the neighborhood to a good living environment.
[General cautions]
Cleaning the cabinet.
•Since many plastic materials are used on the
surface of the cabinet, if the surface is cleaned
using benzene, thinner, etc., it may change in
quality or the coating may be peeled off.  Avoid
using chemicals.
•When a chemically-teated cloth is used, follow
the cautions that come with the cloth.
•Do not spray a volatile agent such as
insecticide on the unit. Do not leave a rubber
or vinyl object touching the cabinet for a long
time. It may cause the cabinet to change in
quality or the coating to peel off.
•Clean the dirt from the cabinet and operation
panel by dusting lightly with a soft cloth.  If
the dirt is conspicuous, wipe off with a cloth
moistened with detergent diluted with water,
then wipe off with a dry soft cloth.
Rest your eyes occasionally when
viewing for a long time.
Caution when replacing the lamp.
•When replacing the lamp, turn off the power of
the projector and disconnect the power plug
from the power outlet.  Then wait for
45 minutes to allow the lamp cool:

not apply shock to it and do not
scratch it. 
•Also, do not use old lamp.  This could also cause
explosion of the lamp.
•If it is probable that the lamp has exploded
(explosive sound is heard), disconnect the power
plug from the power outlet and ask your dealer
to replace lamp.  
•In rare cases, the reflector and the inside of the
projector may be damaged by scattered broken
pieces of glass, and broken pieces could cause
injury when being handled
.
•When the lamp has been replaced, reset the
accumulated operation time of the lamp. 
•Do not reset if the lamp has not been replaced.
