Adjustment procedure 1
(When a color differential meter is used)
1. First adjust the [MID-1] tone [G:].
2. Select adjustment point [No.2][G:].
When the background is not [G] monochrome,
press the [ENTER] key on the remote control to
switch to solid [G] monochrome.
3. Measure the illumination at adjustment points
No. 2, No.3, No.10 and No.11.
The values should be:
No.2 = Y2 [lx] No.10 = Y10 [lx]
No.3 = Y3 [lx] No.11 = Y11 [lx]
4. No.2 and No.3 adjustment points have the
average of Y2 and Y3.
Y2 = ( Y2 + Y3 ) / 2 ± 2 [%]
Y3 = ( Y2 + Y3 ) / 2 ± 2 [%]
5. No.10 and No.11 adjustment points have the
average of Y10 and Y11.
Y10 = ( Y10 + Y11 ) / 2 ± 2 [%]
Y11 = ( Y10 + Y11 ) / 2 ± 2 [%]
6. Then adjust the [MID-1] tone [R] and [B].
When the background is [G] monochrome,
press the [ENTER] key on the remote control to
switch to solid white.
7. Measure the color coordinates of adjustment
point [No.1] and make a note of them.
Assume that they are x = x1, y = y1.
Note: When the CL-100 color and color
difference meter is used, the [ ¨](delta)
mode is convenient. When adjustment
point [No.1] color coordinate has been
selected, set the slide switch on the side
to [¨](delta) while holding down the [F]
button on the front panel. The
measurement shown after this displays
the deviation from measurement point 1.
8. Measure the color coordinates of measurement
point [No.2] and adjust [No.2][R:] and [B:] so
that the coordinates are as follows.
x = x1 ± 0.005 , y = y1 ± 0.010
9. Similarly, measure adjustment points [No.3] to
[No.17] and adjust their color coordinates
starting in order from the small number points.
This completes adjustments required for
[MID-1].
Note: Since excessive correction may lead to a
correction data overview during internal
calculations, use the following values for
reference.
[No.2] to [No.5] ± 40 or less
[No.6] to [No.9] ± 50 or less
[No.10] to [No.13] ± 70 or less
[No.14] to [No.17] ± 120 or less
10.Then adjust the [MIN] tone [G] so that the
adjustment values are two times as much as
MID-1] tone [G] values.
This completes [G] color adjustments.
11.Then adjust [MIN] tone [R] and [B].
Select [No.2] [B:] and press the [ENTER] key
on the Remote control transmitter to change to
solid white.
12.Measure the color coordinates of adjustment
point [No.1] and make a note of them.
Assume that they are x = x1, y = y1.
13.Now measure the color coordinates of
measurement point [No.2] and adjust [No.2][R:]
and [B:] so that the coordinates are as follows.
x = x1 ± 0.005 , y = y1 ± 0.010 (Target)
x = x1 ± 0.020 , y = y1 ± 0.040
14.Similarly, measure adjustment points [No.3] to
[No.17] and adjust their color coordinates
starting in order from the small number points.
This completes [MIN] tone adjustments.
15.Now make similar adjustments for [MID-2] tone.
(Adjust [MID-2] tone [G] so that the adjustment
data set half as many as [MID-1] tone [G].)
16.Now make similar adjustments for [MID-3],
[MID-5], [MAX] tones. (It is not necessary to
adjust the [G] data in these tones.)
17. After completing the step 16, set the value of
the [MID-4] tone [R]: [No.2] to the mean of the
values of the [R]: [No.2] in the [MID-3] and
[MID-4] tones.
18. Set all the values for the [No.2] to [No.17] of
the [MID-4] tone [R] and [B] in the same way as
the step 17.
19. Finally, set the data of the [MID-6] tone [R] and
[B] using the values of the [MID-5] and [MAX]
tones in the same way as the [MID-4] tone [R]
and [B] adjustments in the step 17 and 18.

CP-A100 / ED-A100 / ED-A110 (A1DN)
Adjustment procedure 2
(visual inspection)
1. First adjust [MIN] tone [G:].
2. Select [No.2] [G:].
If the background is [G] monochrome, press the
[ENTER] key on the remote control to switch to
solid white.
3. View measurement point [No.2] and [No.3].
Lower the [G] color intensity only of the color
point whose [G] color is more intense than
measurement point [No.1].
4. View measurement point [No.10] and [No.11].
Lower the [G] color intensity only of the color
point whose [G] color is more intense than
measurement point [No.1], and raise the
intensity of the point whose color intensity is
lower than measurement point [No.1].
5. Now adjust the [MIN] tone for colors [R] and [B].
6. View measurement points [No.2], [No.3],
[No.10] and [No.11]. Adjust the [R] and [B] of
each measurement point so that they have the
same color as measurement point [No.1].
Adjustment technique:
First, adjust [B:] of the point whose color is to
be adjusted so that it approximates that of
[No.1]. If [R:] is low at this time, the image will
have cyan cast, in which case [R:] is increased.
On the other hand, if [R:] is excessive, the
image will have a magenta cast, in which case
[R:] is decreased.
Overall, a cyan cast makes it easy to see color
shading.
7. Next, view measurement points [No.4], [No.5],
[No.12], [No.13] and make similar adjustments.
8.
Then adjust measurement points [No.6], [No.7],
[No.8], [No.9], [No.14], [No.15], [No.16] and [No.17].
This completes the [MIN] tone adjustments.
9. Make similar adjustments for other tones,
except the [MID-4] and [MID-6] tones, as
described in steps 1 to 8 above.

4-10 Installation Suggestions for CP-A100/ ED-A100/ED-A110
• The suggested projection image size is from 60” to 100”. It is recommended to check if the focus
performance is acceptable for your needs when projecting at larger than 100”.
• It is strongly suggested to use the board-type screens with flat surface. Using the roll-type screens or any
screens with wavy or uneven surface may results in the image distortion.
• Allow enough time for projector setting whenever the projector is moved.- Adjust focus before
adjusting image position and projection angle. Changing focus may cause change of the image size.
• The projected image position and/or the focus may change during the warm-up (approx. 30 minutes after
the lamp is turned on) or when the ambient condition changes. Adjust the image position and/or focus if
necessary.
Following the instruction below when the projector is to be fixed on the ceiling or the wall.
[Note]
• Use only Hitachi-recommended installation boom.
• Adjustment may be required even when the projector is installed according to the distance and angle
suggested on the instruction.
• Note that the projection distance needs to be adjusted by boom length or position since the projector is
not equipped with optical zoom functionality.
• The aspect ratio on the projected image and/or the projected image size may change during the focus
adjustment.
• The projected image position and/or the focus may change during the warm-up (approx. 30 minutes after
the lamp is turned on.).
• The projected image size and/or its position may change due to the ambient condition, such as
temperature and/or humidity changes.
• The projected image position may change after the installation (allow about 1 week to stabilize).
Step 1
• Roughly adjust the focus to match the screen size after mounting the projector to the boom.
• Keep the projector running for more than 30 minutes after focus adjustment.
Step 2
• Adjust/Make the projected image size smaller than the actual screen size by keeping margins for all sides
of the screen as shown in the table below.
Step 3
• Adjust the focus if the focus changed after the adjustment of the projected image size and position.
• Go back to the Step 2 if the image size goes over the margins after the focus fine-tuning.
