Reporting
Lamp Lamp
Withstands ambient temperatures up to
45˚C, and protects against dust problems.
The user is alerted instantly if an
operating problem should occur.
A new filter in the air intake section traps dust
particles that are 10 microns*
1 or larger. By
capturing approximately 7 times* 2 as much
dust as our previous filters, it guards against
optical blocks and
reduces the penetration
of dust into to the interior
to provide stable operation
by, for example, preventing
drops in brightness.
*1 10-micron dust = lint, pollen, etc.

Airflow Sensor
Temperature Sensors
An airflow sensor has been added to the air
intake section to quickly detect reductions in
the intake airflow due to a clogged filter or other
reasons. Also, a temperature sensor has been
mounted to the exhaust section in addition to
the existing ones at the air intake section and
DLP™ chip.
Warning LED and On-Screen Display
The projector body is equipped with a
temperature alarm LED and a burnt lamp (for
lamp 1/lamp 2) alarm LED. Information on the
location of the error is also given in the on-
screen display.
Dual Lamp System
Optional Long-Life Lamp
A long-life lamp that stretches lamp life to 4 000
hours is available as an option. In single lamp
operation mode, the lamp relay function allows
non-stop operation 24 hours a day for up to 47
weeks without replacing the lamps. The use of
UHM™ lamps dramatically cuts operating costs.
*The brightness of the long-life lamp is half that of the
normal lamp.
Liquid-cooling System
Panasonic’s original liquid-cooling system
directly cools the DLP™ chip, which extends
the PT-DW5000E/DW5000EL’s performances
and attains a high level of reliability.
Dust-Tight Cover
The lens unit opening is
fitted with rubber sealing.
New Cooling Structure
In order to further enhance the cooling
efficiency, we completely revised the
placement of various internal components and
combined this with our popular cooling system
to enable use in temperatures up to 45˚C. This
allows use in a wider variety of environments,
and keeps the operation more stable even in
harsh conditions.
Dustproof Design
with Sealed Optical Block
The effect of dust has been minimised by
completely sealing the optical block.The dust-
free design helps ensure that this DLP™
projector will continue to deliver crisp, sharp,
high-resolution images over an extended
service life.

Monitoring
A more powerful sensing performance
predicts problems with high accuracy.
Web Browser Control/
Monitoring and E-mail Message Alert
Anybody can operate the PT-DW5000E/DW5000EL
by remote control or monitor its status over a LAN
network, because it is all done using the computer’s
familiar Web browser. Furthermore, the PT-
DW5000E/DW5000EL sends an E-mail message to
notify the operator when an error has occurred, or a
lamp needs to be replaced.

The use of the two lamp systems increases brightness
and eliminates the
need to interrupt a
presentation if a lamp
burns out (in dual
lamp operation mode).
