Set the time code using the control stick.
f Screen display
- When pushed down to the right, the digit that has been to set (flashing) moves to the right.
- When pushed down to the left, the digit that has been to set (flashing) moves to the left.
- When pushed down toward the top, the value of the digit that has been to set (flashing) is raised by one.
- When pushed down toward the bottom, the value of the digit that has been to set (flashing) is lowered by one.

Press the control stick, enter the values of the time code, and exit the time code settings screen.

Use the <COUNTER> button to display [TC] and confirm that the set value is displayed.
Settable time code range

For 50 Hz:
@
NOTE
t When using with 24P, the time code setting is adjusted in 5-frame units. When 24PN, adjusted in multiples of 4, and when 720/30PN and 720/25PN,
adjusted to even numbers. Also, the time code cannot be set during recording.
t If you exit the time code setting screen without pressing the control stick, the set values are disabled.
Time code function during battery replacement
Even during battery replacement, the backup mechanism functions, allowing the time code generator to continue operating.
When each item of the system mode has been changed, the time code of free run may shift. Turn on the power again, check the time code, and reset it,
if necessary.
@
NOTE
t When the power switch has been switched to <ON> → <OFF> → <ON>, the backup accuracy of the time code in the free run mode is approximately
±2 frames.
Time codes in variable frame rate
f In 24PN, recording is 24 frames, output is 30 frames, which matches 2:3 pull-down images.
f The advance rate of the recording and output time code matches real time only when the image frame rate is 24P. When 60P, recording advance rate
is 60/24 times. In this case, the camera switches to [REC RUN] fixed operation and the time code value that is output when recording starts matches
the recording time code.
f It is the same when shooting in modes other than 30P when in 30PN and shooting in modes other than 25P when in 25PN.

Externally locking the time code

The internal time code generator of the camera can be locked to an external generator. In addition, the time code generator of an external device can be
locked to the internal time code generator of the camera.
Example of connections for external locking
As shown in the figure, connect both the reference video signal and the reference time code.
For details on reference signal and generator lock, refer to "Selection of external reference signal and generator lock setting" (page 87).
r When locking onto an external signal
NOTE
@
t To input or genlock input external time code, set the <IN/OUT> switch to <IN> and select [FREE RUN] in the main menu → [RECORDING SETUP] →
[TCG].
t You can input Y reference signals of HD and composite video signals as reference videos signals.
t When the system mode is 480i (576i) (SD) and 720P, input the composite video signal.
