1) Set the color temperature conversion filter (LB165) on the lens.
2) While shooting the gray scale normally, observe the monitoring screen of the vector
scope. By rewriting the data, position the luminescent spot so that the following burst
ratio is obtained.

1) Establish the normal mode (by writing data " FF" at address "0000".
2) While shooting the gray scale normally, observe the video output using the
oscilloscope. Check that the white luminance signal level is 640
±
10mVp-p and that
the gray luminance signal level (on the gray scale background) to 290
±
10mVp-p.
