Set the POWER switch to ON.
2
Set the TCG switch to F-RUN.

Supply 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.
3
Set the DISPLAY switch to TC.
Operating procedure for external locking
Follow the steps below for external locking.
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.
O When the power of the unit is turned off, the time code is
unlocked.
O The accuracy of the time code is ± 20 seconds a month.
<Note>
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.
Concerning the user bits setting during external
lock
When the unit’s time code is externally locked, only the time
data is locked to the time data of the time code supplied from
the external source. This means that the user bits can be set
separately for each component.
When the <TC/UB> screen is opened from the VTR menu
page and EXT is selected as the UB MODE item setting by
performing menu operations, the user bits can also be locked
to the user bits of the time code supplied from the external
source.
To release the external lock
First stop supplying the external time code, and set the TCG
switch to R-RUN.
