10 CP-A / ED-A0 / ED-A (AB-0) Adjustment procedure (When a color differential meter is used). First adjust the [MID-] tone [G:].. Select adjustment point [No.][G:]. When the background is not [G] monochrome, press the [ENTER] key on the remote control to switch to solid [G] monochrome.. Measure the illumination at adjustment points No., No., No.0 and No.. The values should be: No. = Y [lx] No.0 = Y0 [lx] No. = Y [lx] No. = Y [lx]. No. and No. adjustment points have the average of Y and Y. Y = ( Y + Y ) / ± [%] Y = ( Y + Y ) / ± [%]. No.0 and No. adjustment points have the average of Y0 and Y. Y0 = ( Y0 + Y ) / ± [%] Y = ( Y0 + Y ) / ± [%] 6. Then adjust the [MID-] 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.] and make a note of them. Assume that they are x = x, y = y. Note: When the CL-00 color and color difference meter is used, the [ ](delta) mode is convenient. When adjustment point [No.] 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. 8. Measure the color coordinates of measurement point [No.] and adjust [No.][R:] and [B:] so that the coordinates are as follows. x = x ± 0.00, y = y ± Similarly, measure adjustment points [No.] to [No.7] and adjust their color coordinates starting in order from the small number points. This completes adjustments required for [MID-]. Note: Since excessive correction may lead to a correction data overview during internal calculations, use the following values for reference. [No.] to [No.] ± 0 or less [No.6] to [No.9] ± 0 or less [No.0] to [No.] ± 70 or less [No.] to [No.7] ± 0 or less 0. Then adjust the [MIN] tone [G] so that the adjustment values are two times as much as MID-] tone [G] values. This completes [G] color adjustments.. Then adjust [MIN] tone [R] and [B]. Select [No.] [B:] and press the [ENTER] key on the Remote control transmitter to change to solid white.. Measure the color coordinates of adjustment point [No.] and make a note of them. Assume that they are x = x, y = y.. Now measure the color coordinates of measurement point [No.] and adjust [No.][R:] and [B:] so that the coordinates are as follows. x = x ± 0.00, y = y ± 0.00 (Target) x = x ± 0.00, y = y ± Similarly, measure adjustment points [No.] to [No.7] and adjust their color coordinates starting in order from the small number points. This completes [MIN] tone adjustments.. Now make similar adjustments for [MID-] tone. (Adjust [MID-] tone [G] so that the adjustment data set half as many as [MID-] tone [G].) 6. Now make similar adjustments for [MID-], [MID-], [MAX] tones. (It is not necessary to adjust the [G] data in these tones.) 7. After completing the step 6, set the value of the [MID-] tone [R]: [No.] to the mean of the values of the [R]: [No.] in the [MID-] and [MID-] tones. 8. Set all the values for the [No.] to [No.7] of the [MID-] tone [R] and [B] in the same way as the step Finally, set the data of the [MID-6] tone [R] and [B] using the values of the [MID-] and [MAX] tones in the same way as the [MID-] tone [R] and [B] adjustments in the step 7 and 8. 0

11 CP-A / ED-A0 / ED-A (AB-0) Adjustment procedure (visual inspection). First adjust [MIN] tone [G:].. Select [No.] [G:]. If the background is [G] monochrome, press the [ENTER] key on the remote control to switch to solid white.. View measurement point [No.] and [No.]. Lower the [G] color intensity only of the color point whose [G] color is more intense than measurement point [No.].. View measurement point [No.0] and [No.]. Lower the [G] color intensity only of the color point whose [G] color is more intense than measurement point [No.], and raise the intensity of the point whose color intensity is lower than measurement point [No.].. Now adjust the [MIN] tone for colors [R] and [B]. 6. View measurement points [No.], [No.], [No.0] and [No.]. Adjust the [R] and [B] of each measurement point so that they have the same color as measurement point [No.]. Adjustment technique: First, adjust [B:] of the point whose color is to be adjusted so that it approximates that of [No.]. 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.], [No.], [No.], [No.] and make similar adjustments. 8. Then adjust measurement points [No.6], [No.7], [No.8], [No.9], [No.], [No.], [No.6] and [No.7]. This completes the [MIN] tone adjustments. 9. Make similar adjustments for other tones, except the [MID-] and [MID-6] tones, as described in steps to 8 above.

13 CP-A / ED-A0 / ED-A (AB-0) -0 Installation Suggestions for CP-A/ ED-A0/ED-A The suggested projection image size is from 60 to 00. It is recommended to check if the focus performance is acceptable for your needs when projecting at larger than 00. It is strongly suggested to use the board-type screens with fl at 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 or/and the focus may change during the warm-up (approx. 0 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 fi xed 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 or/and the projected image size may change during the focus adjustment. The projected image position or/and the focus may change during the warm-up (approx. 0 minutes after the lamp is turned on.). The projected image size or/and its position may change due to the ambient condition, such as temperature or/and humidity changes. The projected image position may change after the installation (allow about week to stabilize). Step Roughly adjust the focus to match the screen size after mounting the projector to the boom. Keep the projector running for more than 0 minutes after focus adjustment. Step 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 Adjust the focus if the focus changed after the adjustment of the projected image size and position. Go back to the Step if the image size goes over the margins after the focus fi ne-tuning. Screen size [inch] Vertical margin [mm] Horizontal margin [mm] Vertical margin Horizontal margin Projected Image Screen Horizontal margin Vertical margin CAUTION This projector is not allowed to be used for vertical installation like tabletop use.

20 6. Service points 6- Lead free solder [CAUTION] CP-A / ED-A0 / ED-A (AB-0) This product uses lead free solder (unleaded) to help preserve the environment. Please read these instructions before attempting any soldering work. Lead free solder indicator Printed circuit boards using lead free solder are engraved with an "F" or "LF". Properties of lead free solder The melting point of lead free solder is 0-0 C higher than leaded solder. Servicing solder Solder with an alloy composition of Sn-.0Ag-0.Cu or Sn-0.7Cu is recommended. Although servicing with leaded solder is possible, there are a few precautions that have to be taken. (Not taking these precautions may cause the solder to not harden properly, and lead to consequent malfunctions.) Precautions when using leaded solder Remove all lead free solder from soldered joints when replacing components. If leaded solder should be added to existing lead free joints, mix in the leaded solder thoroughly after the lead free solder has been completely melted (do not apply the soldering iron without solder). Servicing soldering iron A soldering iron with a temperature setting capability (temperature control function) is recommended. The melting point of lead free solder is higher than leaded solder. Use a soldering iron that maintains a high stable temperature (large heat capacity), and that allows temperature adjustment according to the part being serviced, to avoid poor servicing performance. Recommended soldering iron: Soldering iron with temperature control function (temperature range: 0-0 C) Recommended temperature range per part: CAUTION Always wear safety glasses to prevent fumes or molten solder from getting into the eyes. Lead free solder can splatter at high temperatures (600 C).
