Fujitsu CG-311 SERIES instruction manual DAY/NIGHT Mode D/N, Flickerless FL

DAY/NIGHT MODE (D/N)

There are two modes of AUTO and HOLD in this camera at Day/Night mode.

The Day/Night operation works automatically according to the brightness of subject in AUTO mode.

When you prefer to maintain current state, HOLD mode may be used.

At #7 switch of DIP Switch

Left side : AUTO

Right side : HOLD

(Factory setup is AUTO mode.)

CAUTION:

When using this camera with IR light or light- ing where the color temperature is 3000 k or less, this camera shifts automatically to night mode.

Under unfavorable conditions (strength or angle of illumination) it can happen that hunt- ing occurs.

The CG-311 has a special circuit to prevent such kind of hunting problems.

If the camera detects a hunting condition, the night mode is maintained for 30 minutes. Every 30 minutes the camera checks automati- cally whether the condition which caused hunt- ing still exists and maintains if so for further 30 minutes.

To avoid this operation you have to adjust the strength or the angle of the illumination.

FLICKERLESS (FL)

CAUTION:

This function is used under fluorescent light on the power supply area with different frequency from the camera scanning frequency.

Set the FL switch (#8 switch of DIP Switch) to “OFF”, otherwise the flicker may occur. (Factory setup is FL OFF.)
