Notes on safe operations
Initial setup
●Place the player in a location with adequate ventilation to prevent heat build-up in
the apparatus.
●Do not place the player on a soft surface such as a rug that might block the
ventilation holes on the bottom.
●Do not place the player in a location near heat sources, or in a place subject to direct
sunlight, excessive dust or mechanical shock.
Power requirements
● [ V AC, 50 / 60 Hz ]
POWER-CORD CAUTION
Handle the power cord by the plug. Do not pull out the plug by tugging the cord and
never touch the power cord when your hands are wet as this could cause a short
circuit or electric shock. Do not place the unit, a piece of furniture, etc., on the power
cord, or pinch the cord.
Never make a knot in the cord or tie it with other cords. The power cords should be
routed such that they are not likely to be stepped on. A damaged power cord can
cause fire or give you an electrical shock. Check the power cord time to time.
On repair
●Please consult our authorized dealer nearest to you.
Break-in
●Since a large amount of electrolytic capacitors are used for the DS Master3
equalizer, it takes time to break in.You can enjoy better sound by leaving the
power on for 24 hours after purchase for several months.
