9. Maintenance This chapter explains the operating precautions and maintenance for the projector. Operating Precautions • 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 either you are 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. Pay attention to the following points when using the projector: • What to do if a lamp has exploded • If the lamp explodes, remove the power cord from the projector, leave the room while making sure it is thoroughly ventilated. • If the lamp explodes and you think that you have gotten glass particles or mercury vapor in your eyes or have inhaled either, contact a doctor immediately. • Clean up the area around the projector completely while being careful not to get injured from any broken glass pieces. • Throw away any food that was near the projector. • Ask your service representative to replace the lamp and inspect the projector. • What to do if a battery has leaked • If leakage from a battery adheres to your skin, rinse it with water immediately, and then contact a doctor. • Wipe off the leakage with tissue paper while being careful not to touch it. 153
