• Do not look into the projection window or vent when the machine is on. The bright light may
damage your eyes. Be especially careful in an environment with children.
• Do not stare at operating lamp. May be harmful to the eyes.
• Before replacing the lamp, turn off the power and wait at least one hour to allow the machine
to cool completely. If it is not completely cool, you may burn or injure yourself due to the inside
of the machine and lamp unit being hot. If you replace the lamp without unplugging the power
cord from the power outlet, electric shock or explosion may occur.
• Be careful when handling the used lamp so that it does not break. If it breaks, it may cause
injury.
• The machine's light uses a mercury vapor lamp that becomes high pressure when it is turned on.
The lamp has the following characteristics, so be sure to handle it with care after understanding
the contents. If the lamp explodes and you are either injured from broken pieces of glass, think
you have gotten glass particles or mercury vapour in your eyes, or have inhaled glass particles
or mercury vapour, contact a doctor immediately.
• Deterioration or shock can cause the lamp's life span to end or the lamp to explode. If the
lamp explodes, it may make a big noise.
• The time that it takes for the lamp to reach its life span or explode depends on each
individual lamp and its operating conditions. It is possible that it might explode the first
time it is used.
• If you use the lamp past its replacement period, the possibility of explosion increases.
• If the lamp explodes, broken glass pieces may be scattered around the inside of the
machine and ejected from the vent or other opening.
• If the lamp explodes, a very small amount of mercury vapor in the lamp tube and broken
glass pieces may be ejected from the vents or other opening.
• Do not block the projection light when it is on. If you do so, the part that is blocking the
projection light may get quite hot and deform, deteriorate or cause a burn or fire. The reflected
light may make the projection window hot and cause a machine failure. To temporarily
suspend projection, select the AV mute function. To suspend longer, turn off the machine.
