This manual introduces the Yamaha B-40 Electone Organ, a three-keyboard instrument designed for musical creativity. It covers basic safety precautions, such as using proper voltage and avoiding direct sunlight, before detailing the specific features of the upper, lower, and pedal keyboards.
The guide explains how to operate various controls including tone levers, preset tones (Accordion, Piano, etc.), vibrato, reverb, and expression pedals. It also describes the Auto Rhythm Section and Bass/Chord functions, providing instructions on how to utilize these features for performance.
| Pedal Keys | 13 keys (1 octave) |

The B-40 has three different pitch levels indicated by the numbers 16', 8' and 4'. An 8' tone sounds as written, a 16' tone is one octave lower, and a 4' tone is one octave higher.
These are factory preset switches that automatically cancel all other upper keyboard tone lever settings. If two or more buttons are pressed, the one to the right takes effect.
This control governs the relative strength of the upper and lower keyboards. It can be shifted to stress the melody or accompaniment, or used to compensate for volume differences caused by tone lever settings.
