line frequency. When switching between 
multiple cameras using a switcher, selecting 
this mode and adjusting the vertical phase 
can reduce the monitor sync disturbances 
occur that when the camera image is

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)

● 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.

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)

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)

● 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.

Not used. Ensure to set this to 

AOFFB before 

using the camera.
(Default setting: OFF)

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)

● 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

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. (

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