(EAL) Toy Test
This section describes the options available for running the McCormick Toy
Test in Wideband noise. The procedure is the same for MTT in Quiet
except that the noise level is set to 0dB and is not displayed. MTT in
Babble noise is the same except babble noise is substituted for Wideband
noise during playback.
Setup test
This screen is displayed when the test is selected. In Setup test you can
perform the following operations:
Adjust the noise level with the [noise up] and [noise down] keys.
(The noise level can be adjusted in 5 dB steps from 75 dB to 30 dB and then to 0
dB if you wish to temporarily remove the background noise)
Adjust the speech level with the [speech up] and [speech down] keys.
Enter the [Toytest Options] menu using the [Menu] key (see page 7).
Run the Toytest using the [Select] key.
Pressing the [Select] key will cause the handset to begin playing the 14
words of the MTT. The display will change slightly in play mode as shown
below.
