2. Loosen the white lens adjustment joystick on the projector by twisting it
counterclockwise.
3. Tilt the joystick to move the lens into the proper position.
4. Tighten the white joystick by twisting it clockwise.
5. Push the lens brace clamps against the lens, making sure not to tilt the projection.
6. Tighten the four thumb screws.

Turning off the System

To shut down your system, you should turn off the control unit first, and then the DLP
projector.
To turn off the control unit:
1. With the remote control, use text menu item 8.3 (see the software manual for more
information). With the (optional) Universal Console interface, tap the shut down
button on the Settings screen.
2. If desired, flip the Control Unit power switch to the off position (0) when the shut
down process is complete.
To avoid corrupting the system, do not turn off the control unit during a
software update or while the indicator light is bright (indicates disk activity). If
necessary, you can simply turn off the control unit at the AC switch without
following step 1 above. However, this runs the risk of corrupting the system.
To turn off the DLP projector:
1. Press the power button of the DLP projector or DLP projector remote control twice.
It takes about two minutes to cool down the projector lamp safely. While cooling, the
power indicator light will be steady orange.
2. Put the lens cap on the fisheye lens to protect the lens.
3. When the DLP projector power indicator light is steady red, the projector has
completed its cooling process. You can now flip the power switch to off (0).
