Cleaning inside the projector
In certain environments, such as in dusty locations, dust accumulated around the intake and exhaust ports may degrade ventilation, cooling,
and heat venting, and brightness may decrease as a result.
If brightness is noticeably reduced and the light source does not turn on, ask your dealer to clean inside the projector or replace the light
source unit.
Inspection
Ask your dealer for inspection by an expert at least once every three years.
If the projector is used for prolonged periods without inspection, it may catch fire, cause an electric shock, or fall.
f For information about inspection costs, consult your dealer.
Attention
f Do not leave the product in place after use. Put it away immediately to prevent it falling in the event of an earthquake, etc.
