HOW TO STRING DIAL MECHANISM
After the dial string is properly installed
around the dial pointer and Tuning Control,
follow the procedure given below to hook it
around the outer groove of the double-groove
pulley attached to the variable capacitor.
Diagram shows the completed stringing.
1. String the outer groove from inside to
outside.
2. With the string so wound around the
pulley, fix its end to the screw.
3. Turn the Tuning control clockwise until it
begins to idle.
4. Using a finger, shift the string leading to
the screw toward inside of the same
outer groove.
5. Turn the Tuning Control to confirm that
the completed stringing is as shown in
the diagram.
