Be sure to check when dissemble and repair the lens-barrel
(1) Check the performance
Repeat the following performance several times: After tuning the power switch ON and driving the zoom,
turn it OFF.
Conrm that there is no abnormal operation by repeating to check the release performance several times.
(2) Check the resolution
By photographying the high-denition resolution chart (J63079), conrm that the TV lines are within the standard.
Standard for the TV lines: more than 1100 TV lines in the Center; more than 750 TVs in the 4 corners.
(ref.：The resolution is based on the unit of TV lines that are black-and-white strips distinguished in the TV screen.)
(a) The camera is set as follows to take photos: Shooting-mode: Auto, Image quality mode: FINE, Image
size: 2272, Flash mode: Flash cancel
(b) The uneven pattern in luminance of the chart does not affect, but photograph with the luminance
(ISO100, 1/15-1/250) by which the aperture is open.
(c) Check the zoom position in the order of WIDE, MIDDLE (press the button 6 times starting from WIDE)
and TELE.
The object distance is WIDE: approx.65cm, MIDDLE: approx.115cm, TELE: approx.185cm. Set the
chart fully screened in the LCD of the camera, and x on a tripod.
(d) Open the photographed image by Photoshop, and conrm it by the magnied display, e.g. 100%, etc.
(e) Regarding the resolution of the frame center and the 4 corners, check if it is clear in black and white in
the position circled in red as shown in the below.
In case either (1) or (2) of the above fails, it is necessary to replace the lens-barrel group unit with the new one.

5. Installing USB drive
Install the USB drive with camera or connection kit for PC.
6. Pattern box
Turn on the switch and wait for 30 minutes for aging to take place before using Color Pure. It is used after
adjusting the chroma meter (VJ8-0192) adjust color temperature to 3100 ± 20 K and luminosity to
900 ± 20 cd/m2. Be careful of handling the lump and its circumference are high temperature during use and
after power off for a while.
・Procedure for correcting Pattern Box
Note: Be sure to perform the aging correction.
1) Measure the center of screen with the Color Meter (J63081).
2) Adjust the pattern box so that the color temperature would be 3100±20K by using "VR for adjustment of
the color temperature".
3) Measure the center of screen with the Luminance Meter BM-300 (J63068).
4) Adjust the pattern box so that the brightness would be 900±20cd/  by using "Knob forbrightness
adjustment".
5) Repeat process 1) to 4) until the color temperature would be 3100±20k and brightness
would be 900±20cd/ .
