Note (1): Wire #31 connects CNP10 on the NH-SYS-P board to CNB7 on the NH-SYS-B board (Figure 5.2.11b).

Note (2): To learn about EEPROM parameter settings and calibration, turn to section 3.2.

Note (3): For the location of the NH-SYS-P and/or NH-SYS-M board, turn to section 1.5. To replace the NHS-SYS-M board, remove the EEPROM chip from the old NHS-SYS-M board and insert it into the new one.
