AmpliVox Otowave 302+ - Understanding Tympanometry Results

USING THE OTOWAVE 302+
33 OTOWAVE 302+ INSTRUCTION FOR USE
As soon as the probe is removed from the ear, the test result
for the ear measured will be displayed on the screen.
Please note: If BOTH EARS had been selected to be tested,
the test on the other ear will be performed after the test review
