Frequency
Tuning a station having a known frequency. Connect TP501
and earth. Since the DFI will flash if the indication is incorrect, adjust VR501
so that the indi-
indication
cation matches the receiving frequency and the DFI stop flashing. After adjustment, disconnect TP501
and earth.

Connect the power supply to the set and switch ON. Connect the digital voltmeter
to TP403
and adjust VR401
to obtain
8.0V.
Next,
connect
the
digital voltmeter to TP404 and adjust VR402 to obtain 1.2V.
