tion can be done with the USB mouse, remote control or cabinet buttons.

Tips on Adjusting Focus
Optimum focus adjustments can be achieved on the projector
by paying special attention in a few areas.
Focus adjustment after the projector has warmed up to
normal operating temperature is better than doing so when
the projector is cold.
Lens mechanism interacts differently when adjusting focus
from one direction to the other.
For this reason final focus adjustments should be done in a
specific direction.
For optimum focus, follow the steps below.
For the zoom and the lens shift adjustment, perform the
normal procedures.
Preparation (Recommended):
Warm up the projector for about 60 minutes.
Adjusting the Focus
1. Practice focusing
Use the FOCUS (+) or (-) button on the projector or the remote
control to increase or decrease the focus values to verify the
accuracy of focusing.
2. Try optimizing defocus
Use the FOCUS button (-) to decrease the focus values until pixel
patterns are too blurry to be visible.
3. Obtain correct focus
Use the FOCUS button (+) to obtain the best focus. Do not use the
FOCUS (-) button at this time.
Finally store the adjustments in memory.
If you adjust beyond the best focus point, go back to step 2 and
repeat the procedures. Always adjust the focus from the negative
direction towards the positive direction.
