. Set the frequency display to "108.0 MHz" and the FM
MODE switch to "MONO" position.
2. Confirm that there is noise with no input signal.
3. Confirm that the output of test point "TP101"
is
4.
8.0+2V.
Set the frequency display to "87.5MHz" and confirm
that the output of test point "TP101"

IF, Detection and MPX
FM detector coil :T105
1. Connect a center-meter or a digital voltmeter to test
point "TP102" , and tune toa 100.1 MHz signal (1kHz
modulation, 75kHz or 40kHz deviation) with SSG ATT
70dB.
. Adjust T105 so that the center-meter indicates "0" or
the digital voltmeter reads 0 + 1.5 mV.
