Check the product carefully.

damage immediately by calling your dealer
and/or the shipping company that deliv-
ered it.
2. Connections: Whenever changing, con-
necting or disconnecting signal or power
cables etc., always turn off all equipment.
This prevents transients from entering the
equipment and prevents electrical energy
from reaching you. Keep all connections
out of the reach of children. Before moving
the unit, be certain to disconnect any
interconnection cords with other compo-
nents, and make certain that you discon-
nect any powered units from the AC outlet.
