AUDIO OUT
All Desktop Projector models contain an internal stereo system
consisting of an amplifier and two speakers. Although this system
provides high quality stereo output, a multimedia presentation
may require connecting the projector to external powered speakers
or an external sound system.
External Speakers
When connecting external speakers, use the optional Proxima
Powered Loudspeaker System (part number A55) or a similar
system. References in the following procedure are to Figure 2-12.
To connect your Desktop Projector to external powered speakers:
1. Insert the mini plug of the stereo cable (supplied with your
powered speakers) into the projectorÕs AUDIO OUT
connector.
2. Insert the other end of the cable into speaker A.
3. Connect speaker A to speaker B using the cables supplied with
the speaker system.
Note:  The projectorÕs internal speakers canÕt be disabled or
turned off.

CAUTION! Locate the air intake and exhaust grills on the top
cover and to the left and right sides of the projection mirror
assembly, and the exhaust grills on the rear panel and side of the
projector. Never operate the projector if these grills are clogged or
obstructed, or if the electric fans are not running.
Figure 2-15
Allow for proper air flow!
CAUTION! The lamp chamber gets very hot during
operation. In particular, the ceramic socket at the lampÕs base can
get extremely hot! Use appropriate care when opening the lamp
chamber or changing lamps. Make sure that the lamp chamber
and lamp have cooled for at least 6 minutes with the fan running.
To do so, press the LAMP button to turn off the lamp and allow
the fan to operate for several minutes.
Note: If you turn the Desktop Projector off while the rest of
your computer system is running, your external monitor will go
blank. This is normal. Just turn the Desktop Projector on again
and your monitor display will return.

Correcting Keystoning
The normal projected image will have a rectangular shape.
Keystoning is when the projected image becomes trapezoidal.
Normal Image Keystoned Image
Figure 2-19
Normal vs. keystoned images
Keystoning occurs when the front of the Desktop Projector is not
perpendicular to the projection screen (the vertical plane) or when
itÕs not placed parallel to the floor (the horizontal plane). Key-
stoning also occurs when the projector is tilted sideways.
To correct keystoning, always make sure that the projector is at a
right angle to the screen in the horizontal plane. The projector is
properly aligned if the top and bottom of the projected image are
equal in length and parallel to the floor.

Positioning the Desktop Projector
In order to allow you to project images high enough for the entire
audience to view, the Desktop Projector has been designed to
minimize keystoning. A 10.5° correction for keystoning is built
into the projector.
