Setting upGetting StartedENGLISH - 15Setting upScreen size and throw distanceYou can adjust the projection size with 1.2× zoom lens. Calculate and deine the throw distance as follows.SDSWSHL (LW/LT)SH88,6 mmL (LW/LT)SWProjected imageScreenScreen(All measurements below are approximate and may differ slightly from the actual measurements.)Projection size For 4:3 aspect ratio For 16:9 aspect ratioScreen diagonal (SD)Minimum distance (LW)Maximum distance (LT)Minimum distance (LW)Maximum distance (LT)0.84 m (33") — 1.1 m (3' 7")— 1.2 m (3' 11")1.02 m (40")1.1 m (3' 7") 1.4 m (4' 7")1.3 m (4' 3") 1.5 m (4' 11")1.27 m (50")1.4 m (4' 7") 1.7 m (5' 6")1.6 m (5' 3") 1.9 m (6' 2")1.52 m (60")1.7 m (5' 6") 2.1 m (6' 10")1.9 m (6' 2") 2.3 m (7' 6")1.78 m (70")2.0 m (6' 6") 2.4 m (7' 10")2.2 m (7' 2") 2.6 m (8' 6")2.03 m (80")2.3 m (7' 6") 2.8 m (9' 2")2.5 m (8' 2") 3.0 m (9' 10")2.29 m (90")2.6 m (8' 6") 3.1 m (10' 2")2.8 m (9' 2") 3.4 m (11' 1")2.54 m (100")2.9 m (9' 6") 3.5 m (11' 5")3.2 m (10' 6") 3.8 m (12' 5")3.05 m (120")3.5 m (11' 5") 4.2 m (13' 9")3.8 m (12' 5") 4.6 m (15' 1")3.81 m (150")4.3 m (14' 1") 5.2 m (17' 0")4.7 m (15' 5") 5.7 m (18' 8")5.08 m (200")5.8 m (19' 0") 7.0 m (22' 11")6.3 m (20' 8") 7.6 m (24' 11")6.35 m (250")7.3 m (23' 11") 8.7 m (28' 6")7.9 m (25' 11") 9.5 m (31' 2")7.62 m (300")8.7 m (28' 6")10.5 m (34' 5")9.5 m (31' 2")11.4 m (37' 4")You can calculate more detailed screen dimensions from the screen diagonal. The results below are approximate and may differ slightly from the actual measurements.If the projection size is SD,For 4:3 aspect ratio For 16:9 aspect ratioScreen height (SH) = SD (m) × 0.0152 = SD (m) × 0.0125Screen width (SW) = SD (m) × 0.0203 = SD (m) × 0.0221Minimum distance (LW) = 0.0292 × SD (m) - 0.036= 0.0318 × SD (m) - 0.022Maximum distance (LT) = 0.0351 × SD (m) - 0.044= 0.0383 × SD (m) - 0.046Note zFor the best quality of the projection image, install a screen where sunlight or room light does not shine directly onto the screen. Close window shades or curtains to block the light and turn off the lamps.Do not use the projector at a raised or a horizontally tilted position. Doing so may cause malfunction of the zprojector. You can tilt the projector body approximately ±30 ° vertically and ±10 ° horizontally. Overtilting may result in shortening the component’s life.Do not cover the air outlet port and air intake ports or place anything within z50 cm (20") of them as this may cause damage or injury.+30 °-30 °
