(1) Tuning voltage
Confirm the voltages in the table below at TP101. If the voltages are not satisfied,
replace T101 and
7103 for MW, T102 and T104 for LW or FE101 for FM.

Receive a broadcast by using the function of 'AUTO STOP'.
Adjust T105 (detector coil) so that the voltage at TP102 becomes 0£1.5mV.
(T106 is used to minimize the distortion of output on the production line.)
(3) FM separation
Receive a stereo signal.
Adjust VR 167 so that channel separation becomes maximam.
(4) MW Tracking
Adjust T101 (antenna coil) to obtain the best receiving sensitivity on 600kHz or
603kHz.
Adjust TC105 (antenna trimmer) to obtain the best receiving sensitivity on 1400kHz or
1404kHz.
(5) LW Tracking
Adjust T102 (antenna coil) to obtain the best receiving sensitivity on 164kHz.
Adjust TC106 (antenna trimmer) to obtain the best receiving sensitivity on Sodki{z or Z40ktiz,
