MC-1600 Oiled Walnut Speaker System (400-1989) Care and Maintenance Faxback Doc. # 32804 PROTECTING YOUR INVESTMENT The speaker cabinet and grille require periodic maintenance for maximum appearance and performance. The enclosure is made of particle board, laminated with fine furniture-quality walnut veneer. Treat the enclosure as you would any fine piece of furniture. Don't place objects on top of the enclosure - this may mar the finish. To protect and enhance the fine wood finish, we recommend using a lemon oil furniture polish. Periodically clean the grille assemblies using a feather duster to remove accumulated dust. Do not use a vacuum cleaner unless you first remove the grille assembly from the cabinet. (The grille can be removed by gently grasping the corners of the assembly and pulling.) Never vacuum the actual speaker elements - use a feather duster, gently and sparingly. (YO/EB 5/3/96)
