Automated Test Sequences 105
4. Use [F3] to select the full-on gain (FOG) amplitude used in the test
sequence. We recommend setting this to AUTO, which will automatically
use the appropriate amplitude. This step does not apply for ANSI 03.
5. Use [F5] to select whether or not to perform a telecoil measurement.
6. Press [MENU] to enter the local menu and make any desired selections. See
Section 5.1.10.
Use [F7] to return all ANSI settings to their power-on default conditions.
Use [F8] to display all selected ANSI settings.
5.1.5 Running an ANSI 96 or an ANSI 03 Test
After leveling the sound chamber as described in Section 5.1.2, setting up the
aid as described in Section 5.1.3, and setting up the analyzer as described in
Section 5.1.4, follow these instructions:
1. Press [START] to begin the test. Usually the 8000 test system will pause during
the measurement process in order to let you adjust the gain of the hearing
aid to the reference test position.
a. Lift the sound chamber lid and adjust the gain control of the aid until the
RTG MEASURED gain matches RTG TARGET.
b. Close the sound chamber lid when finished.
c. Look at the display again. The MEASURED gain should be within 1 dB of
the TARGET gain for ANSI 96, or 1.5 dB for ANSI 03.
2. Push [START] to continue the test.
3A. If you chose to perform a telecoil measurement, do the following steps when
the analyzer pauses. If you are running an ANSI 03 test of an AGC aid and
are not performing a telecoil measurement, skip to step 3B. Otherwise, just
wait for the test sequence to complete.
a. Open the lid of the sound chamber.
b. Switch the aid to telecoil mode.
c. Plug the telewand into the side of the sound chamber, just above the
cable that connects the sound chamber to the Frye box.
d. Hold the telewand over the aid as if it were the ear piece on a phone.
That is, hold the telewand parallel to the body of a BTE or against the
faceplate of an ITE. It’s also usually best to position the hearing aid vertically
to get the best telecoil response. See Figure 5.1.5.
e. Press [START] to measure the telecoil response. The analyzer will pause
after the telecoil measurements are complete.
f. Return the aid to the normal microphone mode, set the AGC controls
to max (ANSI 03 and AGC aids only), reposition the hearing aid in the
sound chamber, close the lid, and press [START] to complete the test
sequence.
