To set the frame mode (DSR-50 only)
Set TC FORMAT on the TC/UB SET menu to switch
the frame mode.
AUTO: Automatically sets the mode in accordance
with the inserted cassette.
If nothing is recorded on the tape, the mode is set
to the non-drop frame mode. If the unit cannot
read the frame mode correctly in the tape, the unit
will use the mode that was set in the last position
it was able to read correctly on the tape. If you
turn the power on/off or remove the tape, the
mode of the last position it was able to read
correctly is cleared and the mode is set to the non-
drop frame mode. If TC MAKE is set to PRESET,
the mode is set to the non-drop frame mode.
DF: Selects the drop frame mode.
NDF: Selects the non-drop frame mode.
Note
In a DV format recording, the drop-frame mode is
used automatically.
To set the advancement mode
Set TC RUN on the TC/UB SET menu to switch the
advancement mode (counting up).
REC RUN: Time code advances only while
recording.
FREE RUN: Time code advances even when the
unit is not recording. This mode is used to set the
current time as the initial time code value, or to
synchronize the internal time code to an external
time code.
Notes
¥ If you set the advancement mode to FREE RUN, the
time code will be updated by the internal clock during
the unit power is off. The time code may have been
delayed or advanced somewhat if you turn on the unit
power again, play back a tape, or set the INPUT
SELECT selector to DV.
¥ If the internal backup battery charge is exhausted, the
time code of the FREE RUN setting will be
initialized. The internal backup battery is fully
charged if you connect the power to the unit for about
10 hours. A fully charged internal battery can run for
about one month.
To set the time code when the recording
starts
Set TC MAKE on the TC/UB SET menu to select the
time code when you start recording.
REGEN: The time code value is set to continue the
time code from the time code already recorded on
the tape. If you start recording from a blank
portion of the tape, the time code starts from
00:00:00:00.
PRESET: The time code value is set to the time code
from the value set in PRESET in TC PRESET on
the TC/UB SET menu.
To switch the time code output when
playing at various speeds (JOG)
Set JOG TC OUT on the TC/UB SET menu to control
the time code output from the TC OUT connector
when the tape is played at various speeds.
OFF: Does not output the time code.
ON: Outputs the time code.
Note
The continuous time code is output only when the tape
is played at normal speed. When the unit is in the jog
or search mode, discontinuous time code is output.
To set the current time in the user bits
You can set the current time in the user bits by setting
the UB TIME on the TC/UB SET menu.
OFF: The value set in PRESET in UB PRESET on
the TC/UB SET menu is set to the user bits.
ON: The value set in CLOCK SET on the OTHERS
menu is set to the user bits.
Note
This function is available only when TC/UB IN on the
TC/UB SET menu is set to INTERNAL or TC EXT.

To select the time code/user bits to record
on the tape
You can set the time code and user bits to record on
the tape by setting TC/UB IN on the TC/UB SET
menu.
INTERNAL: Uses the internal time code/user bits.
TC&UB EXT: Uses the external time code/user bits.
TC EXT: Uses the external time code and internal
user bits.
UB EXT: Uses the internal time code and external
user bits.
Notes
¥ This unit has a DV IN/OUT connector. The time code
input or output is different when you connect the unit
to an external device via this DV IN/OUT connector
or via another input/output connector.
For details, see DSR-50/50P time codes on page 62
(GB).
¥ The time code output from this unit has some
restrictions.
For details, see Notes on the Time Codes on page 63
(GB).

Synchronizing the Time Codes
You can synchronize the internal time code generator
of the unit by inputting an external time code signal
(LTC).
Connecting to the Time Code
Generator
To synchronize the internal time code to
an external time code
1
Set the INPUT SELECT selector to other than DV.
2
Input an external time code (LTC) signal to the TC
IN connector of the unit.
3
Set TC/UB IN on the TC/UB SET menu to
TC&UB EXT or TC EXT.
The internal time code generator locks onto the
external time code and starts advancing. Once the
internal time code generator has become
synchronized in this way, you can disconnect the
external time code input and this unit will maintain
the time code from the external device.
Notes
¥ This unit has a DV IN/OUT connector. The time code
input or output is different when you connect the unit
to an external device via this DV IN/OUT connector
or via another input/output connector.
For details, see DSR-50/50P time codes on page 62
(GB).
¥ The time code output from this unit has some
restrictions.
For details, see Notes on the Time Codes on page 63
(GB).
To confirm external synchronization
Before you start recording, check that the internal time
code is synchronized to the external time code.
Press the STOP button to put the unit into stop mode,
then press the REC button.
Look at the time counter display and check that the
time code value displayed there matches the external
time code value.
