3. Vary the "M01" bus data until the voltage to pin (39)

of IC3001 to become the value as stated below.

SETTING VOLTAGE

ADJ spec : 490±10mVrms

CHK spec: 490±20mVrms

Separation Adjustment

1. Input "SIGNAL 1" and vary the "M04" bus data to get

the minimun AC voltage to pin (39) of IC3001.

2. Input "SIGNAL 2" and vary the "M05" bus data to get

the minimun AC voltage to pin (39) of IC3001.

SIGNAL 1:

300Hz, 30% modulation, Lch only, NR-ON

SIGNAL 2: 3kHz, 30% modulation, Lch only, NR-ON

Note: SIGNAL 1 Adj. for widebando

SIGNAL 2 Adj. for spectral

Check the output of the speaker at the maximum

volume as stated below.

Confirmation spec:

ADJ spec: above 25 dB

CHK spec: above 20 dB
