1. Use the tilt stand 
Setting up the tilt stand allows you to raise the projected image. 
Two positions tilt stand allow you to set up projection angle to either 5°or 10°. 
The more inclination angle is added, the higher the image is projected. 
 
 
 
2. Reset the position of the projected image. 
The projector will project horizontally when the tilt stand is folded to the first 
position.

How to use the protective cover 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Cover the projector to protect it from damage. 
■ Be sure to firmly hold the bottom of the projector and avoid applying an 
excessive vibration or impact when you carry the projector with the 
protective cover. The projector may slip out of the cover and drop to the 
ground, causing malfunction of the projector.    
■ Do not use the projector with the protective cover on it. 
Doing so can cause the protective cover to get extremely hot, and 
possibly resulting in burn or injury. 
■ The projector will remain hot for a while after it is turned off. Put the 
protective cover on the projector after it is cooled down. Otherwise, the 
projector may become defective. 
 CAUTION

Use the protective cover as a projection stand. 
◎Change the projection angle by adjusting 
the position of the tape. 
 
■ When using the protection cover as a projection stand, observer the 
following precautions for safety use of the projector.    
- Do not look into the lens while the projector is being used. Strong light 
is emitted from the projectors lens. If you look directly into this light, it 
can hurt and damage your eyes. Be especially careful not to let young 
children look into the lens. 
- Do not touch the ventilation outlet as it can become heated while the 
projector is turned on and immediately after the projector is turned off.
