MTS ADJUSTMENT
(Only for Models 26SL70, 29SL80) MTS Level Adjustment
1. Feed the following monaural signal to pin (14) of IC3001. Monaural signal : 300 Hz, 245 mVrms 2. Connect the rms voltmeter to pin (39) of IC3001. 3. Enter the service mode and select the service adjustment "M01". 4. Adjust the data so that the rms voltmeter reads 490 ± 10 mVrms.
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 ± 0.75 kHz.
Filter Adjustment
1. Feed the following stereo pilot signal to pin (14) of IC3001 . Stereo pilot signal: 9.4 kHz, 600 mVrms. 2. Enter the service mode and select the service adjustment "M03". 3. Adjust the data at the point where "OK" appears on the screen. The "OK" represents the approximate center of the adjustable range of the data.
Separation Adjustment
1. Connect the rms voltmeter to pin (39) of IC3001. 2. Receive the following composite stereo signal 1. Composite stereo signal: 30% modulation, left channel only, noise reduction on, 300 Hz 3. Enter the service mode and select the service adjustment "M04". 4. Adjust the data until the AC voltage reading of the rms voltmeter is minimum. 5. Receive the following composite stereo signal 2. Stereo signal: 30% modulation, left channel only, noise reduction on, 3 kHz 6. Enter the service mode and select the service adjustment "M05". 7. Adjust the data until the AC voltage reading of the rms voltmeter is minimum. 8. Take the above steps 1 thru 7 again for fine adjustment.
