INSTALLATION AND ASSEMBLY 24 (1) Weight-tolerant The ground must be flat and horizontal. It should be able to bear the weight of the system. For wooden floors, if the part receiving the weight of the system lies at the center between the reinforcement beams below the floor, the floor may become deformed or may curve inwards.
25 INSTALLATION AND ASSEMBLY (6) Installation work to prevent toppling ¶ Make sure that you carry out the following work after installing the system in order to prevent toppling etc. 1 Lower all of the floor levelers until the system comes into contact with the floor.
INSTALLATION AND ASSEMBLY 26 (7) Heat value calculation ¶ In the calculation, assume that the maximum power consumption per multi-projection unit is 300 W by re- serving a certain headroom. As most of the consumed power becomes heat, the power consumption can be regarded to be proportional with the calorific value.
27 INSTALLATION AND ASSEMBLY (10) Visual field angles, visible range ¶ Uniform images can be obtained by installing the system in any of the ranges shown below. Vertical field angle ¶ 2-stage configuration ¶ 3-stage configuration [Fig. 3-1-2] [Fig.
INSTALLATION AND ASSEMBLY 28 ¶ 3-stage configuration using stands (RMA-V5020) ¶ 2-stage configuration using stands (RMA-V5020) [Fig. 3-1-4] [Fig. 3-1-5] 1.
29 INSTALLATION AND ASSEMBLY ¶ 3 horizontal screen configuration Horizontal field angle ¶ 2 horizontal screen configuration [Fig. 3-1-6] [Fig. 3-1-7].
INSTALLATION AND ASSEMBLY 30 (11) Lighting ¶ Projection screens do not reflect external light like the CRT, but the screens and their base materials may still cause reflection if strong light of a spotlight, etc. is directly incident to them. In such a case, prevent the illumination lighting from hitting the screen surfaces directly.
31 INSTALLATION AND ASSEMBLY (14) Power supply 1 Power supply voltage The guaranteed voltage of this system is ±10% of the rated voltage. But if the impedance of the power wires is high, the voltage waveform will become distorted and show the same symptoms as when voltage drops abnormally.
INSTALLATION AND ASSEMBLY 32 4 3-pin plug The power cord of the system has a 3-pin plug. This design aims at preventing electric shock due to leaked current.
33 INSTALLATION AND ASSEMBLY [Fig. 3-1-8] [Fig. 3-1-9] (18) Ventilation To prevent the rise in the internal temperature, the system is equipped with a vent and a vent with a fan on the top panel and vents on the bottom and rear panels.

111 ADJUSTMENTS (5) White balance adjustment 1 Before adjusting white balance Adjusting the white balance means to adjust the color tone. This adjustment is necessary for the screen to become white when the white signal is input, and black when the black signal is input.
112 ADJUSTMENTS 3 Adjustment flow [1] Perform the adjustment using the full white (variable by %) signal generator. [2] Perform the COLOR, TINT, and SHARPNESS adjustments. [3] Note down or memorize in the PC memory the data after the rough adjustment.
113 ADJUSTMENTS 5 Rough adjustments (1) Black level adjustment Signal:White 10% Adjust R LOW, G LOW, and B LOW to the point where the CRT starts lighting up. (2) HI LIGHT adjustment Signal:White 50% Adjust R HI, G HI, and B HI so that the CRT becomes white.
114 ADJUSTMENTS 7 ABL GAIN adjustment (White 100%) The ABL GAIN adjustment adjusts the white 100% luminance of a unit to other units after low luminance and medium luminance have been adjusted. Normally, when white 100% is input, ABL is imposed and the current is controlled so that the current flowing in the CRT does not exceed a certain level.
115 ADJUSTMENTS 9 Adjustment using moving images The adjustment using images adjusts the overall joining of the screens by loading discs used by users (for actual performance) and discs always used for adjustments. View the overall screen and adjust the screen with the greatest difference to the other screens.
116 ADJUSTMENTS 3 Color adjustment (White balance) (a) Effects of brightness ¶ Take note of dark images which have some high luminance parts. ¶ The reflected light overlap with surrounding dark parts at the face of the CRT and surface of projection lens, and luminance and hue become different from the adjoining screen.
117 ADJUSTMENTS (6) External control by MPJ RS-232C As MPJ is equipped with a RS-232C port, various controls and, white balance and convergence adjustments can be performed by an external computer. By programming software ,it is possible not only to adjust White Balance,Convergence but to save and control the adjustment data of each source.
