PRODUCT SAFETY NOTICE

Many electrical and mechanical parts have special safety-related characteristics. These are often not evident from visual
inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for a
higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this
Service Manual. Electrical components having such features are identified by marking with a on the schematics and
the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety
characteristics as the HITACHI recommended replacement one, shown in the parts list in this Service Manual, may create
shock, fire, or other hazards. Product safety is continuously under review and new instructions are issued from time to time.
For the latest information, always consult the current HITACHI Service Manual. A subscription to, or additional copies for,
HITACHI Service Manual may be obtained at a nominal charge from HITACHI SALES CORPORATION.

2. Connecting to a VTR

Use a coaxial cable to connect the camera’s VIDEO OUT jack to the VTR’s VIDEO IN
jack.
Since the camera’s internal sync signal is 2:1 interlaced, a good slow-motion picture
or still picture can be played by the VTR.
Also read the VTR’s instruction manual for connecting to a VTR.

monitor’s VIDEO IN jack using a coaxial cable. Set the 75 ON-OFF switch on the
monitor to ON.

VK-C307E/VK-C317E

VIDEO OUT

If you use two or more colour video monitors, connect the camera’s VIDEO OUT jack
of the first monitor’s VIDEO IN jack using a coaxial cable, connect the first monitor’s
VIDEO OUT jack to the 2nd monitor’s VIDEO IN jack, then connect in this way to the
last monitor. Set the 75 ON-OFF switches on each monitor to OFF apart from the
last monitor which must be set to ON. Use coaxial cables for all connections.

2.2 Notes

1) All adjustments are performed using the adjustment program and personal computer (PC). The adjustment program is
subject to change without notice for improvements in functions and operability, and the actual instructions on PC screen
may be different from those in this manual: If so, follow the instructions on PC screen to proceed with adjustment.

2) The adjustment program will not operate normally unless the video camera, PC and test equipment/jigs are all turned on.

3) Be sure to connect the video output of video camera to a color video monitor (terminate the video output with 75 ohm:
If the video output is not connected to the monitor (and if it is not terminated with 75 ohm), the output video signal level
cannot be measured correctly.

4) Use light box that does not flicker and whose color temperature is controlled, for adjustment. If an inappropriate light box is
used, precise adjustment will not be possible, and the adjustment program will not operate normally.

5) Take care with the following when pointing the video camera at a chart (light box):

Focus the chart correctly.
Set the chart (light box) 30 - 50 cm away from the lens surface, and avoid any effects from surrounding light (except for
a case where some designation is given).
Aim at the chart and let chart fill the screen (video period). (Except for a case where some designation is given.)

2.4 Setting Test Equipment

1) Set the switches, knobs and each mode of oscilloscope as follows for adjustment: (except for a case where some
designation is given)

Probe: 10:1
TIME/DIV: 10 or 20 µs
VOLTS/DIV: Will vary depending on the measurement object
Synchronization: Internal sync
