Probe care

With use, cerumen can work its way up inside the probe nose cone (probe tip). During the
warm-up period each day and throughout the day, inspect the probe tip to make sure it is clean
and free of cerumen. If any cerumen is detected, refer to the following instructions for cleaning
and maintaining the instrument's probe.

Probe nose cone cleaning

Remove the nose cone portion of the probe:
1. Hold the body of the probe in one hand (e.g. left) near the tip and grasp the nose cone of
the probe in the other hand (e.g. right).
2. Rotate the nose cone portion of the probe counterclockwise until the nose cone is
completely separated from the probe (Figure 1).
3. Place the probe body securely on a table and inspect the nose cone for cerumen. Use a pipe
cleaner to remove any cerumen by inserting the pipe cleaner through the back portion of
the nose cone and pulling it through the front opening. It may be necessary to repeat this
several times to remove all the cerumen.
NOTE:
The probe nose cone can be sterilized via many conventional methods including
autoclaving.
