1.1.3 Judging and reprogramming in case of redundant BP addresses
The BP unit of this system is provided with specific addresses in its production stage. These
addresses are used to conduct various controls. If by any chance (on 3 out of 260000 units)
these addresses are redundant, the system may get in trouble. When replacing the PCB of the
BP unit too, these addresses may be used repeatedly.
