Using the DVC-1000 (continued)
Switching from a Private Call to a Speakerphone Call
If a VideoPhone call is in progress using a telephone handset, Speakerphone
Mode can be enabled:
Press the Speakerphone button on the DVC-1000 remote control.
When the dialog appears on the video display telling you to hang up
the phone, go ahead and hang up the phone.
Speakerphone Mode is now active.
When in Speakerphone Mode with the built-in microphone, you should face the
DVC-1000 VideoPhone unit when you speak so the microphone will pick up all
your words. Speak louder as you move further from the microphone. The
recommended distance from the microphone in Speakerphone Mode is 6 to 8
feet. The volume of the built-in microphone can be adjusted from the
Settings>Mic Vol Screen (see page 38.)
Using an External Microphone for Speakerphone Calls
To improve the audio in a group videoconference, an external microphone can
be plugged into the external microphone connector on the back of the
DVC-1000. When an external microphone is used, the built-in microphone on
the front of the DVC-1000 is disabled.
