To adjust the binaurals on your Riester stethoscope, please follow the instructions below:
1. For models duplex®, duplex® baby, duplex® neonatal, tristar®, anestophon®, ri-rap®:
- Ensure that the binaurals are adjusted to the anatomically correct angle. They should slightly sit in front.
- The angle can be adjusted by turning the binaurals individually.
- The ear-tips should rest completely at the same angle as the external auditory canal for optimal sealing and to block out external noises.
- 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.
2. For models cardiophon 2.0, duplex® 2.0, duplex® 2.0 baby, duplex® 2.0 neonatal:
- The binaurals are anatomically correctly pre-adjusted during production.
- The contact pressure of the binaurals may be adjusted individually if needed.
- The ear olives are pivotable and have extra-soft material for perfect sealing of the auditory canals and to prevent disturbing noise during movement.
Please note that the ear olives should not enter too deeply into the auditory canal.
For visual reference, you can refer to the figures provided in the manual (Fig. A, B, and C).
If you continue to experience difficulties adjusting the binaurals, it is recommended to contact the Riester customer support or an authorized Riester specialist dealer for further assistance.
