m DIAL CORD INSTALLATION GUIDE
For threading a fresh cord, proceed as follows.
1. Prepare a fresh cord more than 180 cm (70-15/16"')
in length.
2. Bring the variable capacitor into a state where the
drum is completely turned to the right (maximum
capacity and lowest frequency for the variable
Capacitor). Tuning shaft
. Direct the cord in the order from 1 to 8.
4. Stretch the cord in such a tension as the spring length
is elongated by 1.5 times that of the original state.
5. Fix the knot of the cord with the bond.

7. $8: Power switch in ‘‘on” position.
8. Indicated voltage values are the standard values for the unit 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.
* Figures in (_____}stand for DC voltage in FM/AM signal reception mode.
* Figures in<¢ »stand for DC voltage in FM stereo signal reception mode.
* Figuresin’ _sstand for DC voltage in FM (no signal) muting to on mode.
* Figures in ( stand for DC voltage with the band selectors circuit set at AM.

Shorting Switch
This unit uses a shorting switch. As illustated below, the circuit is shorted
to the next circuit without being opened.
In the circuit diagram, the shaded area represents the common terminal.
