13. om OFF state 40 may be entered from the adjust zoom factor state 46 by adjusting the zoom factor to 1x When the inner knob 16 stops turning the zoom ON state 44 stores the current zoom factor as the prior zoom factor Pressing the zoom button 18 off when zoom is ON always returns to the zoom OFF state 40 Turning the outer ring 14 when zoom is ON and pan is OFF enters an adjust position state 48 in the zoom window 34 the positioning rate being a function of the number of positions from neutral the outer ring is turned When the outer ring 14 is turned farther an adjust zoom box state 50 for the main window 32 is entered Turning the outer ring 14 back returns to the adjust position state 48 for the zoom window 34 Releasing the outer ring 14 returns to the zoom ON state 44 From either of the zoom ON states 48 50 pressing the pan button 20 on enters a pan play state 52 where the wave form automatically scrolls across the display in the zoom window 34 with the zoom box 30 moving correspondingly in the main window 32 Pressing the pan button 20 off pauses the scrolling and returns to the zoom on state 44 and pressing the pan button on re enters the pan play state 52 with the 20 25 30 35 40 45 50 55 60 65 4 prior pan rate From the pan play state 52 turning the outer ring 14 through the first set of positions enters an adjust pan rate state 56 where a pan rate for the zoom window 34
