INSTALLATION AND POSITION
This CD player should be positioned on a at stable surface. We would
recommend that the position of your hi- equipment should be chosen carefully
to provide adequate protection for this device, and also provide an attractive
showcase for your investment. Hi- equipment is not designed to be moved
often, therefore it is recommended that a permanent home for your hi- be
achieved as soon as possible.
This CD player contains sensitive electronic circuitry, it is not recommended
that audio equipment such as CD players, turntables or cassette decks be
placed immediately next to heavy electrical equipment which may interfere
with them. Do not place this product in areas of direct sunlight, nor place it
adjacent to a radiator or other heating appliances.
Like all electrical devices this tuner will generate a modest amount of heat.
The cooling of this device is reliant upon the ow of air through the case.
Care should be taken not to cover this unit with items such as rugs, covers or
curtains which will restrict this air ow, and may cause over heating.
Never allow the CD player to come into contact with water or liquids, and
ensure that small objects do not fall through the ventilation grilles. In the event
of this happening, disconnect the wall plug from the mains supply immediately,
and contact your local dealer for service advice.
Do not position the power cable where it can be walked upon, or damaged by
regular trafc. Ensure that all other interconnection cables are stowed safely
behind the unit, and cannot be easily snagged or kicked, thus causing damage
to the unit.
Ensure that all interconnection cables have been made correctly, and that
correct polarity has been maintained.
MAKING THE CONNECTIONS
It is necessary to connect this CD player to an external amplier and
loudspeaker set up, (it is not possible to connect loudspeakers directly to this
CD player). Connect a pair of phono cables (supplied) from the signal output
sockets on the rear of the SP 121 to the audio input sockets on the back of
your amplier.
