7Align the projector adapter with the holes on the bottom of the projector and securely attachthe adapter with the four supplied screws (M4x20).Loosen the vertical adjust/arm fixation knobs of the pr ojector adapter.Caution Do not try to attach the projector adapter without the foam packing spacers inplace. Otherwise the mirror section may be subject to excessive force, which canlead to a shift in the pr ojected image and cause serious damage.Vertical adjust/arm fixation knobsWarningare used, the projector may be seriouslydamaged, or the projector may fall andcause injury. Be sure to use only thesupplied screws.2. Attach the wall adapter to the structural material of the wall.To ensure a projected image without distortion, the center of the wall adapter and the center ofthe screen should be aligned on a straight axis.• The wall adapter has a top/bottom orientation. Be sure to attach it with correct orientation.Caution If the wall adapter is mounted with reversed top/bottom orientation, correctinstallation is not possible.• The wall adapter can be adjusted horizontally over a range of ±50mm.Side with cutouts facing upSide without cutouts facing downWarningIf screws other than the supplied onesMounting the ProjectorUse only M6 (1/4 inch) screwsor bolts (4 locations) to fix the walladapter.

Determine the position for frontprojection.on page 2 of this manual are met.• Because the M260XS/M300XS/M350XS/M260WS/M300WS have a large optical axiselevation angle, a slight shift in projection distance will have a large effect on the screensize and position. If the projector angle is off, image distortion will increase.Preparations2. Make sure that all conditions described in the section "Heed the Following"1212
