CAUTION
NOTE Before beginning this step, very carefully seat the aluminium
top cover above the compact disc in its specially machined
recess and position, so that the two finger slots match the one on
the player main chassis. The slightly curved section of the finger
slots should be facing the front of the unit. This will give a more
accurate operational mass of the main chassis.
Do not attempt to lift the main chassis from the suspension
towers as this could damage the connecting cable between
the display module and the main chassis. If the main chassis needs to
be removed, a special technical document is available from Agence
Commerciale A.C.I. Inc. or your local area distributor. This work should
always be carried out by an experienced and competent technician.
• Place your Oracle CD player on a flat surface to complete the set up procedure.
Suspension Fine Tuning
The suspension of your Oracle CD turntable has been calibrated at the factory
but it possibly might require minor fine-tuning before putting the player into
service. To help with this we have supplied a suspension calibration tool to
assist with accurate measurement and calibration of each suspension tower.
NOTE The reference to clockwise or counter-clockwise is
determined by viewing the spring module from above.
Suspension Fine Tuning
The tool supplied will help you determine if a suspension
fine tuning is required. If no or only minor changes
need to be performed, you might select
to leave the system as is.
At this point, the suspension top covers
can be installed and the player moved to
its final playing location.
To complete the final leveling of the
plinth, it will be necessary to use a spirit
level. The leveling will be achieved by
ajusting the height of the threaded feet
under the plinth.
This picture indicates the target setting of the suspension system.

In the unlikely event that your Oracle suspension system
may need to be completely recalibrated please refer to
the caution on the preceeding page.
Make the Suspension Housing Sit Lower
Make the Suspension Housing Sit Higher
If the suspension housing is sitting to high as on this picture
• With one hand apply a
light down pressure to
the main chassis while
holding the suspension
housing
• Rotate the spring counter-clockwise by very small
increments until the suspension housing lightly
rests against the step on the gauge
If the suspension housing is sitting to low as on this picture
Do not allow the pliers to contact the aluminium parts since
this could damage the clear lacquer finish.
• Gently raise the
suspension
housing
with one
hand
• While holding the spring to prevent it from turning, rotate by very small increments
the suspension housing, couter-clockwise. This will move the spring further out of
the spring calibration sleeve thus making the suspension housing sit higher.
NOTE
IMPORTANT
•␣ When all suspension towers are fine tuned, install the suspension covers
Suspension Fine Tuning
To proceed with minor changes to the suspension
fine tuning, please read the following information.
• Using needle nose pliers, insert the tip
of the pliers near the end of the spring
and hold it firmly

NOTE To obtain optimal performance, keep the surface of the Ure-
thane vibration damping trap clean at all times using your
Brillance cleaner or denatured alcohol (methylated spirits).
To extend the cleaning cycle to a maximum, we recommend not setting the
magnetic disc clamp with the Urethane facing down as dust would very quickly
reduce the adhesion to the compact disc, thus lowering the vibration damping
trap efficiency.
CAUTION Since the adhesion will diminish as the Urethane picks up
dust, it is important to place your hand under the compact
disc to prevent it from falling.
Please read the recommended maintenance procedure below.
Operation
• Place the compact disc on your Oracle CD turntable
• Install the magnetic disc clamp
The Magnetic Disc Clamp
To Remove the Magnetic Disc Clamp
• Lift the compact disc
by holding it from the periphery
with the magnetic disc clamp
installed
RECOMMENDEDOption 1
CAUTIONOption 2
Maintenance
Your Oracle player is equipped with a very efficient magnetic clamp. One of the
key features of this clamp is the proprietary Urethane compound ring that acts
as a vibration damping trap.
• Peel the disc from the clamp, this will break the close seal between the
Urethane vibration damping trap and the compact disc
• Lift the magnetic disc clamp
straight up. The compact disc
will follow because of the adhesion
of the Urethane vibration damping
trap to the compact disc surface
