installed and used in accordance with the instructions, may cause harmful interference
to radio communications.  However, there is no guarantee that interference will not
occur in a particular installation.  If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of the
following measures :
•Reorient or relocate the receiving  antenna. 
•Increase the separation between the equipment and receiver. 
•Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
The cable with the ferrite core provided with the projector must be used with this
equipment in order to comply with Class B limits in Subpart B of Part 15 of the FCC
rules.
Use of shielded cable is required to comply with class B limits in Subpart B of Part 15

SAFETY INSTRUCTIONS
LAMP HANDLING 
PRECAUTIONS
This projector uses a high-pressure mercury lamp which must be handled carefully and
properly as mentioned below.
• A lamp may explode with a loud sound or burn out due to a shock, scratch, or expiration of
lifetime.
• The lamp life may differ from lamp to lamp and according to the environment of use. There is
not guarantee of the same lifetime for each lamp. Some lamps may fail or terminate their life
in a shorter period of time than other similar lamps.
•  A lamp gradually becomes darker with time of use.
• If the projector indicates that the lamp should be replaced (i.e., the LAMP REPLACE indicator
lights up twice), chances of explosion become higher. Replace the lamp with a new one
immediately.
• Always keep your face away from the exhaust vent so that you do not suffer from the gas and
broken shards of the lamp.
IF A LAMP EXPLODES
If a lamp explodes, the gas and broken shards may scatter inside the projector
and they may come out of the exhaust vent. The gas contains toxic mercury.
Open windows and doors for ventilation. 
If you inhale the gas or the shards of the broken lamp enter your eyes or
mouth, consult the doctor immediately.
If a lamp explodes, its shards may scatter inside the projector. Ask the Canon
service representative to clean and check the inside of the projector and
replace the lamp.
DISPOSAL OF WASTE LAMP
Dispose of the mercury lamp of the projector according to the local regulation
just like the fluorescent lamp. 
CARRYING/TRANSPORTING THE 
PROJECTOR
This projector is a precision machine. Do not give a strong shock to the projector or turn it
down. 
Thoroughly read “Use Caution When Carrying or Transporting the Projector” below and install
the lens cap before carrying the projector. When transporting the projector by train or airplane,
use a highly crashworthy transport case.
Use Caution When Carrying or Transporting the Projector
The carrying bag is intended for protection from dust and scratches on the surface of the
cabinet, and it is not designed to protect the projector from external shocks. When carrying the
projector with it put in the carrying bag, do not give a shock to it, drop it, or place anything on it.
Do not transport the projector through a courier or transport service with the carrying bag. The
projector can damage.

SAFETY INSTRUCTIONS
INSTALLATION PRECAUTIONS
Ensure that the projector is installed with a minimum distance of 1 m (3.3) from its left,
right, rear, and top panels to the neighboring object such as a wall.
Pay Attention to Hot Air from Exhaust Vent
Hot air is exhausted from the exhaust vent. Do not place any object near the exhaust vent.
•Do not put any spray can near the vent. 
The internal pressure increases due to heat,
resulting in explosion.
•Do not put any metallic object. It may become
hot, resulting in an accident or injury. 
•Do not put anything such as a plant pot.
•Do not put anything that may deform or
deteriorate due to heat.
•Do not put an audience seat near the
exhaust vent.
Do not put anything that may deform or discolor due to heat on the projector. The area
around the exhaust vent and the cabinet above the exhaust vent become hot. Do not touch
these areas, or you may get burnt. Especially, keep children away from these areas.
Do Not Use in the Following Environments
Do not install the projector in a humid or dusty place or a place where there is much oily
smoke or cigarette smoke. Optical parts such as a lens and mirror are stained, resulting in
poor picture. 
Do not use the projector in a place where the temperature becomes very high or low.
  Operating temperature: +5
°C to +35°C    Storage temperature:  -10°C to +60°C
Pay Attention to Condensation
If the projector is carried from a cold place to a warm place or the room temperature is
raised rapidly, dew may form on the lens and mirror due to the moisture in the
atmosphere, resulting in a blurred picture. Wait until dew evaporates and a normal picture
is shown.
Install the Projector at Proper Position
Install the projector properly. Improper installation may cause troubles and accidents.
•Do not tilt the projector more than 20 
degrees above and below.
•Do not point the projector up.
•Do not point the projector down.
•Do not put the projector on either side.
 Do not tilt the projector more than 20 degrees above and below.

INSTALLING THE PROJECTOR
INSTALLING THE PROJECTOR
Determining the Distance to the Screen
The projected image size is determined by the distance between the projector lens and
the screen. 
Select the place where the desired image size is obtained according to the figure shown
below. 
The image size can be adjusted using the Zoom lever by the lens.
H1 and H2: H1 is the height of the screen from the intersection of optical axis and screen
surface, and H2 is the height of the intersection when an image is projected at right angle
to the screen.
•  Install the projector at the position where the projection distance is about 1.2 m (3.9) to
9.1 m (29.9). If the installation position is too close, the image is out of focus. If the
installation position is too far, the screen becomes dark.
•  The sizes in the above table have been obtained assuming that the aspect ratio is 4:3.
They may vary from the actual sizes depending on the type of the projected image.
For the relationship between the screen size and projection distance, see the table
on page 85.
