out, fit a new lamp.

• Check that the lens is fitted correctly.
• Check that the lamp and the lamp unit are prop-
erly fitted.

mode to adjust the focus.

to the instructions supplied with the carrier for
details.

mode to straighten the image.

ing up. Wait until the Start key turns green before
pressing it.
• If an error code is shown on the display, see "User
Call Errors" or "Service Call Errors".

not "Semi Auto". Check the application software
setting.
