CARE AND MAINTENANCE
CLEANING
The durable finish of the knobs and heavy aluminum
front panel will last indefinitely with proper care and
cleaning. Never use scouring pads, steel wool, scour-
ing powders, or harsh chemical agents, such as lye
solution. These will mar the finish. Clean with a soft,
lint-free cloth or cotton swab slightly dampened with a
mild solution of detergent and water.
REPACKING FOR SHIPMENT
Should it become necessary to ship your M-03 for any
reason, use the original packing materials. If these are
no longer available, be sure that adequate materials,
at least equivalent to the original, are used.
REPAIRS
Only the most competent and qualified service techni-
cians should be allowed to service the M-03. The
Luxman company and its factory-trained warranty
station personnel have the knowledge and special
equipment needed for repair and calibration of this
precision instrument.
Ventilation is very important for this high-power
amplifier, air should circulate freely around the back,
under and over the top of the case.
The amplifier has a built-in thermal overload protec-
tion circuit to protect against overheating. If internal
temperatures rise abnormally during continued
operation at a high volume level, the amplifier will
silence itself and the PEAK POWERLEVELINDICATOR
goes off. If this happens, check to be sure the ampli-
fier has enough space around it (more than 10 cm
over the top) and nothing is placed over the
ventilation holes of the amplifier. If not, correct it. It
may take a few minutes for the unit to cool down and
come back on. When the unit is cooled down, the
PEAK POWER LEVEL INDICATOR will light again to
indicate the amplifier is operative.
