FACTORY CHECKOUT AND REPAIR
If it is determined that a problem exists within the
SCRB-68, it can be returned to the factory for checkout
and repair. Before returning the unit, contact the Min-

Authorization number (RGA#). This will ensure the
timely return of the repaired unit.
When returning a unit to the factory for repair, make
certain it is carefully packaged to protect it from dam-
age during shipment. Include, with the unit, the RGA#,
a description of the problem(s) encountered and the
serial number of the press on which it is used. Also
include your purchase order covering the work to be
performed and any special shipping instructions con-
cerning return of the unit.
