Notes on Use
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 to +40 °C (41 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
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 ms.
• 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
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 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)
Error Messages
When an error is detected in the CCU or the camera, the
ALARM indicator turns on and an error message is displayed
on the CCU.
Return Signal Combinations
The return signals are grouped into the following 16
combinations. The number of the return signal (RET 1 to 4) on
the RETURN INPUT connectors is set on the <RETURN
FORMAT> page in the SYSTEM OPERATION menu.
Cable (for example) Max. distance Min. distance
Fujikura 8.5 mm dia. 600 m (1969 ft.) 50 m (164 ft.)
Fujikura 14.5 mm dia. 1200 m (3937 ft.) 100 m (328 ft.)
Belden 9232 13.2 mm dia. 850 m (2789 ft.) 75 m (246 ft.)
