Using the Adjustable Port System
End/Side Positions
Important notes:
1. ALWAYS loosen the four screws in the
port plate before adjusting the port.
2. Blanking plates MUST always be
screwed down over the port openings
that are not in use.
3. Be sure to tighten both the port plate
and the blanking plates. Never over-
tighten the screws.
4. Use ONLY the supplied screws to fix
the port and blanking plates.
Contact your dealer if spares are
required.
5. Ensure the rubber o-ring is correctly
in position around the port and sitting
within the circular rebate.
6. To release the blanking plate from its
position, it may be necessary to push
it from behind from within the cabinet.
This can be done via the other port
opening once the port is removed.
These port positions can be useful when the ALF80 is located behind a kickboard, or
underneath a sofa.
DO NOT modify the length of the port by cutting it or extending it using additional
tubing or flexible pipes.
Doing so will seriously compromise the acoustic performance of the product.
