PROCEDURE METHOD MEASURING FIGURE
1. Connect the LINE OUT cords to the VTVM.
2. Place the set into the mode of program 1.
3. Play the test tape QZZVTT804 and measure
the output (original signal).
4. Changeover to program 2, play and measure
the output (crosstalk signal).
5. Read the ratio between original signal and
crosstalk signal in dB.
6. Adjustment should be repeated step 4, 5 and
6 above.
