CAUTION • Install the projector in a suitable environment according to
instructions of the accompanying manual "SAFETY INSTRUCTIONS" and this
manual.
• Please basically use liquid crystal projector at the horizontal position. If you use
liquid crystal projector by the lens up position, the lens down position and the side up
position, this may cause the heat inside to build up and become the cause of damage.
Be especially careful not to install it with ventilation holes blocked.
• Do not install LCD projector in smoke effected environment. Smoke residue may
buildup on critical parts (i.e.LCD panel, Lens Assy etc.).

Angle Adjustment

Use the foot adjusters on the bottom of the
projector to adjust the projection angle. It is
variable within 0˚ to 9˚ approximately.
1. Lift up the front side of the projector, and
pressing the foot adjuster button, adjust the
projection angle.
2. Release the button to lock at the angle to be
fixed.
3. Make the foot adjusters screw for fine
adjustment. Do not force the adjusters to make
screw. This could damage the adjusters or
cause the lock to fail.
CAUTION • Do not release the foot adjuster button unless the projector is
being held; otherwise, the projector could overturn or the fingers could get
caught and cause personal injury.
