Power outage support
R4000 to R4177 in the D2-230 (SZ-3) and R4000 to R4377 in the D2-240 (SZ-4) are non-volatile data registers.
If you replace this system with the D2-263, the data registers will not be retained during a power outage.
If you are using this area, install a battery in the D2-263 and set the power outage retention area.
(This is not necessary if replacing with the D2-265)
