Overview
This unit is a new-generation multi-format HD camera that
supports the 1080i format.
It uses a ne
[1920 (H) 1080 (V)] imaging device. This newly developed
CCD employs leading-edge processes and embodies a
fresh look taken at the on-chip lens and CCD structure
to improve the sensitivity, smear and dynamic range by
a significant margin over previous CCDs. Furthermore,
Panasonic’s horizontal single-line readout CCD and
high
shifting and a dramatic reduction in moire within the band.
Another salient feature is the newly developed digital signal
processor LSI chip which is mounted in the camera head
and supports 14-bit A/D conversion: This chip processes
the gamma, knee, detail, matrix and other process signals,
delivers the kind of multi-functionality, high quality and
high stability that digital technology alone can provide, and
improves the operating ease.
The 14-bit A/D converter is instrumental in creating a
stable wide dynamic circuit with a high signal-to-noise ratio
from the dark area all the way to the highlights. Using the
dynamic range stretch (DRS) function which adjusts the
gamma correction optimally in real time, both the dark areas
and light areas can now be reproduced with startling clarity.
w-generation 2/3-inch 2.2-megapixel IT-CCD
-precision signal processing combine to achieve pixel
With buildup applications in mind, the camera head
incorporates a chassis which features a low center of gravity
while at the same time it has a compact size and a low
profile and it offers outstanding operating ease. The range
of these b
connections, mounting of a large-size lens and the shared
use of the large-size lens and barrel lens has been greatly
extended.
The amount of heat generated by the camera has also been
slashed as a result of adopting a low-power-consumption
design for the new circuits and a heat-dissipation design for
the new chassis.

Precautions for use
DON’TS
Do not attempt to disassemble the camera or other units.
In order to prevent electric shock, do not remove screws
or covers. There are no user-serviceable parts inside.
Do not abuse the camera. Avoid striking, shaking, etc.
The camera contains sensitive components which could
be damaged by improper handling or storage.
Do not let the lens remain uncapped when the camera is
not use. If the lens is not installed, do not leave the lens
mount hole uncovered.
Do not touch the surf
Do not use strong of abrasive detergents when cleaning
the camera body.
Do not aim the camera toward the sun, no matter whether
it is turned on or not.
Do not expose the camera to rain or moisture, and do not
try to operate the equipment in wet conditions. Do not
operate the camera if it becomes wet.
Do not operate the camera outdoors during a lightning
storm.
ace of the lens or prism.
DO’S
Refer any servicing to qualified service personnel.
Handle the camer
Protect the precision made lens by placing the lens cap
over when the camera is not in use. If the lens is not
installed, protect the surface of the prism by placing the
body cap into the lens mount hole.
Use a mild blower or lens cleaning tissue designed for
coated lenses, to clean the surface of the lens or prism in
the event that it should become dirty.
Use a dry cloth to clean the camera if it is dirty. In case
the dirt is hard to remove, use mild detergent and wipe
gently.
Use caution when operating the camera in the vicinity
of spot lights or bright lights, as well as light reflecting
objects and surfaces.
Take immediate action if ever the camera should become
wet. Turn the power off and have the unit checked by an
authorized service facility.
F
ollow normal safety precaution to avoid personal injury.
a with care.
Do not use the camera in an extreme environment where
high temperatures or high humidity exist.
Do not leave the camera turned on when not in use.
Do not unnecessarily turn the camera power on and off
repeatedly.
Do not block the ventilation slots.
Do not cover the port otherwise block ventilation during
operation. Internal heat buildup can cause a fire.
Use the camera in an environment where the temperature
is within 14 °F to +113 °F (–10 °C to +45 °C), and the
relative humidity is less than 85 % (no condensation).
Always turn the power off when the camera is not going
to be used. Operate the camera only when there is
adequate ventilation.
Cooling fan
There is internally provided a cooling fan.
Since the cooling fan is a consumable part, replace it
after about 50,000 hours of operation.
