Normal box format
It is possible to have the normal box, as described by ASHA, appear on the tympanogram
screen and printout. The boundaries for this normal box are -150 daPa to +100 daPa and 0.2 cm
to 1.4 cm
3 .
NOTE: A compliance value of 1.5 cm 3 or greater will automatically turn off the ASHA
normal box.
The normal box is the default setting. To deselect this normal box:
1. Move the square cursor with either the < or > Hz button so that it is placed in front of the
words Normal Box Off.
2. While the cursor is in this position, select the M+ pushbutton to save this feature as the
new default setting.
Note that the word SAVED appears in the lower right-hand margin. This message assures
you that the normal box will not appear on the tymp screen or printout.
Audiogram range
All eleven frequencies are available during audiometry or the range can be abbreviated to eight
frequencies. The default setting is Aud Range Normal. To select the abbreviated frequency
range:
1. Position the square cursor in front of the feature Aud Range Narrow.
2. Press the M+ button to save this narrow range for audiometric testing.
Note that the word SAVED will appear in the lower right-hand margin and the asterisk
now appears in front of the narrow range selection. The normal range of frequencies
includes 125 Hz through 8000 Hz. The narrow range of frequencies includes 500 Hz
through 6000 Hz. Please note that in the Aud mode, if the narrow range is selected, the <
and > Hz buttons will allow you to scroll through this abbreviated frequency range only.
Both the screen and printout will still be labelled with the full range of frequencies i.e.,
125 Hz through 8000 Hz.
Exiting the program mode
1. Press the PROG button to exit the program mode and return to the test mode that was
operational prior to entering the program mode.
