To clean this unit, use a soft, dry cloth.
For very dirty surfaces, dip a soft cloth in a weak soap-and-water
solution and wring well. After cleaning, wipe with a soft, dry cloth.

Notes:
1. Specifications are subject to change without notice.
Weight and dimensions are approximate.
2. Total harmonic distortion is measured by the digital spectrum
analyzer.
Never use alcohol, paint thinner, benzine, or a chemically treated
cloth to clean this unit.
Such chemicals may damage the unit's finish.
