REMOVING THE CONNECTOR CIRCUIT BOARD ASSEMBLY
Before beginning any service work, remove all power to the unit and disconnect any signal cables where necessary. The
rotating connector module must be set for desk top operation to gain access to the cover screws. It is not necessary to
disconnect the connector module from the main unit. Service work is best carried out with the unit inverted on a clean
work surface suitably covered to protect the mixer cosmetics. Ensure adequate lighting and use the correct tools. Access
to the connector circuit board options can be achieved without the complete removal of the circuit board.
