Verifying Board Version - Furuno FS-1575 Service Manual

2. Verifying Board Version

The "VERSION (1/2)" and "VERSION (2/2)" windows displays board versions. When
turning ON the power supply, T-CPU will load the versions.
Even if there is a discrepancy in the combination of a board version and program, the
board version control allows for verifying the board version to be used to run the
program and achieve operation corresponding to the board.
