3.  Update Details

3.1 The update enhances the PTT priority system so that in 'local'
    control mode, a PTT from the Transceiver front panel will 
    always over-ride an active PTT from another source; Repeat, 
    Line Interface or Linked Radio.  Previously, once the front 
    panel PTT was asserted it waited for an existing PTT to be 
    de-asserted before becoming active.  

3.2 This update includes a change in the way that CTCSS tones 
    are generated and detected.  CTCSS tones are now more accurate 
    than with previous versions but for optimum performance use 
    of CTCSS tones 67, 71.9, 82.5 and 85.4 Hz should be avoided.  

3.3 The update also fixes a bug when the repeater is used in an 
    a simplex configuration when the transmit carrier may, 
    sporadically, be seen to be off frequency when keyed by the
    Line Interface.

3.4 If used in Link Radio mode both transceivers must use this 
    release.
