Operating Considerations - Hitachi KP-FD30 Operation Manual

Operating considerations

Power supply
Be sure to use the power source specified in the Major
Specifications.
・Before plugging or unplugging a connector, be sure
to turn off power.
To plug or unplug a connector, be sure to hold the
connector section.
・Note that it will take several seconds until a picture is
displayed on the monitor after power on.
Handling
・Do not attempt to remove cover.
・When installing or removing a lens, be sure to use
care that water or dust does not enter the inside of.
the camera.
Installing and storage
Avoid installing or storing the camera in the following
environments.
・Environments exposed to direct sunlight, rain or snow
・Environments where combustible or corrosive gas
exists
・Excessively warm or cold environment (Operating
ambient temperature: -10 to 50℃)
・Humid or dusty environment
・Place subjected to excessive vibration or shock
・Environment exposed to strong electric or magnetic field
Phenomena inherent to CCD imaging device
Following are the phenomena inherent to a CCD imaging device, and not defects
1) Smear and blooming
When strong light (lamp, fluorescent lamp, reflected
light, etc.) is shot, pale bands are displayed vertically
above and below the light.
In this case, change the angle of the camera so that
such strong light does not enter the camera through
the lens.
2) Fixed pattern noise
When the camera is operated in a high temperature,
fixed pattern noise may appear on the entire screen.
・Do not aim the camera lens at the sun.
・Do not shoot strong light or a scene including strong light.
When such a scene is shot, vertical trailings will appear.
However, this is not due to failure.
In case strong Tight enters the camera through the lens,
partial deterioration in picture quality will result.
To obtain stable performance for long time
When the camera is used continuously for long time
under high ambient temperature, the inside electrical
parts become deteriorated, resulting in shortening its life.
To use the camera continuously for long time, the
highest temperature must be below 40℃.
Cleaning
・Use a blower or a lens brush to remove dusts on the
lens or the optical filter.
・Wipe dirts on the case off with dry soft cloth. lf dirks
are hardened, wipe them off with cloth moistened
with neutral detergent liquid; wipe the cover with dry cloth.
・Do not use benzine,thinner,alcohol,liquid cleaner or
spray-type cleaner.
・In event dust or other debris is lodged between the CCD
and optical filter, consult dealer for cleaning by an optical
technician.
3) Moire
When fine patterns are shot, moire may be displayed.
4) Burning
When excessively intense light comes to the
CCD for a long time, the spectral filter in the
CCD pixel may be deteriorated, and the colour of
the corresponding portion may change.
Avoid using the camera under such condition.
