These models were designed with simplicity in mind. They are lightweight and slender for easy handling. Therefore, using the models in also very simple. Listed below are the steps for operating the models.

1. Remove desired model, connecting piece, and electro-larynx from casing.
2. Adjust the volume and frequency dials of the electro-larynx until a loud consistent buzz is achieved. The models were tested successfully at the frequency of approximately 97Hz if such precision is required. However, they will work with most frequencies.
3. Slowly but firmly press the electro-larynx into one side of the connecting piece. This will be a tight fit and insertion might require a slight twisting motion.
4. Read both ends of the model to determine which is the glottis and which is the lips Labels have been carved into each end for ease.
5. Holding the electro-larynx and connecting piece combination in your non-dominant hand, slowly insert the glottis end of the model into the free side of the connecting piece. This will not be as tight of a fit but may still require some force.
6. Holding the model and connecting piece tightly in one hand, use the other to turn on the electro-larynx. This is done by pushing and holding the large round button on the device’s side.
7. Listen to the sound produced by the model. If an audio recording is required, set up those devices prior to beginning model set up.
