Auto electronic shutter
This is normally set to off at the factory.
If using a board lens (type B or C), the auto electronic shutter can be supplied from the factory at the on
setting. Since changing the setting is somewhat troublesome (requires tools and technical skill for
working with miniature parts) whenever possible, specify desired on or off setting at time of order.
Also note that certain types of lighting (e.g., fluorescent or mercury vapor) may cause flicker to appear on
the monitor screen due to effects of power line frequency.
