The electronic iris is suitable for normal indoor use. When switch 1 (IRIS) is set to the up (EI) position, do not use an auto-iris lens.

If used under fluorescent light, the image may flicker. In such a case, change to incandescent lighting or set switch 1 (IRIS) to the down (AI) position and use an auto-iris lens.

When shooting bright subjects, pay attention to the light angle in order to avoid or minimize the smear effect.

If conditions are outside the electronic iris operation range or more than the maximum illumination, the CCD will be saturated. In that case, use the auto iris lens.

Aperture (outline compensation) 2

If object outlines appear too strongly, set to “NORM”.

SHRP	Emphasizes object outlines.
NORM	Normal setting

Gain control (AGC) 3

For adjusting the sensitivity of the camera. Use this setting for shooting in dark environments.

HI	Increased sensitivity allows shots to be taken in dark
	environments.
NORM	Normal setting

White balance (color compensation) 6 9 10

MANU	Lets you fine-tune the white balance manually.
	WB	• R (Red) dial			: Turn clockwise to augment screen red.

		• B (Blue) dial			: Turn clockwise to augment screen blue.
				10
ATW	Compensation is performed automatically.

Sync setting 7

Vertical sync disturbance may occur when a selector is used to switch between multiple cameras connected to one monitor. To prevent vertical sync disturbance, set to “LL.”

LL (external sync)	Adjust PHASE dial to eliminate sync disturbance.
INT (internal sync)	Internal Sync

LL (Line-Lock): Synchronizes the unit with power frequency.

If image disturbance doesn’t disappear after adjusting the PHASE dial on the second and subsequent cameras, adjust the PHASE dial on the first camera. If the problem persists, check that all the devices have been connected with the correct power cable polarity.

The HI setting causes noise generation and a grainy image.

Backlight compensation 4 5

This camera has two different backlight compensation functions: Normally backlight compensation switch 4 and 5 are set to the down (OFF)

position. Change the backlight compensation switch settings depending on the conditions.

Multi-spot metering

Color/black and white switch setting 8

This switch lets you select the timing of the automatic switching of the optical filter to color image or black and white image, according to the subject brightness.

H	For a brighter setting than L
L	Standard setting

When the power is turned off and then on, switching will restart from color.

A sound of the optical filter may be heard when the color image or black and white image is switched. Also, the image will be distorted (black lines

Supported coaxial cables

You can use any of the following coaxial cables:

RG-59U (3C-2V) Length: About 250 m max.

RG-6U (5C-2V) Length: About 500 m max.

RG-11U (7C-2V) Length: About 600 m max.

When using an RG-59U (3C-2V) cable, do not use it on piping or air wiring.

Select the cable according to the distance between the devices you wish to connect.

If you use a cable other than the types above, the image or sync signal will be attenuated and will not be transmitted correctly.

Making connections

The maximum length of cable for the CONTROL terminal is 400 m (AWG24).

During optical filter switching, even if the manual switching operation is complete, you cannot determine if the image is color or black and white. Manual switching will have to be performed one more time.

FLANGE-BACK ADJUSTMENT

If the pick-up surface is not correctly positioned with relation to the lens focal point, the picture will be out of focus (in particular when using auto-iris power zoom lenses, sold separately). If that is the case, adjust the flange- back position as described below.

1 Using a + screwdriver, loosen the flange-back lock screw (M2:+).

If the background of the object is

may appear on the screen). This is normal and does not indicate a problem.

When using infrared lighting, and if there is a strong reflection on the subject, the optical filter may switch from black and white to color mode. The focus setting may be different in color and black and white mode. Please check and adjust the focus setting in both modes.

Iris dial (lens iris) 11

If the entire image is too dark or too bright, adjust the LEVEL dial ( 11 ).

L (Low)	Closes the lens iris, making the entire image darker.
H (High)	Opens the lens iris, making the entire image brighter.

1Connect the camera and peripheral equipment.

2Connect the power cable. <When using a 24 V AC adapter>

Connect 3 wire grounded cable (use 18AWG+) to the ground (GND) terminal as shown in Figure 1.

<When using a 12 V DC adapter> Connect the cable as shown in Figure 2.

When connecting the power cable to the camera, check that the polarity is correct.

To prevent a fire hazard use any UL listed wire rated VW-1 for the 24 V AC cable input terminal.

3Insert the power adapter plug into the wall outlet. The power indicator (POWER) lights.

Color/black and white setting

Connect each pin of the CONTROL terminal as indicated below, to set the image to color or black and white manually. You can adjust the image by remote control.

Color image setting

Connect the C (color) and the G (ground) pins.

Black and white setting

Connect the B (black and white) and the G (ground) pins.

2	Set the zoom lens to the maximum telephoto position and set the
3	focus using the focus ring on the lens.
	Set the zoom lens to the maximum wide angle position and set the
4	focus using the flange-back adjustment lever.
	Repeat steps 2 and 3, until the image stays in focus when
	changing from a telephoto shot to a wide angle shot.
	When the setting is complete, tighten the flange-back lock screw.

When the flange-back lock screw is completely tightened it will protrude slightly as shown in the illustration (Fig. A).

Do not tighten the screw further.

CAMERA ADJUSTMENTS/SETTINGS

The camera comes pre-adjusted and ready to install at time of factory shipment, but you may want to make adjustments or settings to adapt to the operating conditions or installation environment.

If you have trouble adjusting the camera, contact your place of purchase or a Sanyo Authorized Service Center.

Iris setting 1

Change Iris setting when using either lens below.

EI	When using a manual or fixed iris lens and the electronic iris
(for indoor use)	function is on.
	* Set the lens aperture to the shortest F stop.
AI	When using an auto-iris lens.
