Signature 2.1

Cleaning

When the unit gets dirty, wipe it with a clean, soft and
dry cloth. If necessary, first wipe the surface with a soft
cloth slightly dampened with mild soapy water, followed
by a fresh cloth with clean water. Wipe immediately
with a dry cloth. Never use benzene, thinner, alcohol or
any other volatile cleaning agent. Do not use abrasive
cleaners, as they may damage the finish of metal parts.
Avoid spraying insecticide near the unit.

Moving the Unit

Before moving the unit, be certain to disconnect any
interconnection cords with other components, and make
certain that you disconnect the unit from the AC outlet.

When positioning the amplifier in its final location, make
certain that it has adequate ventilation on all sides, as
well as on the top and bottom. Do not place CDs, record
jackets, owner’s manuals or other paper on top of, or
beneath the unit, or in between multiple amplifiers in a
stack. This will block the air flow, causing degraded per-
formance and a possible fire hazard. If the unit is to be
enclosed in a cabinet or rack, make certain that there is
adequate air circulation, with means provided for hot air
to exit and for cool air to be brought in.

Typographic Conventions

In order to help you use this manual with the front panel
controls and rear panel connections, certain conventions

Unpacking and Installation

The carton and shipping materials used in protecting
your new amplifier were specially designed to cushion it
from the shocks and vibration of shipping. We suggest
that you save the carton and packing materials for use in
shipping if you move or if the unit ever needs repair.

To minimize the size of the carton in storage, you may
wish to flatten it. Carefully remove any staples used to
close carton seams; carefully slit the tape on the bottom
and collapse the carton. Other cardboard inserts may be
stored in the same manner. Packing materials that cannot
be collapsed should be saved along with the carton in a
plastic bag.
