I should start by breaking down the components. FSDSS586—maybe each letter stands for something. Let's see, "F" could be "Food," "Financial," "Fitness," "Fashion," etc. "SD" might be "Smart Device," "Software Development," "Support System," etc. "SS" could be "System," "Service," "Security," or "Software." Then "586" could be a model number, version, or a code. Without knowing the specific context, this is tricky.
