Hitachi Sales Europa GmbH WPOWER S O U R C E This colour display is designed to operate on 220/240 volts 50 Hz, AC. Insert the power cord plug into a 220/240 volts 50 Hz safety grounded outlet. DO NOT CONNECT THE DISPLAY TO OTHER THAN THE SPECIFIED VOLTAGE. Never remove the back cover of the display as this can expose you to very high voltage and other hazards. If the display does not operate properly, unplug the display and call your dealer. NOTE : 1. This colour display is equipped vith a three-vire type plug. This plug will only fit into a grounding-type power outlet. This is a safety feature, do not defeat the safety purpose of the grounding-type plug. 2. If the power cord or plug is damaged or frayed, replace it. 3. Do not overload wall outlets or extension cords as this can result in fire or electric shock. TO PREVENT SHOCK OR FIRE HAZARD, DO NOT EXPOSE THIS DISPLAY TO RAIN OR MOISTURE.. 3 CAUTIONS ON USE CAUTIONS ON THE SUPPLY VOLWhen the power voltage is extremely high or low, it may cause trouble or it may not give optimum performance. Consult your dealer at that time. KEEP WATER OUT When water of liquid enters the set, it becomes dangerous to use the unit. Immediately pull the plug out and contact your dealer. KEEP IN A WELL VENTILATED PLACE Ventilation holes are provided in the cabinet to prevent the temperature from rising. Do not place the unit in a place badly ventilated or cover the unit with materials such as clothes. HIGH TEMPERATURE CAUSES TROUBLE Avoid placing the unit in direct sunshine, near a heating appliance. WHEN BEHAVIOUR IS ABNORMAL When any abnormal sound, odour or smoke is generated, push the power switch off, pull the power plug out from the socket and contact your dealer. CAUTIONS TREATING THE SURFACE Do not wipe the surface of the set using volatile liquids such as benzine or thinners, or any chemically treated cloth; do not apply insecticide. It may damage the surface or cause peeling-off of the paint. When a vinyl product is kept in contact with the surface for a long time, stains may occur. BE CAREFUL OF MAGNETISM Do not bring materials which generate magnetism, such as a magnet, printers, floppy discs, or transformers etc. nearby: the set may be affected by magnetism, causing colour disturbance or picture distortion etc. 5 LOCATION OF CUSTOMER CONTROLS [FRONT vmwl BRIGHTNESS CONTROL CONTRAST CONTROL / / DEGAUSSING SWITCH POWER SWITCH "0" means power on. "I" means power off. \ POWER INDICATOR (This illuminates when power is on.) Fig. 1 CONTRAST AND BRIGHTNESS CONTROLS These may be adjusted by releasing the push in/out rotary controls. DEGAUSSING SWITCH This display is equipped with an automatic degaussing circuit (This circuit operates when power is switched on). If the display is turned horizontally and picture colour becomes un-uniform, push this switch to get fine colour uniformity. Picture may become still after some ten seconds. 6 [REAR VIEW] R.G.B.

This document lists the ad.iustmcnt fcat,rlrrs of thr 20738 available to the dealer. Other ad.justment.s exist which are not readily accessible and should not be attempted by untrained personnel. The CM2073A comes in various configurations including displays for line rates of nominal 50kHz and 60kHz operations, line synchronisation on the green video drive9 separate line synchronisation, with or without D.D.C. (Dig:ital Dynamic Convergence) and models with internal timing to preferred video driving boards. Before any of the adjustments below are attempted, please ensure that the model has been chosen appropriately from the options listed on page 16 of the operating guide. The adjustments listed in this note permit some deviations from this table, but it is important that the most appropriate model be chosen. ,' 1 ADJUSTMENTS Before attempting any of the following adjustments, the display should be powered up for a period of 15 minutes prior to the ad-justment. 1. Switch on the power9 noting that. the green power indicator adjacent to the power switch comes on, If it does not; a> Check power source and connections b) Check fuse c) Call a service engineer I .:. 10 2. Advance the contrast and brightness controls fully clockwise. * ..* .+l 3. If no picture appears check the video drive and source connections particularly green for sync on green models or composite sync if there is a separate line. No picture will appear without the sync signal. 4. When a display appears note the stability of the displayed image. If it is not stable or it is displayed from centre, switch off the mains supply and remove outer plastic case only by removing four screws from the rear panel and two screws from the centre portion. It may be convenient to remove and replace signal and power cables at this stage, since they pass through the rear cover. See Fig.10. SCREW i COVER BACK COVER BOTTOM COVER " SC ii E L"J 1 Fig. 10 11 5. Power up and adjust (if necessary) the horizontal hold control with plastic trimmer (Fig.ll). Note that it is important that a plastic trimmer is used. Otherwise the adjustment could result in a short circuit and breakdown of display. 6. Adjust vertical hold control (if necessary) with plastic trimmer. 7. Either of the two previous controls should stabilize the picture. If not, call the service engineer. 8. With a stable picture, note the size and its position of the picture. Any adjustment shoud be made in the following sequence. Horizontal Centre 1 Horizontal Size ! Vertical Centre Vertical Size i . , /. Figs 11 and 12. B CUTOFF G CUTOFF R.CUTOFF E EKG \ G. EKG /R EKG / H. PHASE Q II 41 ui H SIZE H \ \ CENT I I Fig. 11 Fig. 12 12 9. With the previous adjustments complete YOU shoud now have a stable picture correctly centred. Check the left and right hand edges of the picture for clarity. If any corruption is present, it is necessary to adjust the horizontal phase until both extremities are clear. If adjustment is necessary, the horizontal centre and size may need further adjustment. 10. Display a picture that contains vertical lines at both right hand and left hands of the screen. If necessary, adjust the pin cushion control to make the lines straight. 11. Display a picture that contains a multiplicity of horizontal lines with constant spacing. If the lines are not displayed with equal spacings adjust the vertical linearity. If this adjustment is necessary, some readjustment of the vertical centre and size may be required. 12. Display a picture that contains a large white area and check that the displayed image is white. If it is not, an unqualified engineer shoud not attempt to adjust the colour drives or background to compensate. A qualified engineer must first determine that the black level pedestal is correctly positioned before any such adjustment is considered. This work involves further dismantlement of the chassis. 13. If in doubt or experiencing difficulty with the adjustments detailed, contact the supplier of the equipment. 14. In all of the above adjustments, ensure that the viewable displayed image does not exceed a displayed field of 380 mm X 270 mm. Finally, power down and replace covers and centre case portion first. Turn brightness and contrast controls to their normal operating positions. 13 c 5; FREIE UND HANSESTADT HAMBURG ARBEITS - UND SOZlALBEHkDE AMT FUR ARBEITSSCHUTZ Gesch (Bei -Z AS 23!FBA Ro Fernsprecher 29188 3135 (Durchwahl) Beantwortung bttte anqehen) Pulassungsschein HH 22/86 Ro A u f g r u n d 5 7 A b s . 2 d e r Rentgenwerordnung w o r n 01.
