(3. 1) H (horizontal) phase adjustment
Observe the external sync signal and the video signal output
waveform of the unit with a dual trace oscilloscope, and ad-
just H phase so that the H phases match.
( 4 ) Changing HD/VD input/output
(1) Put off 6 screws both on flank/top of camera chassis.
(2) Change internal switch SJ01(HD/VD).

The shutter speed can be set by the horizontal scanning period (1H) or by the frame.
( 1 ) Setting by 1H
1H/796H to 795H/796H (1H/387H to 386H/387H when partial scanning at 60fps, 1H/258H to 257H/258H when
partial scanning at 90fps) stands for the setting by the 1H and the shutter speed can be set by the 1H (43.05
µs).
( 2 ) Setting by the frame
2FRM to 512FRM stand for the setting (long period exposure) by the frame.
The video signal stored during the frame period set is output as 1 frame video image at a frame interval
specified.
