3.1.2 (c) Internal Slow Reset Mode
The speed control ranges from 1/120 to 1/950 sec. The video signal starts with internal V. Select a dial
switch setting from "1" to "4". With the internal slow reset mode selected, the camera operates the reset
and shutter in the same way as the external double pulse control mode. When the external VINIT pulse
is applied, internal VINIT is latched to Hd and the second internal VINIT signal is delayed to set up the
shutter speed period. The shutter speed is controlled by the dial switch from "5" to "8". Video output
timing starts right after the second internal VINIT.
