Ear Sensor Use
Ear Sensor Insertion
1) Roll the disposable yellow E.A.R.® foam ear plug, containing a black protruding tube,
back and forth with the fingers until it forms a small crease-free cylinder. See Figures 2
and 3.
Figure 2
Figure 3
2) Using only light pressure to keep the E.A.R.® plug rolled tight, gently slide it over the
sensor of the earmold assembly. The black tube should slide into the earmold leaving
only the yellow foam plug visible. The sensor should fill the black tube of the E.A.R.®
plug with the tip lying flush with, or just inside of, the outer end of the tube.
3) With the E.A.R.® plug still rolled tight, hold on to the blue earmold and quickly insert
the rolled up plug into the ear canal and hold it in place until it expands. The yellow
portion of the earplug should be completely contained within the ear canal without any
danger of hurting the inner ear. Fitting is easier if the outer ear is pulled outward and
upwards during insertion as shown in Figure 3. Once the plug has expanded, pushing or
twisting will not improve its fit therefore, if the initial fit is inadequate, remove the plug
and repeat the process.
