Automated Test Sequences

To change the ANSI 03 settings:

1. From the ANSI 03 screen, press F1 to enter the General Setup Menu.

2. Use the AMPLITUDE and FREQUENCY knobs to select MENU TYPE.

3. Press START/STOP to choose PARTIAL. The menu will now only display the selections appli-

cable to ANSI 03.

4. Use the AMPLITUDE and FREQUENCY knobs in conjunction with the START/STOP button

to choose the settings for NOISE REDUC, SETTL. TIME, and AVG FREQS under PURETONE
SETTINGS. These settings are explained in Section 2.4.1.

5. Use the AMPLITUDE and FREQUENCY knobs in conjunction with the START/STOP button to

select whether or not you will use the REFERENCE MIC for testing. We generally recommend
selecting OFF. See Section 3.4.9.

6. Use the AMPLITUDE and FREQUENCY knobs in conjunction with the START/STOP button to

select the type of battery pill used in the measurement. This is used in testing battery current
drain.

7. Press F1 to return to the ANSI 03 screen.

8. Press F2 to choose the type of aid you are testing. The selections are AGC, ADAPTIVE AGC,

and LINEAR 50.

• Choose LINEAR 50 for linear aids.
• Choose AGC for most AGC aids.

• Choose ADAPTIVE AGC if the aid has adaptive release times. This is also a suitable selec-

tion for digital aids that require extra time to adjust to input signals.

9. Use F5 to turn ON or OFF the telecoil measurement. The ANSI 03 telecoil measurement

requires the Telewand.

10. Press DATA/GRAPH. If you are testing a linear hearing aid, skip to step 15.

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 F8 to SET AGC ON or OFF. SET AGC ON will cause the test sequence to pause in order

to allow you to adjust the AGC controls of the aid before running the input/output curves as
required by ANSI 03. If it is not possible for you to adjust these controls, SET AGC to OFF,
but be advised that test results may vary from manufacturing specifications.

15. Use F9 if you would like to identify the ear tested.

16. Return to the main function button selections by pressing DATA/GRAPH.

17. Press F8 to save your settings, if desired.
