between it and walls and other devices in order to allow good heat dissipation. If you put it in a rack, for example, leave at least 5 cm (2") open above it and at least 10 cm (4") open behind it. Failure to provide these gaps could cause heat to build up inside and result in fire.
o Place the unit in a stable location near the audio system that you
will use with it.
o DO NOT place anything, not even CDs, CD-Rs, LP records or cas-
sette tapes, on top of the units. Doing so could cause damage.
o The voltage supplied to the unit should match the voltage
printed on the rear panel. If you are in any doubt regarding this
matter, consult an electrician. o Do not move the unit during use. o Do not open the body of the unit because this could result in
damage to the circuitry or cause electric shock. If a foreign object
should enter the unit, contact your dealer. o When removing the power plug from the wall outlet, always pull
directly on the plug; never yank on the cord.
