     ^rExtended first tone duration^r
     
     To  program the duration of the encoder and/or decoder extended  first
     tone. 

     The defined time will be used as the duration of the first tone  of  a
     tone sequence, if the sequence is preceeded by a '+' sign. 

     Valid range for the extended first tone duration is:

     ^rEncoder^r : 5ms - 7500ms, in 1ms steps.
     ^rDecoder^r : Select 5 tone system duration - 7500ms, 1ms steps

     The default extended first tone duration is 600 ms. 


     Due  to  the  radio  software  decoder  algorithm  generating the tone
     duration,  not every toneduration can be achieved exactly.  The  Field
     Programmer   computes  the codeplug data from the desired decoder tone
     duration and recomputes the  real  decoder  tone  duration  from  this
     data.
