Connect the ground terminal of the AC inlet of this unit to the ground terminal provided in the building using an optional three-core power supply cord. • Always use the liquid crystal projector in a horizontal position, if possible. If you operate the liquid crystal projector with its lens upwards, its lens downwards or to the side, the heat generated inside the projector may build up and cause malfunctions or damages. Be especially careful to never block the ventilation holes. • Do not install the LCD projector in a smoky surrounding, since smoke residue may be accumulating on critical parts (i.e. LCD panel, lens, etc.). Angle Adjustment Use the foot adjusters located on the bottom of the projector to adjust the angle of projection. This angle can be adjusted within approximately 0° to 9°. 1 Lift up the front side of the projector and press the button of the foot adjuster to adjust the angle of projection. 2 To lock the foot adjuster at the desired angle, release the button. 3 Turn the screw of the foot adjuster to precisely adjust it. Do not use force, since this could damage the adjuster or result in a failure of the lock. Foot Adjusters CAUTION Variable within the range of approximately 0°-9° • Do not release the foot adjuster button unless you hold the projector, or else the projector may overturn or the fingers may get caught. 6 ViewSonic PJ1065
