standards to be used: 24, 25, 30, and 29.97 (drop frame) F.P.S. (frames per
second). The required rate can be selected from the Machine Defaults page
which is accessible from the main Defaults page. In addition, the machine
type and dropout limit are selected from this page.
Time can be entered/displayed as timecode or feet and frames.
A box is displayed with time fields expressed in hours, minutes and seconds

Tenths of frames are preceded by a decimal point.
External operation provides the possibility of controlling another transport from
