5IRIS switch

When a DC driven type auto iris lens is used, set this switch to DC position. When a video

feedback type auto iris lens is used, set this switch to VIDEO position.

6ALC LEVEL

Adjust video output level, when IRIS switch is DC position.

7AES switch (Automatic Electronic Shutter)

With the AGC switch at ON position, AES are available.

By setting the AES switch, Automatic Electronic Shutter mode (1/60~1/10,000 sec) is available. Note: In electronic shutter mode;

*Sufficient brightness is required.

*The picture will flicker when shooting under the illumination produced by fluorescent lamp.

8Vertical sync. phase adjustment potentiometer

Vertical sync. phase adjusting potentiometer is set at the position fully counterclockwise that the delay time of vertical sync. phase against the phase of power frequency is shortest, when shipped from the factory.

Turning this potentiometer clockwise will make the delay time of vertical sync. Phase against the phase of power frequency longer.

Use the function control potentiometer 8 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 8 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)
