JAM
Indicates the unit is operating in the continuous jam sync mode.
When the JAM indicator is blinking, it indicates a variety of
problems in the jam sync process. If it is blinking on an irregular
basis, the reader could be receiving bad code, there may be a
discontinuity in the code, or the code was recorded in a different
standard than the 4025 is locked to.
VITC
Indicates when the VITC keyer is enabled.

each video frame. i.e. NTSC - 30 frames per second, PAL - 25
frames per second.
PULL
NTSC: Indicates that the telecine is set to transfer for a 24 film
frame per second transfer to NTSC video.
Setting the transfer rate is accomplished by using FILM RATE
item on the FILM pulldown menu. The 4025 may be set to
either 24 or 30 FPS transfer rates, or may be set to
automatically detect the transfer rate in use by the telecine.

PAL: This LED should always be Off, as the transfer rate is
always set to 25 FPS.
The key to the operational flexibility of the 4025 Film Footage Encoder lies
in the powerful Format menu system. . The format menu uses the built in
character generator and provides an quick, intuitive method of configuring
4025 Film Footage Encoder, guiding you to the correct setup for your
application. The six keys in the format key group (FORMAT, SELECT
) are used to cycle through the various items on the programming
menu.
The 4025 menu system consists of three drop down menus. The titles of
each of the drop down menus is shown on the top line of the character
display. Selecting an item on one of the drop down menus reveals a sub-
menu showing the choices for that item. Figure 0-8 is an overview of the
on screen menu system, and shows all the menu choices and where you
will find the menu items. Note that some menu choices will be hidden
depending on the programmed mode of operation.
The TIMECODE drop down menu is for overall operation modes such as
selecting which information is put into the time and user bits, drop frame
mode for the generator, setting reader modes, setting VITC line numbers,
etc. The FILM drop down menu is used to set up specific film number
