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.
