Adjusting the angle of view, focus and
brightness
Upon determining the imaging direction, adjust
the angle of view, focus and brightness
accordingly.
Note:
● When adjusting the focus, make sure to cover
the dome cover over the lens. The dome
cover of this unit is thick. Therefore, if the
focus is not adjusted with the dome cover
covered, this may cause the lens to go out of
focus when the dome cover is mounted.
● When adjusting the focus, cover the dome
cover such that its center is perpendicular to
the light axis of the lens, and make sure that
the image is not distorted. (See illustration
below)
Adjusting the angle of view
Loosen the fastening screw for the zoom
adjustment ring and move the ring to the left/
right to adjust the image.
Adjusting the focus
Press the focus adjustment button. The iris will
be released for about 30 seconds. Loosen the
fastening screw for the focus adjustment ring
and move the ring to the left/right to align the
focus.
Memo:
● Set by repeating [Adjusting the angle of view]
and [Adjusting the focus] for 2 to 3 times.
After adjustment is completed, fasten by
tightening each of the fastening screws.
● The electronic shutter functions automatically
upon pressing the focus adjustment button
and the screen may flicker. However, this is
not a malfunction.
Adjusting the brightness
Usually, adjustment of the brightness is not
required. When this is necessary, adjust the iris
level accordingly.
To darken : Anti-clockwise direction (L
side)
To brighten : Clockwise direction (H side)
Memo:
● Do not perform iris level adjustment within 30
seconds after pressing the focus adjustment
button. (It cannot be adjusted correctly as the
electronic shutter mode is activated.)
● Before adjusting the iris level, set the [AGC]
switch of selection switch C to AOFFB. If
turning too much to L side when not set to
AOFFB, AGC feature will activate causing the
sensitivity increases and the picture quality
may appear grainy.
