Note (1): For SU20KX, SU40KX and SU40K models, wire #1 is connected between the P board (CNP7) and FA (CNA9) for main input. (See chap-
ter 1.5.) For SU60KX, SU80KX, SU60K, SU80K, SU60KTV and SU80KTV, wire #1 is connected between the P board (CNP7) and F1 (CNF15) for
main input. (See section 1.5.)
Note (2): To learn about EEPROM parameter settings and calibration, turn to section 3.2.
Note (3): For the location of the NHS-SYS-P and NHS-SYS-M boards, turn to section 1.5. To replace the NHS-SYS-M board, simply remove the
EEPROM chip from an old NHS-SYS-M board and insert it into the new one.
