Ear tip to be placed on probe tip of contra phone
Probe tip screwed onto contra phone
Connector to CONTRA socket on Otowave 302+
The contralateral transducer is used when it is required to provide a reflex stimulus to the opposite ear to that being
tested with the main probe assembly. For use it should be connected to the CONTRA socket on the base unit and fitted
with a new ear tip.
The contralateral probe tip may be replaced if necessary (e.g. if damaged). To remove the contralateral probe tip,
carefully unscrew it from the body of the transducer. Carefully fit the replacement part and make sure that it is screwed
home firmly but do not over-tighten. Do not use any tools to tighten the contralateral probe tip.
2.9. CHOOSING THE CORRECT EAR TIP SIZE
Amplivox YouTube video is available for assistance on how to choose the right ear tip.
The probe tip must be fitted with a new ear tip before it is presented to a patient’s ear canal. If a contralateral reflex
stimulus is to be applied, fit a new ear tip to the contralateral transducer before presenting it to the patient’s opposite
ear canal.
