To adjust the binaurals on the Riester 133251gruen Duplex Neonatal Stethoscope, follow these steps:
1. Ensure that the binaurals are adjusted to the anatomically correct angle. The binaurals should be worn so that they slightly sit in front.
2. The angle of the binaurals can be adjusted by turning them individually. The ear-tips should rest completely at the same angle as the external auditory canal for optimal comfort and to block out external noises.
3. If the contact pressure of the binaurals is too weak, take both binaurals and press them together. If the contact pressure is too strong, take both binaurals and expand them.
4. The soft Riester ear-tips are designed to provide a good fit and seal in the auditory canal, reducing external noise and ensuring optimal sound transmission.
Please refer to the instruction manual for visual illustrations (Fig. A, B, and C) on how to adjust the binaurals correctly for your specific model of the Riester stethoscope.
