67Externally locking the time code1 Set the POWER switch to ON.2 Set the TCG switch to F-RUN.3 Set the DISPLAY switch to TC.4 Supply the reference time code and referencevideo signal which are in a phase relationship thatsatisfies the time code standard to the TC INconnector and GENLOCK IN connectorrespectively.When the external lock operation is performed, thetime code is instantly locked to the external time code,and the same value as the external code valueappears on the counter display.Do not set the unit to the recording mode during thefew seconds it takes for the sync generator tostabilize.User bits setting when the time code is externallylockedWhen the time code is externally locked, only the timedata is locked to the time data of the external timecode.This means that the user bits can be set separately foreach unit.The user bits can also be locked to the user bits of theexternal time code. For details, consult your dealer.To release the external lockFirst stop supplying the external time code, and setthe TCG switch to R-RUN.When switching the power from the battery to anexternal power supply while the time code isexternally lockedIn order to ensure the continuity of the time codegenerator’s power, connect the external power supplyto the DC IN connector, and then remove the batterypack. If the battery pack is removed first, noguarantees can be made for the continuity of theexternal locking of the time code.Gen-locking of the camera unit while the timecode is externally lockedWhile the time code is externally locked, the cameraunit is gen-locked by the reference video signal whichis supplied to the GEN LOCK IN connector.O When the frame rate is set to 24 fps, this unit willperform the processing in the non-drop frame modein order to maintain the continuity of the frameseven when the time code has been set to the dropframe mode.Furthermore, when the frame frequency has beenset to 60.00 Hz as well, the unit performs theprocessing in the non-drop frame mode.If an external time code generator is used, set it tothe non-drop frame mode.O Use the same frame frequency setting for thereference time code and reference videos signal asthe unit’s setting.When the frame rate is used at 24 fps, the imagemay be disturbed if the frame frequencies differ.Setting the time data (continued)321GENLOCK INTC INThe time code generator of the VTR unit can belocked to an external generator.Example of connections for externallockWhen locking to an external signalReferencetime codeReferencevideo signalThe built-in time code generator is now locked to thereference time code.About 10 seconds after locking, the external lockstatus will be retained even if the connection of theexternally supplied reference time code isdisconnected. However, the servo lock will be subjectto disturbances if it is connected or disconnectedduring recording (REC).
