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.
