Jam Zeros

This menu selection resets the internal generator to zero.
menu selection

Jam Value

Press the enter soft key (TONE key) or the Multi-Function Rotary Switch button to jam the user-
entered time code start value into the internal generator.

Edit Value

This menu allows the user to set any valid time code value (00:00:00:00–23:59:59:29) for entry with
the jam value selection above. The initial screen of this menu shows the currently set value as well
as the current time code setting of the 788T. Press the Multi-Function Rotary Switch or the enter key
(tone key) to enter into edit mode. The user can set the time code numbers in pairs (hours, minutes,
seconds and frames). Once (DONE) is selected the value is available to jam into the internal generator
with the jam value selection.
A value is not jammed into the 788T time code generator until JAM VALUE is selected.

User Bits

The 788T has seven user-selectable user bit modes. Time code user bits are a portion of the time code
data which can be allocated however the user chooses. Commonly, user bits carry information such
as the date, take, sound roll, or camera roll number.
User bits are edited from the EDIT U-BIT selection in the jam menu. Press the enter soft key (TONE
key) or the Multi-Function Rotary Switch to enter user bit edit mode. The screen will show the for-
mat and setting of the user bits. Using the Multi-Function Rotary Switch or the Up and Down Arrow
soft keys, user bit digits can be edited (in pairs). Once DONE is selected, the user bits are set. If editing
is not available in the selected user bit mode "NO USER EDITS" will appear in the screen.

NTSC Standard Def Video Production

NTSC video uses a frame rate of 29.97 frames per second. Unfortunately, that leaves 108 frames per
hour unaccounted. To keep 29.97 time code in sync with "clock" time, the concept of "drop frame"
was devised. Two frames are dropped at the top of each minute not divisible by 10. 54 drops per
hour x 2 frames = 108 frames per hour.
To sync the 788T to a video camera, fi rst determine if the camera is in drop frame or non-drop frame
mode. If you, the DP or the producer are unsure about what setting to use, check with post-produc-
tion, if possible.
As a rough guideline, video for NTSC broadcast is drop-frame. Whether at drop or non-drop rates, make
certain all time code devices are at the same rate.
1. Set the 788T to either 29.97DF or 29.97 respectively.
