1.10.1. Safety precautions
•
Be sure to turn off the main power switch and unplug the power cord from the wall outlet
before replacing the lamp. Lamp replacement without turning off the main power may result
in electric shock.
•
Do not put metal or flammable object into the projector. Using the projector with any foreign
object inside may result in electric shock or fire.
•
Insert the lamp firmly. When the lamp isn't installed properly, it won't illuminate. Improper
installation may result in fire.
•
The lamp gets very hot during operation. Do not replace the lamp immediately after
operation because you may get burned or injured. Before replacing the lamp, turn off the
power to extinguish the lamp and wait about one minute for the cooling fan to stop. Then
turn off the main power switch, unplug the power cord from the wall outlet, and wait at least
one hour to allow the lamp to cool down enough to the touch.
•
Replace the lamp with drawing on thick glove. The lamp is heated for a while even if the
lamp is turned off.
•
A high-pressure mercury lamp is used as the light source of this projector. The high-pressure
mercury lamp can explode or fail to illuminate permanently because of an impact, scratch, or
deterioration through use. The period of time until explosion or permanent failure to
illuminate varies considerably from lamp to lamp depending on operation conditions, etc.
Therefore, the lamp may explode soon after you use it for the first time.
•
Do not shake the removed lamp or do not lift it above your face. You may be injured in your
eye by flying or falling glass fragments.
•
When you open the doors or lamp cover for the purpose of lamp replacement, do not touch
any parts inside that are not necessary for lamp replacement because you may get injured
or a failure may occur.
•
Do not open the doors for lamp replacement or lamp cover during operation. Unnecessary
opening of the doors may result in a failure.
•
Do not remove screws other than specified. Removal of unspecified screws may result in a
failure.
