To have a meeting in a large conference room or with a large number of persons, some ProjectPhone systems can be 
connected as slave units to this system. The number of connectable systems varies depending on the installation 
environment.

• In an interlocked connection of the ProjectPhone systems, allow a distance of at least 2 meters between them.
• Set the “Room Size” to “Small” for an interlocked connection.
• If echo or howling is produced, install the ProjectPhone systems at larger distances or decrease their volumes.
• To avoid the echo or houling, set the volume level setting of each Project Phone system to the same level.

Using stereo mini-plug cables, connect the AUDIO OUT terminal of each ProjectPhone system to the AUDIO IN
