8 CP-XN(CI-N) / CP-XN(CI-N) / CP-XN(CI-N) / CP-XN(C-N) / ED-XN(C-N) 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. and No.. The values should be: No. = Y [lx] No. = Y [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. and No. adjustment points have the average of Y and Y. Y = ( Y + Y ) / ± [%] Y = ( Y + Y ) / ± [%]. 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.. 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- 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.. Measure the color coordinates of measurement point [No.] and adjust [No.][R:] and [B:] so that the coordinates are as follows. x = x ±., y = y ±. 9. Similarly, measure adjustment points [No.] to [No.] 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.] ± or less [No.] to [No.9] ± or less [No.] to [No.] ± or less [No.] to [No.] ± or less. 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 ±., y = y ±. (Target) x = x ±., y = y ±.. Similarly, measure adjustment points [No.] to [No.] 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].). Now make similar adjustments for [MID-], [MID-], [MAX] tones. (It is not necessary to adjust the [G] data in these tones.). After completing the step, 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.. Set all the values for the [No.] to [No.] of the [MID-] tone [R] and [B] in the same way as the step. 9. Finally, set the data of the [MID-] 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 and.

9 CP-XN(CI-N) / CP-XN(CI-N) / CP-XN(CI-N) / CP-XN(C-N) / ED-XN(C-N) 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.] 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].. View measurement points [No.], [No.], [No.] 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.. Next, view measurement points [No.], [No.], [No.], [No.] and make similar adjustments.. Then adjust measurement points [No.], [No.], [No.], [No.9], [No.], [No.], [No.] and [No.]. This completes the [MIN] tone adjustments. 9. Make similar adjustments for other tones, except the [MID-] and [MID-] tones, as described in steps to above.

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 - C higher than leaded solder. Servicing solder Solder with an alloy composition of Sn-.Ag-.Cu or Sn-.Cu 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.
