2.1.1. Safety
precautions
•
A high-pressure mercury lamp is used as the light source of this product. 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 a removed lamp or do not lift it above your face. You may be injured in your
eye by flying or falling glass fragments.
•
The lamp gets very hot during operation. Do not replace the lamp immediately after
operation because you may get burned or injured.

, be sure to turn off the main power switch and unplug the power cord from the wall
outlet before replacing the lamp. And wait at least one hour to allow the lamp to cool down
enough to the touch. Lamp replacement without turning off the main power may result in
electric shock.
•
Replace the lamp with drawing on thick gloves. The lamp is heated for a while even if the
lamp is turned off.
•
Insert the lamp firmly. When the lamp isn’t installed properly, it won’t illuminate. Improper
installation may result in fire.
•
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 remove screws other than specified. Removal of unspecified screws may result in a
failure.
•
Do not put metals or flammable objects into the product. Using the product with any foreign
objects inside may result in electric shock or fire.
