CARING FOR YOUR GFA-585se
Great care has been taken by ADCOM to assure that your amplifier is as flawless in
appearance as it is electronically. The front panel is a heavy- gauge, high-grade aluminum
extrusion carefully finished and anodized for durability. The chassis, top cover and rear panel
are of heavy-gauge steel, both painted and baked. If the front panel, top or sides should
become dusty or fingerprinted, they can be cleaned with a soft Iintless cloth, slightly
dampened with a very mild detergent solution or non-ammonia glass cleaner.
DO NOT SPRAY OR USE LIQUIDS OF ANY KIND ON THE SURFACES OF THE GFA-
585se. DO NOT EXPOSE THE AMPLIFIER TO RAIN, WATER OR MOISTURE OF ANY
KIND.
