Preparing for Testing
Use the accessories provided with your Avant Audiometer. Typical acceptable transducers
are shown on the “Transducer & Accessories” page in the Installation manual. Operator
headsets for use with the Avant Audiometer should have 32 ohms impedance and the
speaker power should be at least 50 watts. Air conduction transducers for use with this
device should have an impedance of 10 ohms. The speaker voltage should match the local
mains voltage where the device is used.
The Operator Headset with microphone is used by the device operator to communicate
with the patient. The patient talks to the operator using the Talk-Back microphone.
Placing the Earphones on the Patient
IMPORTANT: The foam tips used for the insert earphones are for SINGLE PATIENT USE ONLY.
Do not attempt to wash and re-use them.
1. Place a new set of foam tips on the earphone tubes as shown.
These tips are designed for single patient use and should not
be washed and reused.
• NOTE: When removing foam tips after use, be sure the clear
plastic tubing nipple remains attached to the long
earphone tube.
2.
Carefully compress the tip between
your fingers to allow it to fit into the
patient’s ear canal as shown. Do not
roll the tip between your fingers.
3. Pull up and back on the patient’s
pinna to straighten the ear canal.
4. Place the compressed foam tip deep
within the ear canal.
5. When properly placed, the outer
surface of the insert tip will be flush
with the opening of the ear canal as
shown.
