Before installing and using theVC400 video conferencing system, you need to be

familiar with the following system components:

VC400 codec compresses outgoing video and audio data, transmits this information to

the far end, and decompresses incoming data. It supports 16:9 and 4:3 aspect ratios. It

can be compatible with different audio output devices, and can adapt to the display

devices automatically.

You do not need to change the VC400 codec once it has been installed properly in your

conference phone. VCP40 phone has two MIC ports. This allows you to connect a CPE80

expansion microphone to one of the ports, depending on 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.

Note

Dispose of waste batteries properly.

Remove the batteries if they are not in use for a long period of time.

Caution! In order to avoid corrupting the system, you should always power off the system
using the power button on the codec. After turning the power off in this way, wait at least
15 seconds before you unplug the system from its power source. This helps ensure that
the system powers off correctly.

The VC400 video conferencing system supports SIP and H.323 call types. You can

configure which type to be used when the system is making calls. When the Auto call

type is used, the system preferentially uses the H.323 protocol to place calls. If there is

no available H.323 account on the system, the system will switch to the SIP protocol. You

can also specify the desired protocol for the system to place calls via the remote control

or web user interface.

Note

To configure the call type via the remote control:

1. Press (Menu soft key) to enter main menu.

2. Press or to select the Call Features menu.

Before configuring call type, ensure the remote system supports the call type too.
