Note
If your video conferencing room is large, you can add an extra CPE80 expansion
microphone to the MIC port on the VCP40 phone to expand the audio range of the
conference phone. VCP40 phone has two MIC ports. This allows you to connect a CPE80
expansion microphone to one of the ports, depending to the location of the speaker.
CPE80 is a directional microphone. Its coverage range is a 60 degree. Always ensure
that the speaker faces the expansion microphone.
Dispose of waste batteries properly.
Remove the batteries if they are not in use for a long period of time.
