•
Avoid using the standard mode when the far-end party is in a "noisy" environment—
typical with cell phone callers.
•
Avoid using the standard mode when the call is a conference call with multiple parties
because the likelihood of one or more of the parties having background noise is high.
•
Standard speakerphone operation is half-duplex or "switched" and switches to the
"loudest" party. Half-duplex means that if both parties talk at the same time, only one
party (the loudest party) will be heard.
•
The far-end talk "level" is based on your speaker volume setting (1 to 8). The louder
you set the volume, the more difficult it becomes to interrupt the far-end party.
•
As a general rule, the far-end talk level is "louder" than the near-end talk level giving
the far-end party priority when talking.
•
The farther away you are from the phone, the lower the talk level.
•
The speakerphone adjusts to ambient "noise" level in the room, which is why you need
to keep the phone away from noise generators (such as PC fans) and talk within four
feet of your speakerphone.
12.23 Keep in mind the following guidelines when using the enhanced mode:
•
Follow the same guidelines as those listed for the "standard" speakerphone, and, in
addition to the guidelines for an enhanced speakerphone.
•
Inform the far-end party about the burst of white noise before you enter the enhanced
mode.
•
Use volume levels 1-3 for full-duplex operation.
•
Avoid using the enhanced mode on calls with significant delay.
•
Avoid using the enhanced mode on volume levels 4 through 8 since the speakerphone
transitions back to half-duplex operation.
•
The enhanced speakerphone provides full-duplex operation at lower volume settings (1
through 3) but transitions to half-duplex operation at higher volume settings (4 through
8). Full-duplex means both parties can talk at the same time and hear each other.
•
The enhanced mode does not perform acoustic echo cancellation, so the far-end parties
always hear their own acoustic echo.
•
The far-end party will hear all near-end background noises.
•
The far-end party must be on a handset for full-duplex operation.
