YM-4600A/4100A Only

5-2. As YM-4600A/4100A does not have a resonance regulator, insert resonators into resonator holders

as shown below.

* The resonators are factory adjusted so that the optimum resonance level is

obtained at 23°C. If desirable resonance is not available due to the

temperature lower or higher than 23°C, adjust setting of the resonators.

Move the resonators to fit into longer grooves when the temperature is higher

and into shorter grooves when the temperature is lower.

Temperature

("A" in the figure right)

Adjust the height of the tone bars.

While supporting the frame end of the leg by hand, loosen the fixing bolt of the slide guide on both large

end and small end sides.

Adjust the height to the desired level and tighten the fixing bolts securely.

When adjusting the height, use the lines on the slide guide for reference and make the tone bars in

parallel with the floor surface.

Upon completion of assembly, check to make sure that each bolt is tightened securely.
