Images are projected onto an 80-inch wide
screen with a projection distance of 0.86 m.
Close range projection reduces not only shadows of the presenter but also 
glare of the projection light, making lectures and meetings less stressful.
Projecting images onto a large screen in a limited space; making lectures go 
smoothly by eliminating glare of the projection light and the shadow on the screen.
The new short-throw interactive projectors meet these needs, creating new styles 
of lectures, workshops, meetings and presentations.
The interactive function allows 
writing on a projected image.*1
You can write letters or draw fi gures on the projected image with an interactive 
pen. Then you can store these letters and fi gures in a computer. 
The interactive function allows effi cient and effective presentations and 
promotes information sharing.
You can write notes and points on the screen with the interactive pen/pointer.
During presentation, you can use the whiteboard to operate the computer.
You can instantly store and share with others the decisions made during meetings.
The teacher makes the students write answers on the 
whiteboard to increase their feelings of involvement in 
the class and their levels of understanding.
The presenter writes key points and new data on the 
whiteboard in real time to conduct realistic training.You can immediately digitalize the contents written on 
the screen for information sharing.
Projection and writing on a large screen make 
presentations more compelling.

							High Brightness of 2,500 lm and a 10 W High-output 
Speaker Meet Your Meeting/Seminar Room Needs.
High brightness of 2,500 lm ensures bright and easy-to-see image projection. 
The volume level of the 10 W high-output speaker is enough for meeting 
rooms and classrooms; you do not need to use an external speaker. You can 
make multi-media presentations (including audio presentations).
0.42 W Standby Power Consumption*5
When Standby mode is set to Eco, the standby power consumptions is as low 
as 0.42 W *5, reducing running cost and effects on the environment.
Lamp and Air Filter Replacement Cycle of Up to 4,000 Hours
The lamp replacement cycle of up 
to 4,000 hours*2. The air fi lter is 
constructed of three layers with 
different mesh sizes. The air fi lter 
replacement cycle is also 4,000 
hours*
3. Such replacement cycles 
reduce maintenance hassles, 
because longer periods of use 
translate to lower maintenance 
costs and environmental impact.
Quiet 29-dB*4 Design Does Not Interrupt 
Meetings or Classes
As the quiet design keeps noise levels down to 29-dB*4, the sound of the 
cooling fan is hardly noticeable. The audience can concentrate on the 
presentation and the screen images even during quiet scenes.
Extensive Interfaces with an HDMI Input Terminal
Extensive interfaces,  including two sets of computer (RGB) input terminals 
(one set is switchable to output.) and an HDMI input terminal, allows a wide 
range of system confi gurations.
Easy to Replace the Lamp and Air Filters
You can replace the lamp from the top  
and the air fi lters from the back of the 
projector. There is no need to detach 
the projector from the ceiling bracket.
Wireless Remote Control is Convenient 
When Using More Than One Projector.
A maximum of six IDs can be set up, allowing individual remote 
control of several projectors.
Easy Remote Monitoring and Control
Web browsers of computers connected via wired LAN allow you to remotely 
operate the projector and check its status. The email messaging function lets 
you know when to replace the lamp, and notifi es you of the projector status. 
Multi Projector Monitoring and Control Software is available to monitor and 
control multiple Panasonic projectors using a single computer. The wired LAN 
terminal is compatible with PJLink
TM (class 1). The open protocol that is used 
by many manufacturer ensures control of system confi gurations which include  
projectors of other manufacturers.

Startup Logo Function*6 is Effective for 
Theft Prevention
To start projection, you can display your pre-registered logo. Displaying your 
school or company logo aids in theft prevention. The password function 
prevents unauthorized use of the projector.
“Direct Power Off” Right after Use
The breaker in the room is directly turned off without operating the power 
switch of the ceiling-mounted projector. You can leave the room immediately 
after the meeting or the class.

Speci cations
Do not install the projector in locations that are subject to excessive water, humidity, steam or oily smoke. Doing so may result in fi re, malfunction or electric shock.
Caution
1  The projector uses a high-voltage mercury lamp under high internal pressure. This lamp may break, emitting a popping 
sound, or fail to illuminate, due to impact or extended use.
2  The high-wattage lamp becomes very hot during operation. Please observe the following precautions:
  • Never place objects on top of the projector while it is in operation.  
  • Make sure there is an unobstructed space of 500 mm (19-11/16 in) or more around the projector’s exhaust openings. 
  • If stacking projector units, care must be taken to provide the recommended space between units. These space 
requirements also apply to installation where only one projector unit is operating at one time and the other unit is used 
as a backup.    • If the projector is placed in a box or enclosure, the temperature of the air surrounding the projector must match the 
operating temperature listed in the specifi cations table during use. Also, make sure the projector’s intake and exhaust 
openings are not blocked.  Ensure there is suffi cient ventilation to prevent hot air from the exhaust openings being 
recirculated into the intake opening.
3  The lamp replacement cycle duration becomes shorter if the projector is operated repeatedly for short periods.
  • The lamp replacement cycle varies greatly depending on individual lamp characteristics and usage conditions.
  • The brightness of the lamp will gradually decrease with use.
4  Due to natural characteristics of lamps, screen brightness may fl  uctuate. This is not an indication of faulty lamp performance.
