To exit from the Stenger or ABLB test modes press TEST MENU until THL
is displayed (or ULL if this has been selected) and the green indicator
above the key goes out.
3.5 Threshold Retention Function
This function stores the last presented combination of ear, tone and
frequency for every frequency tested in the audiometer’s memory (air
conduction and bone conduction). Once a threshold has been determined
press the “selected” ear key once again and the level will be stored and
displayed in a similar way to that shown in the illustration below.
The operator can then review the results at the end of the test and record
them on an audiogram card, print them with the optional printer (see
Section 2.5), store them in the internal memory (see Section 3.6) or
transfer the results to a NOAH database on a computer (see Section 2.6).
To review the retained thresholds, select the frequency using the
FREQUENCY keys. The values for the left and right ears are shown
on the lower line of the display as shown below.
SIGNAL FREQUENCY Hz MASKING
To set and review bone conduction thresholds use the BONE key. To
store and review ULL, switch to this mode (see Section 3.4.2)
To clear the Threshold Retention memory, use the Clear test menu option
described in Section 3.4.2.
3.6 Saving audiograms in internal memory
The user may store up to 12 audiograms, referenced by number, in the
internal memory of the audiometer. To save the current set of audiogram
thresholds (the “retained” values described in Section 3.5) press and hold
the MENU key, press FREQUENCY repeatedly until “Save Audiogram
to 1” appears on screen. Use the SIGNAL keys to select a location
numbered 1-12, and then press the YES key. Release the MENU key
once confirmation appears on the display.
