Precautions
Note on laser beams
Laser beams may damage the CCDs. If you shoot a scene that
includes a laser beam, be careful not to let a laser beam
become directed into the lens of the camera.
Do not subject to severe shocks
Damage to the case or internal components may result.
When finished using
Set the power switch to OFF.
Operation and storage environment
Store in a level place with air conditioning.
If the unit gets wet, make sure it is completely dry before
storage.
Avoid use or storage in the following places:
• Extremely hot or cold places
• Places with high humidity
• Places with strong vibration
• Near strong magnetic fields
• In places where it receives much direct sunlight, or near
heating equipment
Condensation
If you move the camera from a very cold place to a warm
place, or use it in a damp location, condensation may form on
the lens or inside the camera.
The camera has no built-in condensation indicator. If you find
condensation on the body or lens, switch the camera off and
wait for the condensation to disappear for about one hour.
Phenomena specific to CCD image sensors
The following phenomena that may appear in images are
specific to CCD (Charge Coupled Device) image sensors.
They do not indicate malfunctions.
White flecks
Although the CCD image sensors are produced with high-
precision technologies, fine white flecks may be generated on
the screen in rare cases, caused by cosmic rays.
This is related to the principle of CCD image sensors and is
not a malfunction.
The white flecks especially tend to be seen
• when operating at a high environmental temperature
• when you have raised the master gain (sensitivity)
This product has a compensation function and the problem
may be alleviated by automatic black balance adjustment
.
Smear
When an extremely bright object, such as a strong spotlight or
flashlight, is being shot, vertical tails may be produced on the
screen, or the image may be distorted.
Aliasing
When fine patterns, stripes, or lines are shot, they may appear
jagged or flicker.
About digital triax transmission
A powerful error-correction function is incorporated for the
transmission between the camera and CCU. However, if an
error occurs on long-distance transmission because of
external noise or for some other reason, the compensation by
interpolation that partially uses the previous picture may
operate.
In digital triax transmission, the following video delay in
transmission may occur:
• The video delay in transmission between the camera and
the CCU is approx. 9 msec to 12 msec.
• A delay of about 1 frame occurs on the viewfinder display if
a camera image is sent back from the CCU to the camera as
a return signal.
• The prompter video will delay approx. 5 frames in the
standard mode. (For the prompter video, either the standard
mode or the low-delay mode using simplified images can be
selected on the CCU).
• An appropriate delay is applied to the MIC 1 and 2 audio
signals from the CCU according to the video delay.
• It takes a certain time until the video signal transmitted
between the camera and the CCU becomes stable after
power is applied. This is not a malfunction.
About the distances of triax transmission (when an
HSCU-300 is connected)
The maximum and minimum transmission distances allowed
for triax cable connection are shown in the table below. The
distances may vary according to the conditions, such as the
total power requirements (including the power supply to the
camera from the CCU) and cable degradation.
Allowable transmission range when using triax cables with the
following characteristics:
Attenuation: 3.8 dB to 68.4 dB at 100 MHz (including the
loss at connectors)
1) If the transmission distance exceeds approximately 7/9 of the
maximum transmission distance, the teleprompter transmitted
image quality starts to deteriorate.
2) The maximum distance will be 650 m (2133 ft) when the total power
for the lens, viewfinder and utility outputs is between 100 and
120 W.
About the distances of triax transmission (when an
HXCU-100 is connected)
The maximum and minimum transmission distances allowed
for triax cable connection are shown in the table below. The
distances may vary according to the conditions, such as cable
degradation.
Allowable transmission range when using triax cables with the
following characteristics:
Attenuation: 3.8 dB to 45.6 dB at 100 MHz (including the
loss at connectors)
