[. . . ] These characteristics often go unnoticed in a visual inspection, and the protection afforded by them cannot necessarily be obtained by using replacement components with higher ratings (voltage, wattage, etc. ). Replacement parts having special safety-related characteristics are identified in this manual, and in the schematic diagrams, by the symbol !These components have values that are of special significance to product safety. Should any component (identified by the symbol ) need to be replaced, use only the part designated in the parts List. [. . . ] However, the last monitor termination switch should be the 75 ohm position for proper line termination. 2. Video input terminals (VIDEO IN) These terminals are used to input a video signal source to this monitor. Connect to the video output of a VCR or another monitor (for loop through connection) or to a video camera. 6. Sub-brightness control (SUB-BRI) Turn to adjust picture brightness. 7. Vertical Size control (V-SIZE) Turn to adjust picture vertical size of the picture. 8. Video output terminals (VIDEO OUT) These terminals are used to output a video signal for this monitor. Loop-through output of the video in BNC connector, then connect to the video input of another monitor or a VCR. If the picture is scrolling up or down on the screen, turn this control until there is a single steady picture. 4. Termination Switch (HI/75 (Lo)) Select the input impedance (HI/75 ohm). When using only one monitor, turn the termination switch to the 75 ohm position. When using more than one monitor, set all of the termination switch to the monitors to the HI position. ­5­ 1 4 2 Fig. 4 3 68 7 Single Connection To Video B INPUT terminal (Video signal cable) Monitor To Video A INPUT terminal (Video signal cable) Video recorder To Video input terminal To Video input terminal Video recorder Video camera (Rear panel) Monitor Fig. 5 Coaxial cable To Video input terminal Monitor Video recorder Video camera Fig. SERVICE ADJUSTMENTS ADJUSTMENT ITEM VERTICAL LINEARITY ADJUSTMENT HORIZONTAL HOLD ADJUSTMENT GEOMETRICE DISTORTION PATTERN ADJUSTMENT VIDEO CENTERING ADJUSTMENT VIDEO TILT ADJUSTMENT TIMING PATTERN SETTING VR LOCATION VR303 ADJUSTMENT PROCEDURE Adjust VR303 to make equal distance between top-center and bottom-center.
