ing on whether ABS-13 or ABS-23 has
been selected. The value of
xx
varies, depend-
ing on the starting “hour” chosen.
If you select
ABS-13 or ABS-23, use the
UP
and
DOWN
keys to select the starting hour.
In the illustration above, the starting hour is 0.
8.1.3 Selecting a timecode type
The RC-898 can work with a number of different
timecode types, as shown by the
TC
indicators
[7].
The
29
on the RC-898 panel is an abbreviation for
“29.97”. The
DF
indicator will light if the time-
code is in drop-frame format.The supported types
are therefore:
To select or change the timecode type used by a
DTRS unit:
1) From menu group 5, move the cursor to
TC Frame and press
SELECT
:
2) Use the
SHIFT
ed
UP
and
DOWN
keys (
NEXT
and
PREVIOUS
) to select the unit where you
will make settings.
3) Use the
UP
and
DOWN
keys to change between
the following settings:
•30 DF
•30 NDF
• 29.97 DF
• 29.97 NDF
•25F
•24F
These types will not, of course, affect the type of
any timecode which has already been used to
stripe a tape.
They are used for the type of timecode which will
be produced by the internal timecode generator of
a DTRS unit (DA-98 or SY-88) or the synthesis
from ABS timecode of these units.
8.1.4 Setting the generator start time
The DTRS unit’s internal generator can be set in
the following way:
1) From menu group 8, move the cursor to
Gen
Start, and press
SELECT
:
2) Enter the generator start time using the
numeric keypad [16].
3) Press and hold down
SHIFT
and press
ENTER/
LOAD
to transfer the value to the display
screen.
You can also use the cursor keys and the display
screen to set the value here.
We suggest that you choose a value such as
00:57:00:00
, allowing a few minutes of lead-
in on the tape before the program material starts.

NOTES
The frame value at the bottom right of the screen is not set
here. The procedure for setting this is described in detail in
8.1.3, “Selecting a timecode type”, and is accessed from
menu group 5.
If the timecode source is synthesized ABS timecode, the
timecode type may be changed by changing the timecode
type of the ABS “timecode”. It is not possible to receive one
type and convert it for recording, however. If timecode is
being recorded from an external source, thetype cannot be
changed.
