9. Use F5 to turn ON or OFF the telecoil measurement. The ANSI 96 telecoil measurement
requires the Telewand.
10. Press DATA/GRAPH if you are testing an AGC aid. This will change the function key labels.
Otherwise, skip to step 14.
11. Press F2 to choose a frequency and press F3 to select whether or not you want to run an
input/output (I/O) curve at this frequency. Repeat this for each of the five available frequen-
cies.
12. Use F5 to select the amount of time the first frequency of each I/O curve is presented before
the measurement is made.
13. Use F6 to select the amount of time each subsequent frequency is presented before a mea-
surement is made. This should be at least twice as long as the manufacturer specified attack
time.
14. Use F9 if you would like to identify the ear tested.
15. Return to the main function button selections by pressing DATA/GRAPH.
16. Press F8 to save your settings, if desired.
4.2.3 Running the test sequence
1. Level the sound chamber if necessary. See Section 3.2 for details.
2. Set up the aid for testing. See Section 4.2.1.
3. Close the sound chamber.
4. Press START/STOP when you are ready to begin the test.
5. Wait for several tests to be run. For most aids, the analyzer will pause after performing sev-
eral measurements in order for you to turn down the gain of the aid.
6. If the analyzer pauses, open the sound chamber and adjust the gain control of the aid until
the MEASURED gain matches the TARGET gain to within 1 dB when the sound chamber is
closed.
7. Press START/STOP to resume testing.
8. The analyzer will pause again, if you are performing a telecoil measurement, and instruct you
to put the aid in telecoil mode. Do so. Otherwise, wait for the test sequence to finish.
9. Plug the Telewand into the External Speaker jack on the back of the FP40 and hold the wand
over the aid as you would hold a telephone receiver to your ear. That is, for BTE aids, hold
the wand flat against the body of the aid. For ITE/ITC/CIC aids, hold the wand against the
faceplate of the aid.
10. Press START/STOP to take the telecoil measurements.
11. Put the aid back into microphone mode when the analyzer instructs you to.
12. Unplug the telewand from the External Speaker jack on the back of the FP40.
13. Press START/STOP to complete the test sequence.
