On the rear panel mode switch SW3, set switches 1 and 2 to ON. At this point there will be no image output. When an external VI command is input, expo- sure will occur for the period of the command. This mode is only for non-inter- lace. The image quality may be lower due to timed exposures; use accordingly. Figure 4±4 shows the VI mode shutter timing.
