This will not apply if the following two conditions are fullled.
g The [PROJECTOR SETUP] menu → [OPERATION SETTING] → [OPERATING MODE] is set to anything
other than [HIGH].
g The [PROJECTOR SETUP] menu → [FILTER SETTING] → [FILTER TYPE] is set to [LONG LIFE].
Attention
f Make sure to turn off the power before performing maintenance of the filter.
f Make sure that the projector is stable, and perform the maintenance in a safe place even if the lter falls accidentally.
Note
f The runtime of the lter can be checked in the [PROJECTOR SETUP] menu → [STATUS] → [FILTER COUNTER].
f Air lter replacement is recommended after cleaning the unit two times.
f The dust-proof properties may be reduced after each cleaning.
f The time until clogging of the air filter unit varies greatly depending on the usage environment.
f The Smoke Cut Filter (Model No.: ET-SFR330) cannot be reused by performing maintenance. Replace with new one.
