SENS-UP switch

To increase the sensitivity, set this switch to ON position.

DAY/NIGHT switch

When the DAY/NIGHT function is used, this switch is turned ON. (See P. 9.)

Camera output terminal

This is an image output terminal. When the camera direction, the field angle or the focal point is

adjusted, a monitor TV or other type display is connected to this terminal.

When a monitor TV is connected to this terminal, remove the 2P connector beforehand.

Level adjusting volume

This volume is used to adjust the brightness of the image. If the lens iris is not appropriate,

adjust the iris with this level adjusting volume.

Vertical sync. phase adjustment potentiometer

Vertical sync. phase adjusting potentiometer is set at the position fully that the delay time of

vertical sync. phase against the phase of power frequency is shortest, when shipped from the

factory.

Select this up ( ) and down ( ) button will make the delay time of vertical sync. phase

against the phase of power frequency longer.

Use the function control potentiometer if the picture image on a monitor TV may flow

when using the camera in combination with other camera(s) controlled by the Line-Lock

synchronization.

In this case, get a proper image by shifting the phase of vertical sync. signal of the camera

against that of the other. If a proper image cannot be obtained even after this adjustment, reset

the potentiometer to its original position, and use the function control potentiometer of the

other camera to shift the phase of vertical sync. signal of other camera.

Caution:

Before making adjustment, make sure that cameras have their power supplies

connected with the same polarity. (not 180 apart)
