Note: If you want to run contralateral reflex measurements via the PreAmp, you will need a contra phone ID
transducer using the Omnetics plug. The contra phone that connects to the (IMP/OAE) shoulder box uses a
different plug and is not compatible with the PreAmp. Please contact your dealer if you require a PreAmp
compatible contralateral headset (ID transducer).

Handling and selection of ear tips
When using the Titan probe and CIR55 contra phone, appropriate ear tips must be used.
The probe (and CIR55 contra phone) must be fitted with an ear tip of a suitable type and size before testing.
Your choice will depend on the size and shape of the ear canal and ear. Your choice may also depend on
personal preference and the way you perform your test.

When performing a quick impedance screening test you may choose an umbrella shaped ear tip. Umbrella
ear tips seal the ear canal without the probe tip going into the ear canal. Press the ear tip firmly against the
ear canal in such a way that a seal remains during the complete test.

Always use a new ear tip for each patient to avoid cross contamination. The ear tip
is not designed for reuse.
