Unpacking Your Disappearing In-Wall Speakers

Please Inspect For Shipping Damage

Each loudspeaker leaves our plant in perfect condition. Any visible or concealed

damage most likely occurred in handling after it left our plant and should be reported

at once to your Definitive dealer or the delivery company that delivered your loud-

speaker. Please unpack your system carefully. Save all cartons and packing materials

in case you move or need to ship your system. Record the serial number found on

the back of the speakers, and on the carton, in this manual and save it for future

reference should your speaker need service. For your best protection, register your

Di Series products on-line at http://registration.definitivetech.com.
