Sec 3.0 Removing the Circle 5A's
active module from the cabinet
It is absoluletely essential that before removing
the module you have the necessary tools, a
clear space, and sufficient uninterrupted time to
work. Rushing leads to mistakes, and mistekes
can be dangerous and impair the excellent
performance of your Circle 5A speakers.
An isolated mains PSU is essential for your
electrical safety: be sure you never work on
equipment directly connected to the mains sup-
ply. Ensure that the mains supply is discon-
nected
and removed from the module, and is not
reconnected until the module has been fully
refitted.
We suggest that you cover your work bench
with a soft material to protect the underside of
your Circle 5A's from scuffing during
removal/replacement of the module. Also be
aware that the module is heavy and that once
the screws are loosened, it will tend to drop
downwards, and that the heavy aluminium
panel of the module will readily chip the softer
wood of the cabinet, exposing the white MDF
board under the black paint. You will need two
screwdrivers:
3.1: A 3.0mm cross head screwdriver of the
'Superscrew' or 'Pozidrive' NOT Phillips type.
The Superscrew type has 4 thin grooves into
which the Superscrew screw driver securely
locates. If the Phillips type is used, the screw-
driver will 'mash' the heads, and then it may
not be possible to remove the module from the
cabinet.
3.2: A larger size (M4, 4mm, No.2)
';Superscrew' or 'Pozidrive' screwdriver.
Section 3.3: Removing the screws
Please follow these instructions exactly. Failure
to do so may well destroy your cabinet and/or
module.
NB: This photo is of the earlier module,
but the screw arrangement is identical
First, using your smaller Superscrew driver,
check that the screwdriver makes a positive fit
to the screws marked 1,2,3,4. Applying as little
force as necessary, unscrew (anti-clockwise)
the four corner machine screws in the order 1,
2, 3, 4.
These screws locate in metal inserts trapped in
the inside of tha cabinet, and the alignment of
the module and the cabinet is precise.
Then, using the larger screw driver, remove the
screws A, B, C, D, E and, as you loosed screw
F, expect the module to drop down. Be ready
tocatch it!
The module can then be removed a short
distance from the cabinet, as the internal con-
nections to the module are on short flexible
wires. Be ready to carefully note the colour
coding and position of the wires that connect
the module to the woofer, tweeter and LED's.
