Removes the following text:
Volume Boost:
No Volume Boost
Volume Boost 1
Volume Boost 2
Volume Boost 3"
Uses the following text instead:
Volume Boost:
No Volume Boost
+4dB
Removes the following text:
Set the Boost level to increase the volume output of the speaker. Using Volume Boost may
introduce audio clips or lessen the effectiveness of the echo canceler. Boost is only
recommended for use with volumes set to level 9.
Normal operation of the product can be met with volume levels 0 through 9. 0 being mute and 9
being the loudest volume that in a normal arm's length and average background noise, will
enable full duplex operation and give the best quality of sound output.
The volume boost options increase the output of the speaker by:
3db for Boost level 1
6db for Boost level 2
9db for Boost level 3
If the user would like a higher output from the speaker, the Boost settings are available.
However, operation in Boost Mode may overdrive or clip the audio if, for example, the phone that
is connected has a high microphone gain or if the person has a loud voice talking too close to
the microphone.
The acoustic echo canceller also has a harder time maintaining full duplex operation when in the
Boost Mode. The product may drop from full duplex operation into half/duplex mode while in
Boost Mode.
Contact CyberData support for additional information if needed.
Uses the following text instead:
Set the Boost level to increase the volume output of the speaker. Using Volume Boost may
introduce audio clipping and/or distortion. Boost is only recommended for use with volumes set
to level 9.
