JVC TK-C750 プリント

Configure the camera according to the Connection instructions above, turn it on, display an image
on the monitor, and check the image. The camera has been factory-set for optimum operation, but
it may need further adjustment according to the prevailing conditions and to the lenses to be used.
If the image does not appear natural, adjust as follows:
• LEVEL adjustment

• If the sensitivity adjustment LEVEL is turned too far to L, the sensitivity will increase due to the

AGC function of the camera, making the image look grainy.

• In order to adjust the Iris LEVEL of this camera, first, set it to H (iris fully open) and then adjust

the LEVEL slowly to its optimum position.

Back focus has been optimally adjusted at the factory for CS-mount lenses, but it may
need re-adjustment if the mount is changed for C-mount lenses. If required, adjust as
follows:

• With a fixed-focus lens
If the focus can not be adjusted correctly by rotating the lens focus ring, adjust the back focus as
follows.
1. Loosen the back focus locking screw by turning it anti-clockwise (

) with a screwdriver.

2. Point the camera at a test pattern.
3. Turn the lens focus ring to ∞.
4. Turn the back focus adjustment ring to find optimum focus.
5. Tighten the back focus locking screw by turning it clockwise (

).

• With a zoom lens
If the lens does not track (loses focus) at any point in the zoom range, adjust as follows:
1. Loosen the back focus locking screw by turning it anti-clockwise (

) with a screwdriver.

2. Point the camera at a comparatively dark scene with thin lines.
3. Set the lens to the maximum telephoto position, and adjust the lens focus.
4. Set the lens to the maximum wide-angle position, and turn the back focus ring to adjust the

focus.
(Repeat steps 2 and 3 two or three times.)

5. Tighten the back focus locking screw by turning it clockwise (

).

To set the camera in LL mode for synchronization with the power supply frequency, do the following :
1. Turn switch 

w to “LL”;

2. Press the + or – button 

q to  make the phase variable.

Adjust with the button 

q so that the vertical phase of the camera matches the vertical phase of

another camera (or system) with a multi-channel oscilloscope.
To reset the setting, press the + and – buttons 

q simultaneously.

E type:  50Hz power region only

White balance can be adjusted within the scope of 2300K to 10000K color temperature. When
switch 

e is at ATW (Auto-Tracking White Balance), the white balance is automatically adjusted

according to the color temperature of the ambient illumination.
When the white balance is set to AWB (Auto White Balance), press and hold the SET button 

y for

2 seconds to adjust or readjust the white balance. Once the white balance is adjusted, the setting
will not track changes in the color temperature of the ambient illumination.

The switch 

r helps to rectify the situation where a subject appears dark because of backlighting.

Set this switch to ON for strongly backlit subjects.

Turning this switch 

t “ON” when a lens with a manual iris diaphragm is used enables the auto-

matic adjustment of image brightness. In this case the shutter speed changes according to the
brightness of the subject.

Hunting may occur at a certain object brightness due to the mechanism of the AES circuit, but
this is not a fault.
