JVC LST0420-001B manual WHT.BAL. ATW/MANUAL selection switch, BLC Backlight compensation switch

4.[WHT.BAL.] ATW/MANUAL selection switch.

For selecting whether to adjust the white balance automatically or manually.

When the setting is changed from manual to ATW, the setting values in the manual mode will be reset. The camera switches to the same mode as with pressing the [RESET] button.

(Default setting: ATW)

NOTE:

●The white balance of this camera is preset to use under sunlight or halogen lamps, and may not be properly adjusted when used under artificial lights such as fluorescent lights.

5.[BLC] Backlight compensation switch.

When the object is placed against the light, setting this to AONB increases the iris aperture by 1 stop and the object will appear clearer. (Default setting: OFF)

6.[DAY/NIGHT] Easy Day & Night switch.

To capture a subject with continually changing brightness (day/night), set this switch to AONB. The camera automatically captures the image in color when the subject is bright, and in black and white mode when it is dark. (Default setting: OFF)

NOTE:

●When this item is set to AONB, the AGC feature will automatically be set to AONB regardless of the [AGC] Switch 1 setting.

●The Easy DAY & NIGHT feature on this camera uses a sensitized black and white mode unlike other black and white surveillance cameras that use infra-red lighting.

●Sensitivity increases in the case of black- and-white images. The screen may therefore appear rougher and white spots may increase.

7.[RESERVED]

Not used. Ensure to set this to AOFFB before using the camera.

(Default setting: OFF)

8.[RESET/SPOT] RESET/SPOT CORRECTION selection switch.

RESET:

The [RESET/SPOT] button is used as a [RESET] button.

SPOT:

D [IRIS LEVEL] Iris level adjustment

For adjusting the level of the automatic aperture control lens. This adjustment only needs to be made when required. Use this to accommodate particular shooting conditions. To darken image: Counterclockwise (L side) To brighten image: Clockwise (H side)

NOTE:

Prior to adjusting the aperture level, ensure to set the [AGC] Switch 1 of the function selection switch C to AOFFB. Otherwise, when the level is turned too far toward L, the AGC function activates increasing sensitivity and the picture may look uneven.

E [FOCUS ADJUST] focus adjustment button

Use this to adjust the lens focus.

Upon pressing, the lens aperture will open up for about 30 seconds such that the depth of field becomes shallower, thus enabling focus to be easily adjusted. (A pg. 24)

NOTE:

The electronic shutter functions automatically upon pressing the focus adjustment button and the screen may flicker. However, this is not a malfunction.
