Adjusting the projector’s elevator
You can use the elevator feet to make adjustments if the surface on which you 
need to set the projector is uneven or if you otherwise need to adjust the angle of 
projection. The adjustment range of the elevator feet is 0 to 9 degrees.
1.Press and hold in the elevator buttons while holding the projector. The 
elevator buttons and the elevator feet are on the both sides.
2.Raise or lower the projector to the desired height and release the elevator 
buttons. When you release the elevator buttons, the elevator feet will lock into 
position.
3.If necessary, you can also finely adjust the height of the projector by twisting 
the elevator feet by hand.
►Do not adjust the projector’s elevator during use or 
immediately after use. Handling while the projector is in a high temperature  
could cause a burn and/or malfunction to the projector. Before operating, make 
sure that the power switch is off, that the power cord is not plugged in, and that 
the projector is cool adequately.
►If you press the elevator button without holding the projector, 
the projector might crash down, overturn, smash your fingers and possibly 
 
result in malfunction. To prevent damaging the projector and injuring yourself, 
always hold the projector whenever using the elevator buttons to adjust the 
elevator feet.
