SHOOTING OPERATION

HEADER REC Function

When the REC/VTR trigger button is pressed while the STOP button is pressed, this function first records the color bar video and
the test tone (1 kHz sine-wave) of the built-in signal generator at the beginning of the tape. Then it records the black video signal
and the mute audio signal for the duration specified in advance. When the recording is completed, this device enters the Record-
Standby mode. The time code value at the Record-Standby position becomes the time code specified in advance. (HEADER
