[. . . ] Your serial number is located under the name plate label on the right side of your MultiSync MT830/1030 . Record it here: CAUTION TO PREVENT SHOCK, DO NOT OPEN THE CABINET. This symbol warns the user that uninsulated voltage within the unit may be sufficient to cause electrical shock. Therefore, it is dangerous to make any kind of contact with any part inside of the unit. [. . . ] (There is approximately 10. 5° of up and down adjustment for the front of the projector. If a trapezoidal distortion appears on the screen, use the KEYSTONE button on the remote control or select Keystone from the menu to correct the distortion. If necessary, adjust the front or rear feet so that the lens surface is parallel to the screen. If you use the projector with the screen tilted, the picture will be distorted. Increase or reduce the size of the projected image by pressing the "Zoom" (+) or (­) buttons on the remote control or top of the cabinet. 18 INSTALLATION 34 35 Distance Chart C A Formulas(mm) "H=Horizontal Screen Width M=1. 25H/33. 02(Projection magnification) A=C/cos C (WIDE)=53. 2 M-85. 609 C (TELE)=C(WIDE) 1. 3055 D ={(3H/8)-(92. 2+8M)} =1. 906M-92. 2 E=92. 2+8M Formulas(inch) "H=Horizontal Screen Width M=1. 25H/1. 3(Projection magnification) A=C/cos C (WIDE)=2. 09445 M-3. 37 C (TELE)=C(WIDE) 1. 3055 D ={(3H/8)-(92. 2+8M)}/25. 4 =(1. 906M-92. 2)/25. 4 E=(92. 2+8M)/25. 4 E D A: C: D: E: Distance between the lens and the screen center Horizontal throw distance between the screen surface and the lens Vertical distance between the projector bottom and the bottom of image Vertical distance between the projector bottom and the screen center 19 INSTALLATION 36 37 Standard Zoom Lens (Wide) (sin= ) (cos= ) Screen Size H­Width 4 : 3 Diagonal A C D E Degree 8. 70 8. 65 8. 73 8. 67 9. 02 8. 86 8. 81 8. 61 8. 78 8. 75 8. 64 8. 63 8. 62 0. 15671 0. 15395 0. 15318 0. 15260 0. 15216 0. 15181 0. 15128 0. 15076 0. 15041 0. 15024 0. 14998 0. 14984 0. 14972 0. 98764 0. 98808 0. 98820 0. 98829 0. 98836 0. 98841 0. 98849 0. 98857 0. 98862 0. 98865 0. 98869 0. 98871 0. 98873 32 48 56 64 72 80 96 120 144 160 192 216 240 inch inch mm inch mm inch mm inch mm inch 40 1572 61. 9 1552 61. 1 -34 -1. 32 339 13. 3 1. 91 30. 79 60 2400 94. 5 2371 93. 4 -4 -0. 16 462 18. 2 1. 94 46. 18 70 2814 110. 8 2781 109. 5 10 0. 41 523 20. 6 1. 95 53. 88 80 3228 127. 1 3190 125. 6 25 0. 99 585 23. 0 1. 96 61. 58 90 3642 143. 4 3600 141. 7 40 1. 57 646 25. 4 1. 97 69. 27 100 4056 159. 7 4009 157. 8 55 2. 15 708 27. 9 1. 97 76. 97 120 4884 192. 3 4828 190. 1 84 3. 30 831 32. 7 1. 98 92. 36 150 6127 241. 2 6057 238. 4 128 5. 03 1016 40. 0 180 7369 290. 1 7285 286. 8 172 6. 77 1201 47. 3 200 8197 322. 7 8104 319. 1 201 7. 92 1324 52. 1 240 9853 387. 9 9742 383. 5 260 10. 23 1570 61. 8 270 11096 436. 8 10970 431. 9 304 11. 96 1755 69. 1 300 12338 485. 7 12199 480. 3 348 13. 70 1939 76. 4 C/H-Width magnification 1. 99 1. 99 2. 00 1. 99 2. 00 2. 00 115. 45 138. 55 153. 94 184. 73 207. 82 230. 91 Standard Zoom Lens (Tele) (sin= ) (cos= ) Screen Size H­Width 4 : 3 Diagonal A C D E Degree 6. 69 6. 65 6. 71 6. 66 6. 62 6. 93 6. 81 6. 77 6. 75 6. 73 6. 64 6. 63 6. 62 0. 12065 0. 11850 0. 11790 0. 11746 0. 11711 0. 11684 0. 11643 0. 11603 0. 11576 0. 11562 0. 11542 0. 11531 0. 11522 0. 99269 0. 99295 0. 99302 0. 99308 0. 99312 0. 99315 0. 99320 0. 99325 0. 99328 0. 99329 0. 99332 0. 99333 0. 99334 32 48 56 64 72 80 96 120 144 160 192 216 240 inch inch mm inch mm inch mm inch mm inch 40 2041 80. 4 2027 79. 8 -34 -1. 32 339 13. 3 2. 49 30. 79 60 3118 122. 7 3096 121. 9 -4 -0. 16 462 18. 2 2. 54 46. 18 70 3656 143. 9 3630 142. 9 10 0. 41 523 20. 6 2. 55 53. 88 80 4194 165. 1 4165 164. 0 25 0. 99 585 23. 0 2. 56 61. 58 90 4732 186. 3 4699 185. 0 40 1. 57 646 25. 4 2. 57 69. 27 100 5270 207. 5 5234 206. 1 55 2. 15 708 27. 9 2. 58 76. 97 120 6346 249. 9 6303 248. 2 84 3. 30 831 32. 7 2. 58 92. 36 150 7961 313. 4 7907 311. 3 128 5. 03 1016 40. 0 180 9575 377. 0 9511 374. 4 172 6. 77 1201 47. 3 200 10651 419. 3 10580 416. 5 201 7. 92 1324 52. 1 240 12804 504. 1 12718 500. 7 260 10. 23 1570 61. 8 270 14418 567. 6 14322 563. 8 304 11. 96 1755 69. 1 300 16032 631. 2 15925 627. 0 348 13. 70 1939 76. 4 C/H-Width magnification 2. 60 2. 59 2. 61 2. 60 2. 61 2. 61 115. 45 138. 55 153. 94 184. 73 207. 82 230. 91 20 INSTALLATION 38 39 WARNING · Only use your LCD projector on a solid, level surface. If the projector falls to the ground, you can be injured and the projector severely damaged. · Do not use the LCD projector where temperatures vary greatly. The projector must be used at temperatures between 32°F (0°C) and 104°F (40°C). · Ensure that you have adequate ventilation around your LCD projector so heat can dissipate. Do not cover the vents on the side or the front of the projector. Ceiling Installation Installing your MultiSync MT830/1030 LCD Projector on the ceiling must be done by a qualified technician. Do not attempt to install the projector yourself. NOTE : Distances may vary ± 5%.
