Your LVA-i is supplied with a new model of handset. This handset is a crucial component of
the system that enables the LVA-i full control over the voice capturing and its quality.
The new handset model has an integrated sound card within. This enables the LVA-i to
ensure that no matter what type of hardware & sound card model you are running LVA-i on,
it will always use the sound device within the handset to ensure full compatibility and sound
quality of the voice captured.
The handset components
The handset is delivered disassembled into 3 parts:
1. The handset body

Sound Test
In order to ensure proper voice input, it is recommended to perform a sound test before
each test session. This test should be taken lightly, and should be performed according the
on-screen instructions. While the playback volume adjustment is designed for the applicant's
convenience, the input volume test is made to ensure optimal volume of voice is processed
by the system.
You can access the sound test by clicking the “cancel” button in the sign-on
screen, or from the test Welcome screen. Click on the Sound Test icon.
The system will ask you to perform a sound test for both playback (speakers)
and input (microphone).
To test the volume of the speaker's output, click and hold the button with the speaker icon.
A tune will be played. You can adjust the volume by moving the slide bar beneath the
speaker icon left or right. If the sound is OK –proceed to test the microphone (Figure 19).
To perform the microphone test, hold down the microphone button and count up to 10
while speaking into the microphone in your NORMAL speaking voice. While doing so –a
message will notify you if the sound is adequate, too high or too low. If necessary, use the
slide bar beneath the microphone icon to adjust the input level until it is OK (Figure 19).
Every time you release or press again on the Microphone button, it will reset the message
and will conduct a new volume test.
