CARE AND CLEANING
Under normal use, the amplifier will not require any special care. Over time you may wish to clean the exterior of
the unit by wiping it with a damp cloth to remove any dirt or dust that accumulates on it. Unplug the amplifier and
be sure that it has completely powered down before you apply any damp cloth. Do not let any liquid enter the
amplifier through the vents in the top cover. REMEMBER, LIQUIDS CONDUCT ELECTRICITY!!! You may clean
the connectors on the back panel with isopropyl alcohol annually.
