Step 1 Pick a good spot

Prolonging the lifespan

Avoid storing or operating VT640P in abnormal conditions. High temperatures or excessive humidity could cause the unit to malfunction and shorten its useful lifespan.

Stability

Place your VT640P on top of a counter, desk, or table with the CCD camera opening in front.

Lighting condition

Make sure the lighting is sufficient and does not shine directly into camera lenses.

View of camera

Avoid using VT640P in a room with brightly painted walls or flamboyant wallpaper. Soft and evenly painted background provides the best results.

Installing the unit

Step 2 Hook up the handset

Connect the handset and the VT640P main unit with handset cable.

Connect the handset cable.

Remote Update Completed.

Please Reboot.

The updated software will be created to suit the ongoing development of the Internet environment. Users who continue to use VT640P under the same connection do not need to renew the software. If you do not know whether you should update the software under certain circumstances, visit our website at http://www.visiontech.se for information you need.

Note:

If the update fails, the screen as shown to the right will be displayed. Please reboot the VT640P manually.

The Bandwidth Setup in VT640P divides the bandwidth into 5 levels: (in Kbps)

1. 128

2. 256

3. 384

4. 512

5. 638

Note that the bandwidth affects the quality of video transmission; a low bandwidth setting that leaves too much bandwidth unused is a waste of connection resources, and a high bandwidth setting that exceeds the bandwidth that is available will jam the transmission and the video quality will be far lower than expected.

To choose the bandwidth that makes the most effective use of your connection, read the following carefully.

For home users:

Set the bandwidth you wish to be used by the VT640P. It should not be more than the bandwidth of your type of connection.

Note for ADSL users:

The upload and download rates of VT640P are the same. ADSL is a type of connection whose download rate is not the same as the upload rate. ADSL users are advised to set the lower rate of the two as the bandwidth to be used by VT640P.

For business users:

It is best to reserve a certain amount of bandwidth for videoconferencing on a LAN connection for the VT640P users to set its bandwidth accordingly.

and : Item selection

If you use PPPoE to connect to Internet, please do not set the bandwidth to higher than 384K.

Note : You can assign your own IP, Subnet Mask and Gateway within your private segment. If the segment is

Step 1 Turn on the power of the unit. The LCD screen shows the local view, the

image of the caller.

Step 2 Pick up the handset. Enter the desired IP address/number * (See note). Use

the " " key to input the dots between the numbers. When a key is pressed, the image on the LCD screen disappears and the numbers you input are displayed.

Step 3 The other party answers the phone, and the video connection is established.

You will be able to see the person you are talking to.

Step 4 To end the connection, simply hang up the handset.

Step 5 If there is difficulty in making connection, please make sure that VT640P

has been properly installed. Please also check if the network settings are correctly configured.

Power Saving Mode

The VT640P incorporates a power saving circuit to protect its internal components and extend its service life.

If the VT640P is inactive for 5 minutes, the LCD screen automatically shuts down and goes blank. The power indicator blinks.

The image returns to the screen when the handset is picked up or any key is pressed.

*Note: To dial numbers, VT640P must work in conjunction with additional accessories, such as the H.323 Gatekeeper.

Use the self-view image and focus knob to get the best shot of yourself.

Adjust the hue and brightness of the screen for best image.

Before making a video call

Avoid having a lot of movement in the background and try not to move around excessively. Too much movement tends to slow down the frame rate of the video image, resulting in a jerky picture.

Note : IP, Subnet Mask and Gateway are assigned by your DHCP server.

The DHCP Server must be able to support dynamic-fixed IP allocation.

This firewall must be able to enable packets I/O for TCP port 1720-1729 and 7000-7009 and UDP port 8050-8054 (for VT640P exclusively).

It must also be able to provide the NAT service, and the following static routes should be set: TCP port 1720-1729 and 7000-7009 and UDP port 8050-8054. Or you can put VT640P into DMZ if your router supports this function.
