GENERAL FEATURES
The Firefly™ P350 is a full-color compact LCD projection system that is
used to display a computerized multi-media presentation. The built-in
amplifier/speakers lets you connect to a wireless microphone, portable
CD player, or to the auxiliary output of a stereo system. The P350 also
allows you to connect to the output of a VCR or LaserDisc player.
The P350 is equipped with a monitor interface connector. This allows
you to simultaneously view your computer video on both the small and
large screens. Figure 1 shows the P350 in use to project

User Manual 1
The Firefly™ P350 can be connected to any IBM or IBM compatible
computer equipped with a VGA/SVGA video output. The P350 can also
be connected to any Apple Macintosh computer that is equipped with a
standard Macintosh video output.
The Firefly™ P350 uses advanced thin-film-transistor liquid crystal
display (TFT LCD) technology and is capable of displaying up to
16,194,277 colors. The fast response time of the P350’s TFT LCD
provides you with the ability to display sharp, clear, fast-moving images.
The P350 liquid crystal display is a matrix of 1.44 million pixels arranged
in 600 rows x 800 columns x 3 colors. Each pixel is a single
thin-film-transistor that actively controls the brightness of the light that
passes through the pixel.
To protect the P350 from excessive heat, it is equipped with several
cooling fans. One of these fans is running whenever the P350 is
plugged in, the other fans are turned on whenever the LCD notebook
projector is turned on.
The keypanel and on-screen controls allow you to change the video
source, color, tint, focus, position, etc. of the projected color image; and
change the volume and tone of the sound.
