Operating Instructions
Operating precautions
Shoot under the proper lighting conditions.
To produce pictures with eye-pleasing colors, shoot under
the proper lighting conditions.
The pictures may not appear with their proper colors when
shooting under fluorescent lights.
Select the proper lighting as required.
To ensure a stable performance in the long term
Using the unit for prolonged periods in locations where the
temperature and humidity levels are high will cause its parts
to deteriorate, resulting in a reduction of its service life.
(Recommended temperature: Max. 35 °C [95 °F])
Ensure that a cooling unit or heating unit will not blow any air
directly toward the installation location.
Image persistence on the MOS sensor color filters
If parts of the MOS sensor are exposed continuously to
spotlights or other bright lights, the color filters inside the
MOS sensor will deteriorate, and the parts concerned may
become discolored. The discoloration may be noticeable
when the direction of fixed monitoring is changed.
Do not point the camera at strong
lights.
When parts of the MOS sensor are
exposed to spotlights or other strong
lights, blooming (a phenomenon where
the edges of strong lights become
blurred) may occur.

Concerning the color reproduction of MOS sensors
Depending on the color tones of the subjects, the color
reproduction may deteriorate: This is normal and not
indicative of any trouble.
What happens with high-brightness subjects
Flare may occur if an extremely bright light source is pointed
at the lens. In a case like this, change the angle or take some
other remedial action.
When using the automatic functions
●
If “Full Auto” has been selected as the setting for Scene
on the camera menu, for example, all the auto settings
will be turned on, and manual operations will no longer be
possible for some of the items.
●
When using the ATW (auto tracking white adjustment)
function under fluorescent lights, the white balance may
vary.
●
In some situations, it may be hard to focus at the auto
setting. In cases like this, select the manual setting, and
focus manually.
●
The appropriate brightness may not be obtained when
shooting bright objects using the auto settings for the gain
and iris.
In cases like this, set the shutter speed to manual, and
adjust.
Zooming and focusing
When the focus is set manually, out-of-focusing may occur
during zooming.
After zooming, if necessary, either adjust the focus or set the
focus to auto.
When using the focus at the manual setting, proceed with
zooming after setting the focus position at the Tele end where
the focusing accuracy is higher.
(However, if the distance from the unit to the subject is less
than 1.0 meter [3.28 ft], the subject may shift out of focus at
the Wide end.)
If zooming is performed to the Tele end after having adjusted
the focus at the Wide end, out-of-focusing may occur.
Concerning the zoom position when the power is turned
on
When the unit is turned on, the zoom, focus, and iris return
to their positions from before the unit entered standby mode.
(This happens for the focus and iris when they were set
manually.)
The operation will be performed with the [Preset Scope]
settings applied in such cases.
However, this position may not be restored if, for instance,
the power cable was disconnected during operation.
Operating temperature range
Avoid using the unit in cold locations where the temperature
drops below 0 °C (32 °F) or hot locations where the
temperature rises above 40 °C (104 °F) since these
temperatures downgrade the picture quality and adversely
affect the internal parts.
Concerning the HDMI interface standard
The unit has been certified as HDMI-compatible, but on rare
occasions images may not be displayed depending on the
HDMI device which has been connected to the unit.
