Care and Maintenance of the System

Your M9500 monitors should give years of trouble-free service. Normally, the only routine maintenance will be cleaning. The grilles may be cleaned of dust gently with a vacuum cleaner using a brush attachment. If there should be stains on the grille, a soft bristle brush moistened with a dilute mixture of water and dishwashing detergent may be used. The same mixture may be used for cleaning the enclosure finish itself if it has become smudged.

As mentioned before, the 9-volt batteries in the dividing net- works will last perhaps as long as their normal shelf life. You may expect them to last at least 5 years. If the LED no longer lights, remove the acrylic door on the front of the network and replace them.
