1.1 About the Bengal
The Clarity Bengal is a 61" rear-projection display in a native 16x9 format, designed to outperform large
format plasma displays. It combines ultra-thin (6.5" deep) rear projection, DLP technology and rugged
reliable design for outstanding performance in digital signage applications.
Scale
Bengal will up sample resolutions up to a resolu-
tion of 1280 x 720 (720p), and will downsample reso-
lutions up to 1600 x 1200.
Video inputs
A standard 15-pin VGA connector accepts com-
puter pictures up to 1600 X 1200. It also accepts
video RGB with separate H&V Sync, composite sync
and sync on green.
A DVI connector accepts computer images as well
as Digital Video.
An S-Video input is available using a standard 4-
pin Din connector.
A component video input is available as Y, Pb, Pr
on three RCA connectors color coded green, blue and
red.
A composite video input is available on a yellow
RCA connector.
Audio
There are three stereo audio inputs using RCA
connectors. There is an output connection for exter-
nal stereo speakers as well as a line out to be used as
an input to an external stereo amplifier.
Communication
Communicating with the Bengal will be done via
an RJ45 RS232 input or an RJ45 RS485 input. Loop
through from either source will be via an RJ45 RS485
output.
Display Technology
The display technology is single chip DLP.
Service
The Bengal is completely serviceable from the
front. All parts replacement should be performed at
the module level by a qualified service technician.
Lamp life
Median lamp life is rated at 4000 hours. This
means that of a large sample of lamps, at the end of
4000 hours, half of the lamps will still be lit. The
remaining half could have failed at any time prior and
the surviving half could perform well for several thou-
sand hours more. See 5.1 “Changing a Lamp” on
page 56 for more information on when to change a
lamp.

1.4 Your Safety is Important
The Bengal produces UV (ultra-violet) radiation (internally), and some parts are very hot. For your con-
tinued health and safety we strongly suggest you read this section carefully.
The fully assembled display weighs about 106 lb.
(48.08kg). When unpacking and installing the Ben-
gal, you will need two people to handle it.
WARNING
The lamp gets very hot. Allow it to cool fo 15
minutes before removing it.
WARNING
The lamp produces lots of light and UV radia-
tion (ultra-violet) as well. UV light can damage
your retinas. After the light leaves the lamp
and passes through the DLP optical engine,
there is no significant UV, although the light
will be very bright.
WARNING
There is no electrical interlock on the screen.
Removing the screen does not turn off the
high voltage to the lamp.
WARNING
Possible UV exposure. Use protective eye
wear while operating with viewing screen
removed.
CAUTION
There are no user serviceable parts inside.
Refer all repair and maintenance to a qualified
service technician.
WARNING
There are protective electrical interlocks
behind the left and right access panels.
Removing the access panels will cause the
lamp to turn off. Defeating these interlocks will
risk exposure to UV.
Static electricity can damage sensitive electronic com-
ponents.
• Always use a grounding strap when handling the
electronics module or the optical engine if there
are exposed components.
• When shipping these parts, do not use styrofoam
“peanuts.” These carry static electricity and can
damage the parts. Use an anti-static bag, or, if
that is not available, wrap the electronics module
in aluminum foil.
