  must be enabled for any DTMF features to function.  This option can not be
  enabled at the same time as Unit ID on Dekey(Digital Signalling feature).

  the DTMF front cover option.  This feature allows automatic dialing of a
  phone number stored in any one of the 10 memory locations available.  These
  numbers can be entered by the MT1000 Radio Service Software or can be user
  programmed in the field.  If enabled, the * and # keys perform as dual
  function keys.  The * is used to perform Autodial and the # is used for
  Indefinite Pause.  If disabled, the * and # function only as the
  corresponding DTMF tone

  feature.  When enabled, the user can program memory locations 1 and 2 with
  pre-set numbers which can not be changed by the user of the radio.  These
  numbers can only be changed by the MT1000 Radio Service Software

  then begin dialing numbers.  The PTT can be released any time after dialing
  has begun and as long as the next number is dialed within 2 seconds, the
  radio will remain in transmit.

  tones.  Pre-Emphasis causes the DTMF tones to be transmitted at a 6dB per
  octave pre-emphasized level.

  DTMF TONE TYPE - This feature has two choices:  timed tone or continuous
  tone.  If timed tone is selected, each time a DTMF key is pressed, a DTMF
  tone of a specific time will be emitted.  These tone times are determined
  by TONE ON TIME and TONE OFF TIME features in the DTMF Options screen.  If
  continuous tone is selected, the tone will remain on as long as the DTMF
  key is pressed.  The tone will stop as soon as the key is released.

  TONE ON TIME - This feature allows the user to enter the TONE ON TIME if
  Timed Tone is selected in the DTMF TONE TYPE feature.  The range of tone on
  lengths allowed is 100 ms to 850 ms in increments of 50 ms.

  TONE OFF TIME - This feature allows the user to enter the TONE OFF TIME if
  Timed Tone is selected in the DTMF TONE TYPE feature.  The range of tone
  off lengths allowed is 100 ms to 850 ms in increments of 50 ms.
