4. Measures to prevent pulling movement malfunctions in the TC case unit.

1.Model name: SF-2014/21 14/2214 Z-800, SN-1420/1430 (USA only)

2.General: TC case units with inferior pulling movement were produced due to variance in the assembly process when attaching the socket holder unit to the base plate. As a temporary measure to alleviate this problem, the assembly method for the socket holder unit had been controlled, but as a permanent measure the shape of the socket holder has been changed. In accordance with this change, and even if the control of the method of assembly is no longer carried out, the pulling motion malfunctions no longer occur.
