Setting the time data
When the user’s bit and time code are both to be
used, the user’s bit is set first.
If the time code is set first, the time code generator
will stop while the user’s bit is being set so that the
time code setting will be off.
The time code setting range extends from 00:00:00:00
to 23:59:59:29.
Setting the user’s bit enables information such as
memos (dates, times) up to 8 digits in hexadecimal
notation to be recorded on the sub code track.User’s bit memory function
The user’s bit settings (except for the actual time) are
automatically saved in the memory and retained even
after the power is turned off.

OWhen DATE is selected from the UB MODE items,
the real time operations for year/month/day/time of
the TIME/DATE screen are adhered to. 
OWhen TIME is selected from the UB MODE items,
the real time operations for hours/minutes/seconds
of the TIME/DATE screen are adhered to.
Setting the user’s bit
1Set the DISPLAY switch to UB.

Externally locking the time code
1Set the POWER switch to ON.
2Set the TCG switch to F-RUN.
3Set the DISPLAY switch to TC.
4Supply the reference time code and reference
video signal which are in a phase relationship that
satisfies the time code standard to the TC IN
connector and GENLOCK IN connector
respectively.The built-in time code generator is now locked to the
reference time code.
About 10 seconds after locking, the external lock
status will be retained even if the connection of the
externally supplied reference time code is
disconnected.  However, the servo lock will be subject
to disturbances if it is connected or disconnected
during recording (REC).

When the external lock operation is performed, the
time code is instantly locked to the external time code,
and the same value as the external code value
appears on the counter display.
Do not set the unit to the recording mode during the
few seconds it takes for the sync generator to
stabilize.
User’s bit setting when the time code is externally
locked
When the time code is externally locked, only the time
data is locked to the time data of the external time
code.
This means that the user’s bit can be set separately
for each unit.
The user’s bit can also be locked to the user’s bit of
the external time code.  For details, consult your
dealer.
To release the external lock
First stop supplying the external time code, and set
the TCG switch to R-RUN.
When switching the power from the battery to an
external power supply while the time code is
externally locked
In order to ensure the continuity of the time code
generator’s power, connect the external power supply
to the DC IN connector, and then remove the battery
pack.  If the battery pack is removed first, no
guarantees can be made for the continuity of the
external locking of the time code.
Gen-locking of the camera unit while the time
code is externally locked
While the time code is externally locked, the camera
unit is gen-locked by the reference video signal which
is supplied to the GEN LOCK IN connector.
