1.1 What is the VN-3820-VA (VN-3830-VA)?
The Clarity VN-3820-VA and VN-3830-VA were designed for overhead displays, where several units
are used side-by-side. They display analog VGA signals, just like a computer monitor, using bright
LCD projection technology. They can be controlled with RS-232 signals or with an IR remote control
(supplied). The 3830 model has a brighter lamp, but at the cost of a shorter lamp life. Otherwise, the
two models are the same.
These displays use LCD projection technology
for an image that is bright all the way to the
corners, even in well-lit environments such as
shops, restaurants and sports arenas. The 3800
series, with a 38" (965mm) screen, measured
diagonally, was designed for applications where
several units are lined up side-by-side in a
banner configuration. They are usually mounted
above the viewers. The screen tilts down at a
10° angle for optimum viewing in these
applications.
This manual covers both the VN-3820-VA
and the VN-3830-VA. The only difference
between them is that the 3830 is 20% brighter
but with half the average lamp life. In this
manual the term VN-3820-VA will mean either
model, unless specifically stated otherwise.
Model Average Life Brightness
VN-3820-VA 8,000 hours 125 fL
VN-3830-VA 4,000 hours 150 fL
!Note: Average lamp life of 8,000 hours means that
after 8,000 hours of use half the lamps will
still be functioning (and half won’t).
The VN-3820-VA is shipped with the cable tray
removed for easier installation. Plastic buttons
are in place to cover the side-to-side mounting
holes. The batteries are already in the remote
control.
Standard accessories:
• One 3 m 10A IEC power cord
• One 3 m HD15 D-sub VGA patch cable
• One remote control with batteries
installed
• One upper mounting rail (hanger rail)
• One lower mounting bracket
• Three bolts, washers and nuts for bolting
the displays side-to-side
• Two end caps with screws for the lower
cable channel doors, left and right ends
• Two bolts for securing the unit to the
lower mounting bracket
• One cable channel door (not really an
“accessory,” but it comes in the
accessories box)
• One User’s Guide (this manual)
Optional accessories:
• A pair of strong magnets to remove
screens in the middle of a banner display
(SRT-200).
• Lock for channel cover (VN-38-LK)
• Power loop-thru cable (VN-38-PL)
• 1 m RS-232 daisy chain cable with RJ45
connections at each end (VN-38-RL)
• 10 m RS-232 host computer cable with
RJ45 connections (VN-38-S-232)
• 9-pin D-sub-to-RJ45 adapter (VN-38-RA)
• Service Manual (VN-38-SM; available
after 31 August 1999)
You will have to supply the hardware to install
the rails on the wall and the tools for this
hardware. For the display, you won’t need any
special tools. If the thumb screws and tight, you
can use a coin to loosen them.
About this manual: You will find some
information repeated in several places. This is
done on purpose. However, the explanation of
how to remove the screen is too long to repeat
every time it is needed; it is given once. The
serial number is located on the back panel and
again in the lower cable channel.
