MTS ADJUSTMENT
MTS Level Adjustment
1. Set the sound volume above 1.
Monoral signal: 400Hz, 100% modulation
2. Confirm "M01" data is "09h".
3. Vary the "EX4" bus data until the voltage to pin (39)
of IC3001.
4. Become the value as stated below.
• Only for 32U-F810
1. Set the sound volume above 1.
2. Vary the "M06" bus data until the voltage to pin (39)
of IC3001.
3. Becomes the value as stated below.
SETTING VOLTAGE
ADJ spec : 490±10mVrms
CHK spec: 490±20mVrms
MTS VCO Adjustment
1. Keep the unit in no-signal state.
2. Connect the frequency counter to pin (39) of IC3001.
3. Connect a capacitor (100µF, 50V) in between
positive(+) side of C3005 and ground.
4. Enter the service mode and select the service
adjustment "M02"
5. Adjust the data so that the frequency counter reads
62.94 ±0.75kHz.
Filter Adjustment
1. Feed the following stereo pilot signal to pin (14) of
IC3001 .
Stereo pilot signal: 9.4kHz, 600mVrms.
2. Enter the service mode and select the service
adjustment "M03".
3. Adjust the data until "OK" appears in position on the
screen. Make sure the "OK" is displayed almost at
the center of the data range.
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
• Only for 32U-F810
1. Input "SIGNAL 1" and vary the “M07” bus data to get
the minimun AC voltage to pin (39) of IC3001.
2. Input "SIGNAL 2" and very the “M08” bus data to get
the minimun AC voltage to pin (39) of IC3001.
Note: SIGNAL 1 Adj. for wideband
SIGNAL 2 Adj. for spectral
