: On/off switch in ‘’on"’ position.
: Record detector switch in ‘‘off’’ position.
(It is detects the record on the turn table.)
: Start switch in ‘‘off’’ position. (It is not pushed.)
: Stop switch in “off'’ position. (It is not pushed.)
: Cueing control switch in “off’’ position. (It is not pushed.)
: Repeat switch in ‘‘off” position. (It is not pushed.)
: Speed selector switch in “auto” position.
33 rom <— auto <— 45 rpm
: Rest switch in ‘‘off’’ position.
(Tonearm is off the rest position.)
: Record size detector switch in “‘on” position.
(17 cm record is on the turntable.)
: Cabinet switch in ‘‘on”’ position. (Upper cabinet is closed.)
: Voltage selector in ‘110 — 120V"' position.
110 — 120V<»220 — 240V
Indicated voltage values are the standard values for the measured by the DC
electronic circuit tester (high-impedance) with the chassis taken as standard.
Therefore, there may exist some errors in the voltage values, depending on
the internal impedance of the DC circuit tester or the set measured.
* [-~] is the voltage at 45 rpm.
