Adjusting the projector's elevator
When the place to put the projector is slightly uneven to the left or right, use the
elevator feet to place the projector horizontally.
Using the feet can also tilt the projector in order to project at
a suitable angle to the screen, elevating the front side of the
projector within 11 degrees.
This projector has 2 elevator feet and 2 elevator knobs. An elevator foot is
adjustable while pulling up the elevator knob on the same side as it.
1.
Holding the projector, pull the elevator knobs up to loose the elevator feet.
2.
Position the front side of the projector to the desired height.
3.
Release the elevator knobs in order to lock the elevator feet.
4.
After making sure that the elevator feet are locked, put the projector gently.
5.
If necessary, the elevator feet can be manually twisted to make more precise
adjustments. Hold the projector when twisting the feet.
CAUTION ►Do not handle the elevator knobs without holding the projector,
since the projector may drop down.
►Do not tilt the projector other than it elevating its front within 11 degrees using
the adjuster feet. A tilt of the projector exceeding the restriction could cause
malfunction or shortening the lifetime of consumables, or the projector itself.
