measurement, use the ear coupler cable. The main advantage of the ear coupler cable is that you can test both ears at the
same time or in sequence after starting the test.
1. Place AccuScreen face down.
The sleeve on the plug of the ear coupler cable and the colouring around the ear coupler socket are blue.
2. Align the ridges on the plug with the notches in the blue-bordered socket on the top end of AccuScreen.
3. Gently insert the plug into the probe socket. The plug does not require force to be inserted properly.
Disconnecting the cable
Caution
•
Do not pull the plug by the cable when you disconnect the ear coupler cable. Instead, pull the sleeve of the
grey connector.
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 cable 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.
•
Clean ABR electrode cable and electrode cable 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.
