Note (1): For SU20KX, SU40KX and SU40K models, wire #11 is connected between P board (CNP8) and FA (CNA9) for bypass input. (See chapter
1.5.) For SU60KX, SU80KX, SU60K, SU80K, SU60KTV and SU80KTV, wire #11 is connected between P board (CNP8) and F1 (CNF15) for bypass
input. (For locations, see chapter 1.7)
Note (2): To learn about EEPROM parameter settings and calibration, turn to chapter 3.2.
Note (3): For the location of the NHS-SYS-P and NHS-SYS-M boards, turn to chapter 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.
