When doing a 226 Hz probe tone test, use the White Flat tips, 26100. The 226 Hz probe
tone test auto-starts the pressure sequence and placing the probe in the ear canal when
the pressurization begins can result in unwanted deflections in the tympanogram. The
White Flat ear tips allow the user to place the probe and hold the Probe Tip at the
entrance to the patient's ear canal while the tympanogram and reflex testing are
performed.
The probe is occluded. Remove the probe and inspect for cause of occlusion.
Blinking - The instrument is ready to begin a Tymp. Steady green - Test successfully
started and in progress.
A pressure leak has been detected.
WARNING A Welch Allyn provided Probe Tip must be used. Using the probe
without the Probe Tip could result in injury to the subject.
