When disconnecting the plug, do not twist it. Instead, hold the sleeve of the plug and release it by pulling it straight out of
the socket.
The probe will not be released if you pull anywhere else than on the sleeve of the plug.

Preparing the test environment
Physical environment
•
Make sure that the test environment is as quiet as possible. The quieter the room is, the more accurate and quick
your testing will be.
•
Check that testing is not being done under an air conditioner or in front of a fan or ventilator.
•
Check that there are no mobile phones in the vicinity, people talking etc.
Hygienic precautions
•
Be sure to follow any established infection control procedures for the setting in which you are working.
•
Clean probe body, probe cable and probe plug before each patient or if surface is visibly contaminated.
•
Use a sterile alcohol wipe to clean the surfaces and wait until the probe body, probe cable and probe plug are com-
pletely dry.
Note
•
A sterile alcohol wipe typically contains isopropyl alcohol 70%. It is important to have the disinfectant in
contact with the surface for the time period specified by the disinfectant manufacturer to ensure its effectiveness.
•
Always use new eartips.

Preparing the patient
General preparations of the patient
1. Position the patient so that you can easily access the ear to be tested.
2. Grasp the pinna and gently pull back and slightly away from the patient's head.
3. Look into the ear canal.
4. Inspect the ear canal to make sure it is clear of cerumen or debris as this may affect the res-
ult of the test.
