MAINTENANCE

There are no user-serviceable parts except for the fuses. If the transformer in the unit does not work properly, the entire power supply needs to be returned to the factory for repair. Refer to the Warranty and Return Information section of this manual for instructions on returning the power supply for repair.

Clean the outer surface of the power supply with a nonabrasive cleaning cloth and anti-static cleaner. Do not use kerosene or similar substances that may damage the surface.
