This function switches the condition of pictures from colour to
black and white in low light conditions.

Colour picture reverts to black-and-white pic-

ture when an external day/night switching signal is
received (refer to Day/Night connections).

When using this unit with infrared rays or lighting of

which colour temperature is 3 000 K or less, select this
mode without fail, and short-circuit the Day/Night input
terminals if you select the black-and-white picture.
(The AUTO mode may cause hunting.)

The camera selects black-and-white mode if the pic-

ture is dark, or colour mode if the picture is bright
enough.

• When using this unit with a video servo control lens, you

may not switch from the black-and-white mode to the
colour mode depending on lens iris.
In such a case, operate the lens adjuster to open the
aperture.

• This function may not be activated automatically when a

backlight or a strong light source causes excessive con-
trast in the picture. In such cases, use the Day/Night
input terminals.
