tion or electric shock.
Power supply
• Before connecting this unit to other devices,
turn off the power to all units; this will help
prevent damage or malfunction.
• Be sure to set the POWER switch on the rear
panel according to the power source you are
using (adapter or USB).
• Do not use this unit on the same power circuit
with any device that will generate line noise,
such as an electric motor or variable lighting
system.
• The power requirement for this unit is indicated
next to the DC IN connector (rear panel) as
well as on the adapter’s nameplate. Be sure that
the outlet you choose meets this requirement.
• Avoid damaging the adapter’s power cord: do
not step on it, place heavy objects on it, etc.
• When disconnecting the AC adapter from the
power outlet, grasp the plug itself; never pull on
the cord.
• If the unit is to remain unused for an extended
period of time, unplug the adapter.

extremes (e.g., direct sunlight in an enclosed

dusty or humid areas, or areas that are subject
to high levels of vibration.
• Using the unit near power amplifiers (or other
equipment containing large power transform-
ers) may induce hum.

dry cloth or one that has been slightly damp-
ened with water. To remove stubborn dirt, use a
mild, non-abrasive detergent. Afterwards, be
sure to wipe the unit thoroughly with a soft, dry
cloth.
• Never use benzene, thinners, alcohol or solvents
of any kind, to avoid the possibility of discol-
oration and/or deformation.

sult with qualified service personnel.
