2) The chroma gain adjustment screen will appear.
3) When using an oscilloscope (Fig. 6-2):
Press the D or U key on PC to set the red level on waveform as
specified in Table 6-4 (rough adjustment).
Then, while holding down the Ctrl key on PC, press the D or U key
to set the red level on waveform as specified in Table 6-4 (precise
adjustment).
When using a vectorscope (Figs. 6-3, 6-4):
Press the D or U key on PC so that the red vector is as specified in
Table 6-4 with respect to burst vector (rough adjustment).
Then, while holding down the Ctrl key on PC, press the D or U key
so that the red vector is as specified in Table 6-4 with respect to
burst vector (precise adjustment).
4) Press the Enter key on PC: The PC display will switch from the data
write screen to adjustment complete screen.
5) Press any key on PC to restore the camera adjustment menu screen.
