1. Safety Information for This Machine

• 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.

• Be sure to always use a dedicated replacement lamp that is new when replacing the lamp. If

you use a lamp that is not dedicated, it may result in an explosion and injury.
