3)Installing procedure of commercially available metal fixture

Washers M8 (φ 25) are supplied to use together with com- mercially available metal fixtures.

•Fix commercially available metal fixture at either position of mounting holes for commercially available metal fixture at the

center or bottom of the rear side of the speakers with two bolts. Since there is a difference in step between these two mounting holes, the washer is used to diminish that difference.

W a s h e r M8 (φ 25)

Fix the fixture by two bolts at either position. Use the washer for lower mounting hole to com- pensate the difference in step between two holes.

•Make sure that the end of the cord is securely connected with the terminals by lightly pulling the cord after connection. Incomplete connection may cause broken sound or noise.

•If the cord wiring sticks out and the positive and negative wires short, the stereo amplifier will be subjected to an excessive load, and operation may stop or a malfunction may occur.

•When wrong polarity (+, -) of either speaker system (right or left) is connected to the stereo amplifier, proper stereo effects may not be obtained due to insufficient bass or loss of sound orientation feeling.

4)Cleaning the cabinet

•Lightly wipe off dust or dirt by a polishing cloth or a dry cloth.

•If the cabinet is very dirty, clean off the dirt using a soft cloth dipped in a neutral cleanser diluted 5 - 6 times, then wipe off any moisture using a dry cloth. Do not use a furniture wax or cleaner because it may dissolve or discolor the surface.

•Note that the surface may be dissolved or discolored when thinner, benzene, or spray type insecticide is stuck there.

•If using a chemically impregnated cloth, take care to observe the caution notices applying to use of the cloth.
