If no response is detected in one or both ears, the line for that ear will not
reach the 100% green area after 180 seconds, the result will be “REFER”.
NOTE: For Binaural Testing, a “PASS” result can only be obtained when the
100% pass criteria are reached by both ears. If either of the ears fails to
reach the 100% pass criteria after three minutes, even if the other ear had
reached the 100% pass criteria, the screening result will be shown and
recorded in the database as “REFER” for proper follow-up actions (Figure
24).
