M.15.5.1 Initialize Setting Guide - Initialize User Memory

[Start]. Please be careful as you cannot stop initialization after it's started.
Do not turn OFF the power switch while initialization is in progress.

The Backup SRAM data (Internal User Memory data when using GP-4100 series) is also deleted.

Initialization does not erase the SYSTEM SET UP, the SIO protocol, or the internal clock settings.

All data retained by the logic program is also erased.
