Setting the Time Data
Setting the Time Code
When using both the user bit and the time code, set the user bit first. If the time code is set first,
the time code generator will stop while the user bit is being set, causing the set time code to
become inaccurate. The time code can be set within the range of 00:00:00:00 to 23:59:59:29.
1Set the DISPLAY switch to TC.
2Set the TCG switch to SET.
3Set TC MODE on the FUNCTION 3/5 page of the setting menu to DF or NDF. Select DF
when the time code is to be advanced during drop frame mode, and NDF when the time
code is to be advanced during non-drop frame mode.
4Set the time code using the SHIFT/ITEM, UP and DOWN buttons.
SHIFT/ITEM button:This is used to cause the digit which is to be set to flash. Each time it
is pressed, the flashing digit moves to the right.
UP button:This increments by 1 the figure of the flashing digit.
DOWN button:This decrements by 1 the figure of the flashing digit.
5Set the TCG switch.
Set the switch to F-RUN when the time code is to be advanced regardless of the VTR’s
operation.
Set the switch to R-RUN when the time code is to be advanced only while recording is in
progress.
Time code status during battery replacement
The back-up mechanism functions even while replacing the battery to allow the time code gen-
erator to continue operating for extended periods of time (approx. 1 year).

Setting the Time Data
Setting the User Bit
Setting the user bit allows up to 8 digits of hexadecimal data such as memos (date, time), etc. to
be recorded in the sub code track.
1Set the DISPLAY switch to UB.
2Set the TCG switch to SET.
3Select the UB MODE on the FUNCTION 3/5 page of the setting menu.
4Set the user bit using the SHIFT/ITEM, UP and DOWN buttons.
SHIFT/ITEM button:This is used to cause the digit which is to be set to flash. Each time it
is pressed, the flashing digit moves to the right.
UP/DOWN buttons:These increment/decrement by 1 the figure of the flashing digit.
The hexadecimal characters A to F appear as follows.
5Set the F-RUN/R-RUN switch to F-RUN or R-RUN.
User bit memory function
The user bit setting (except for the real time) is automatically stored in the memory and held
even after the power is turned off. However, care should be taken as the settings are not stored
in the memory if the time from when the power was turned on until the setting operations are
completed and the power is turned off is less than 20 seconds.

ÁWhen REAL has been selected for UB MODE, the values set for HOUR and MINUTE on the
TIME/DATE page apply.
ÁIf REAL has been selected for UB MODE and the DISPLAY switch is set to UB, the LCD dis-
play is held when the menu switch is set to SET.

Setting the Time Data
4
Supply reference time code and reference video signals with a phase relationship which
meets the time code standards to the TC IN and GENLOCK IN connectors, respectively.
This locks the built-in time code generator to the reference time code. After about 10 seconds
have passed since the time code generator was locked, the external lock status is maintained
even if the external reference time code is disconnected. However, if the reference time code is
disconnected during recording (REC), the servo lock will be thrown out of order.
|Note{
When the external locking operation is performed, the time code is locked instantly to the exter-
nal time code and the same value as the external code value appears in the counter display
position. Do not set the VTR to recording mode for several seconds until the sync generator has
stabilized.
Setting Time Data
User bit setting during external locking
When the time code is locked to an external source, only the time data is locked to the time data
of the time code from the external source. Accordingly, the user bit can be set independently for
each unit. The user bit can also be locked to the user bit of the time code from the external
source.
ÁConsult your dealer for a detailed explanation.
Releasing the external lock
Stop supplying the external time code and then set the F-RUN/R-RUN switch to R-RUN.
Switching the power supply from the battery to an external power supply during external
locking
In order to maintain power supply continuity for the time code generator, connect the external
power supply to the DC IN connector before unplugging the battery pack. If the battery pack is
unplugged first, the external locking continuity of the time code cannot be assured.
Synchronizing the camera section to an outside source during external locking
While the time code is locked to an external source, the camera section is genlocked by the
reference video signal input to the GENLOCK IN connector.
Using the user data
The data which has been set on the setting menus can be saved in the user area of the cam-
era’s memory and read out when required. This data can be called to establish speedily the ap-
propriate setup statuses.
User data operations
A menu is used to save the setting data in the user area of the camera’s memory and read out
the data which has been saved.
Saving the user data
1Use the menu’s INITIALIZE screen to save the user data.
2Set the MENU SET/OFF switch to SET to open the menu while pressing the SHIFT/ITEM
