plugging this unit into the AC main supply. Voltages
are 110-120/220-240 V AC, 50/60 Hz.

designed to consume a very small quantity of power.

Taking care of the subwoofer
• When you wipe this unit, do not use chemical solvents
(e.g., alcohol or thinners, etc.): this might damage the
finish. Use a clean, dry cloth. For difficult soils,
dampen a soft cloth in water, wring it out, and then
wipe with the cloth.
• (For polish-finished model) Bumping the surface of
the instrument with metal, porcelain, or other hard
objects can cause the finish to crack or peel. Use
caution.
