Attach the resonators.

3-1. Assemble the resonator pipes. Make sure that the natural tone and accidental tone sides

are properly assembled. All pipes on the natural tone side have bottoms attached.

3-1. First, lower the accidental resonator pipes from above the instrument between the frame

sections, and into the rubber resonator holder. Next set the natural tone resonator pipes in

the rubber resonator holder. Set the bass side of the resonator pipes into the center grooves

on the resonator holder. Make sure that the pipes are set between the tone bar posts.

* Make sure not to confuse the natural tone resonators and accidental tone resonators.

* Take care not to bump the resonators against the legs, etc.

* The resonators are factory adjusted so that the optimum resonance level is obtained at 23°C (73.4°F). If

desirable resonance is not available due to the temperature lower or higher than 23°C (73.4°F), adjust

setting of the resonators. Move the resonators to fit into shorter grooves when the temperature is higher and

into longer grooves when the temperature is lower.
