Component Removal
If there are no authorized service centers near you and your monitor(s) should
require repair, it may be necessary to ship the defective component to the nearest
repair center. In this event, it is highly recommended that the defective component
be removed from the enclosure and shipped separately. This will prevent the
possibility of freight damage to the enclosure.
Removing tlw Low frequency Transducer:
The LF transducer is mounted to the
baffle \viili four screws. Before attempting to remove the LF transducer from the
baffle, first lay the enclosure on its back. To gain access to the LF transducer,
remove the grille by carefully pulling it away from the baffle. A tight fitting grille
may require that you lift each comer a little bit at a time.
Remove the four screws which hold the component in place. The component
should easily lift out of the baffle. Disconnect the leads from the terminals.
Carefully package the component prior to shipping.
Removing the Midrange and High Frequency Dome;
These transducers are held
in place with four screws. It should be relatively easy to lift the transducers out of
their place on the baffle once these screws are removed. However, sometimes the
devices may appear glued in place and do not easily lift out. Tliis can happen when
painted surfaces are not completely dry and the pressure applied by the mounting
screws causes a slight bonding of surfaces. With a steady hand, use a sharp edged
tool (i.e. a knife) to lift the edge of the mounting flange away from the enclosure.
