WARNINGS:

 

Lamp

Dispose of the used lamp according to local regu-

 

 

lations.

 

 

Since the lamp is made of glass, do not drop the

 

 

unit and do not scratch the glass.

 

 

Do not reuse the old lamp. This could cause the

 

 

lamp to explode.

 

 

If it is probable that the lamp has exploded (you

 

 

have heard an explosive sound), disconnect the

 

 

power plug from the power outlet and ask your

 

 

dealer to replace the lamp. The lamp is protected

 

 

by a cover glass, but in rare cases the reflector

 

 

and the inside of the projector could be damaged

 

 

by broken or shattered glass. Broken pieces of

 

 

glass could cause injury.

Reflector

Front Glass

Do not use the projector with the lamp’s front

glass covering removed.

 

 

Lamp Life

Projector lamps have a finite life. The projected images will become darker and hues will become weaker after a lamp has been used for a long period of time.

The LAMP indicator also becomes red when the lamp unit reaches a high temperature. Before replacing the lamp, switch the POWER OFF, wait approximately 20 minutes, then switch the POWER ON again. If the LAMP indicator still displays red, replace the lamp.
