for as long as the PTT
  is pressed.  To continue transmission, the PTT must be released and the
  radio re-keyed.
