▀■ Warning-  To reduce the risk of fi  re or electric shock, do not  
expose this projector to rain or moisture.
▀■ Warning-  Please do not open or disassemble the projector & 
box as this may cause electric shock.
▀■ Warning-  When replacing the lamp, please allow unit to cool  
down, and follow all replacement instructions. See 
page 59.
▀■ Warning-  This projector will detect the life of the lamp itself.   
Please be sure to change the lamp when it shows 
warning messages.
▀■  Warning-  Reset the “Lamp Reset” function from the on-screen  
display “System-->Projector-->Lamp” menu after 
replacing the lamp module (refer to page 46).
▀■ Warning-  When switching the projector off, please ensure the  
cooling cycle has been completed before disconnect-
ing power. Allow 90 seconds for the projector to 
cool down. 
▀■ Warning-  Do not use lens cap when projector is in operation.
▀■ Warning- When the lamp is approaching to the end of its life 
time, the message “Replacement suggested” will 
show on the screen. Please contact your local reseller

Eye Safety Warnings
▀■Avoid staring directly into the projector beam at all times.
▀■Minimize standing facing into the beam. Keep your back to 
the beam as much as possible.
▀■A stick or laser pointer is recommended to avoid the need for 
the user to enter the beam. 
▀■Ensure that projectors are located out of the line of sight from 
the screen to the audience; this ensures that, when presenters 
look at the audience, they do not also have to stare at the pro-
jector lamp. The best way to achieve this is by ceiling-mount-
ing rather than fl  oor or table-mounting the projector.
▀■When projector is used in a classroom, adequately supervise 
students when they are asked to point out something on the 
screen.
▀■In order to minimize the lamp power needed, use room blinds 
to reduce ambient light levels.

Recommendations
To unleash the performance of the HD81, it is best to input video 
content in its original form without any processing. This will utilize 
the full capabilities of the HD81 for de-interlacing, scaling and 
image enhancement. As an example, if a user has an HDMI DVD 
player capable of outputting the video signal in a 480i/576i digital 
format, we recommend feeding it directly to the HD81 without any 
processing by the DVD player. This will provide the HD81 with the 
original digital video stream and allow the HD81 to fully unleash its 
studio grade video processing.
In general, we recommend the following:
If possible, use digital output (DVD, D-VHS, DTV setup box, etc). If 
there is no digital output, use the component output terminals (YPbPr) 
with short and high-quality components cables.
If you are unsure of the quality of the internal de-interlacing or scaler 
of your video source, let HD81 do the processing by connecting to the 
interlaced component output.
If possible, leave out any extra video processing in your video source 
(DVD, D-VHS, and HDTV STB).
Some HDTV STB models have scaling conversion that will output 
1080i from a 720p format. Try to output 1080i in its native signal for-
mat and let HD81 perform deinterlacing and scaling.
Not all HDMI DVD players have a digital interlaced output 
(480i/576i). For these products, it is suggested that users try 480p/576p 
fi  rst, followed by 720p and 1080i. After viewing the full range of out-
put resolutions, the user can then judge which is the best image quality 
and set the HD81 for that resolution.
Many high-end analog output DVD players also come with high qual-
ity DAC with 12 or 14 bits of processing.
Again, the users should try setting their 480i/576i output to HD81 fi  rst.
HD81 has BNC connectors for component video input. If the user 
plans to use analog component to connect to their video source, for the 
best image quality, it is recommend using the BNC connectors.
For connecting to Laser Disc player or S-VHS deck, we suggest to use 
S-video output connection to connect to HD81.
It is best to have a separate power outlet for audio and video equip-
ment.
