Using the Adjustable Port System
The ALF40 features a unique port system which allows for great flexibility
in positioning and concealing the product.
The port can be switched between two optional positions in the ALF40’s
cabinet. An aluminium plate [port plate] and rubber o-ring provides an air-
tight seal around the port. A similar plate is used to cover the unused port
hole [blanking plate].
WARNING:
BE CAREFUL NOT TO DROP ANY OBJECT INTO THE ALF40
ENCLOSURE THROUGH THE PORT HOLES.
