Notes on Use

If the unit is suddenly taken from a cold to a warm location, or
if ambient temperature suddenly rises, moisture may form on
the outer surface of the unit and/or inside of the unit. This is
known as condensation. If condensation occurs, turn off the
unit and wait until the condensation clears before operating the
unit. Operating the unit while condensation is present may
damage the unit.
The fan and battery are consumable parts that will need
periodic replacement.
When operating at room temperature, a normal replacement
cycle will be about 5 years.
However, this replacement cycle represents only a general
guideline and does not imply that the life expectancy of these
parts is guaranteed. For details on parts replacement, contact
your dealer.
The life expectancy of the electrolytic capacitor is about
5 years under normal operating temperatures and normal
usage (8 hours per day; 25 days per month). If usage exceeds
the above normal usage frequency, the life expectancy may be
reduced correspondingly.
Use and storage locations
Avoid using or storing the unit in the following places:
• Where it is subject to extremes of temperature (operating
temperature: 5 °C to 40 °C (41 °F to 104 °F)).
• Note that in summer the temperature in a car with the
windows closed can reach 50 °C (122 °F).
• Very damp or dusty places.
• Where rain is likely to reach the unit.
• Places subject to severe vibration.
• Near strong magnetic fields.
• Near transmitting stations generating strong radio waves.
Avoid violent impacts
Dropping the unit, or otherwise imparting a violent shock to it,
is likely to cause it to malfunction.
Do not cover with cloth
While the unit is in operation, do not cover it with a cloth or
other material. This can cause the temperature to rise, leading
to a malfunction.
After use
Set the POWER switch on the CCU to the OFF position.
Care
If the body or panels of the unit become dirty, wipe them with
a dry cloth. For severe dirt, use a soft cloth steeped in a small
amount of neutral detergent, then wipe dry. Do not use volatile
solvents such as alcohol or thinners, as these may damage
the finish.

Digital Triax Transmission (HSCU300R)

Digital transmission between camera and CCU with powerful
error correction function built-in. However, some errors, for
example errors due to external noise in long-distance
transmission, may be corrected by partial image interpolation
of images in frame store.
In digital triax transmission, the following video delay in
transmission may occur.
• The video delay in transmission between the camera and
the CCU is approximately 9 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.
• A delay of about 5 frames occurs on the teleprompter video
in standard mode (standard mode or low-latency 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 to match the video delay.
• A certain time is required for the video signal transmitted
between the camera and the CCU to stabilize after power is
applied. This is not a malfunction.
Triax transmission distances (when an
HSC300R/HSC-300 is connected)
The maximum and minimum transmission distances allowed
for triax cable connections 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 to 68.4 dB at 100 MHz (including the
connector loss)
Cable (for example) Max. distance
Fujikura 8.5-mm dia. 900 m (2953 ft)
Fujikura 14.5-mm dia. 1,800 m (5906 ft) 100 m (328 ft)
Belden 9232 13.2-mm dia. 1,300 m (4265 ft) 75 m (246 ft)
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 is 650 m (2133 ft) when the total power for
the lens, viewfinder and utility outputs is between 100 and 120 W.
Triax transmission distances (when an
HSC100R/HXC-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 to 45.6 dB at 100 MHz (including the
connector loss)
Cable (for example) Max. distance
Fujikura 8.5-mm dia. 600 m (1969 ft)
