Decoder
The air intake filter of the SDDS decoder must be kept clean at all times to avoid
that clogging stops the airflow.
Open the front panel of the DFP-2000 decoder and remove the air filter in the front panel
door, clean it and re-insert it.
How often this must be done depends on the density of dust in the air in your projection
room.
A clean working environment will contribute to making this procedure necessary on a
quarterly basis only.
