Problem

Possible Cause

Solution

If audio is output from the

display properly when the

audio test is performed, it

indicates that the problem

exists at the remote site.

The microphone at the remote site

has been muted or the chair site

has muted the microphone of the

remote site.
No audio transducer, such as a

microphone, is connected to the

audio interface that is set as the

audio source. In this case, set the

audio source again or connect a

sound pickup device to the

corresponding interface.
The relevant sound pickup device

is powered off. In this case, power

on the device.
The audio cable is not connected

securely. In this case, connect the

audio cable properly.

After the local site

joins a conference,

only the sound from

the local site can be

output from the

display and the

other sites cannot be

heard.

A loopback test is being

performed at the local site.

Stop all local and remote loopback

tests.

Conference Initiation

Table 13-10 describes the troubleshooting methods for the problems that arise during

conference control.
