230 DL.3 Digital Light User Manual
Image is blurry, out of focus,
or colors are unnatural •Check the F ixture filters (see page 17-217).
•Is the D L.3 mounted less than 1.4 meters to an object? If so, move the DL.3
farther away to enable it to focus properly.
•Make sure the DL.3 is no t operating near fog machines, hazers, or mineral
oil hazers (see See “Fog Machine Warning” on page 8.)
•Clean the front w indow (see “Cleaning or Replacing the Front Window” on
page 17-223).
•Check the lamp (see the projector manual shipped with the DL.3).
•If you’re using the projector ’s on-screen programming system, you can
override zoom and focus using the menu system (see “Projector Control” on
page 14-181.)
The LCD Menu display is off •If the Blue LED is off, the Computer isn’t receiving power. Press and hold
the Top and Bottom Tab select buttons to restart computer, (see “Menu
Panel Components” on page 3-21.)
•If the screen is not backlit, press the LCD power button, (see “LCD Display
Adjustment Buttons” on page 3-22.)
•Check the Video In Video Out adapter on the video card (middle plug)

Fixture behaves erratically or
won’t respond to DMX
control
•Verify that the last unit on the DMX link is properly terminated, (see “Setting
up a Standard DMX Link” on page 2-10.
•To control the DL.3 with DMX, you must first enable DMX through the menu
System (see “DMX_Control Screen” on page 3-27) or the CMA (see “DL.3
and DL.2 Media Server Configuration Options” on page 16-208).
•If you’re using DMX to control the projector using its native menu system,
make sure you send a safe command after each button command;
otherwise, it’s analogous to pressing a button on the projector menu system
and not releasing it (see page “Projector Control” on page 14-181).
