Chapter 5 Shooting — Setting of time data
Time code function during battery replacement
The operation of the time code generator will continue by the backup mechanism functioning even when replacing the battery.
The time code of the free run may shift when any item in the [SYSTEM] menu
→ [FREQUENCY]/[FILE FORMAT]/[REC FORMAT] is changed. Set the
power to < j > (ON) again, confirm the time code, and set it again if necessary.
@ @
NOTE
t When the power switch has been switched to < j > (ON) → < h > (standby) → < j > (ON), the backup accuracy of the time code in the free run mode
is approximately ± 2 frames.
Externally locking the time code
The internal time code generator of the camera can be locked to an external time code generator. In addition, the time code generator of an external
equipment 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 genlock, refer to “Selecting external reference signal and genlock setting” (page 137).

External lock operation procedure
To externally lock the time code, follow the steps below.
1
Set the <TCG> switch to <F-RUN>.
2
Set the <DISPLAY> switch to <TC>.
3
Set to the [OTHERS] menu → [GENLOCK] → [GENLOCK] → [GL IN].
4
Set to the [RECORDING] menu → [TC/UB] → [TC IN/OUT SEL] → [TC IN].
5
Input a reference time code and reference video signal that are in a phase relationship (that conforms to time code specifications)
to the <TC IN/OUT> and <GENLOCK IN> terminals.
The built-in time code generator is locked to the reference time code. When approximately ten seconds has elapsed after locking, the externally
locked status will be held even if the reference time code from the external device is disconnected.
f When the input reference signal of genlock is disrupted, recording cannot be performed normally. [TEMPORARY PAUSE]/[IRREGULAR SIG] is
displayed in the viewfinder screen, and the clip is divided. The continuity of the time code is not guaranteed. Recording will be resumed when the
signal returns to normal.
f When the time code is externally locked, the time code is instantaneously locked to the external time code, the same value as the value of the
external time code is displayed on the counter display area. Do not start recording for several seconds until the sync generator has stabilized.
Furthermore, lock the time code to the <TC IN/OUT> terminal signal.
f When externally locking in 23.98p mode, be sure to input non-drop frame time codes. An external lock is not possible using drop frames. When the
external lock is activated, images may look corrupted. However, this is an operation to match the 5-frame cycle so it is not a malfunction.
f When set to the [RECORDING] menu → [PRE REC] → [ON], disrupted images or stopped time codes may be recorded if the time code is slave
locked by entering an external time code to the <TC IN/OUT> terminal right before recording.
