Attaching the Eartips

The OtoRead instrument comes with a box of disposable eartips that
fit a variety of ear canal sizes. The probe tip must have an eartip
attached before inserting it into an ear canal. The eartip kit has 12
different size eartips that are color-coded for easy selection. The
determination of the appropriate eartip size should be made by
persons with proper training and experience.
