Because SiS chipsets do not have standard support for USB devices, the U-series phones cannot support the motherboards with SiS chipsets very well. Strong voice may be heard. Equipments which have SiS chipsets are GigaByte GA85G667 Motherboard, Acer 351 Notebook, Toshiba 200 Notebook and Sony SR-27K Notebook, etc. Check www.sis.com for further information.

However, we have provided the latest version Client Software which might solve this problem, if the strong noise still exists even after you already installed it. Please go to our website to download “SIS Patch”. After installation of the SIS patch and plugging the USB phone into the computer, a green arrow will appear in the right-bottom of Windows. The green arrow idicates the installation of SIS Patch is successful.

Download the SiS patch

Notice: The SIS patch does not work with WIN98 and some SiS chipsets.

If strong noise still can be heard after installing SiS patch, we are sorry for no solution for the time being. Please record the SiS chipset model number, motherboard model number and operating system (including language) and report to us. We will solve this in future development.

Some models of the following product brands may have SiS chipset,

3. How to distinguish network quality?

In windows interface, click menu “Start” > “Run” > input “command” > click “Enter” to go to MSDOS.

In MSDOS window:

Input: ping XXXXXX(IP address or DNS)

The window will show:

Reply from XXXXXXXX: bytes=32 time=XXXms TTL=XXX

Request timed out.

Ping statistics for XXXXXXXXXX:

Packets: Sent = 4, Received = 3, Lost = 1 (25% loss)

Approximate round trip times in milli-seconds:

Minimum = 151ms, Maximum = 300ms, Average = 240ms

(i) Delay

The value of “Minimum =” means minimum delay. The value of “Maximum =” means maximum delay. “Average =” means average delay. “ms” is time value(1/1000 sec). The minimum and maximum delay value of packages to the destination is 151ms and 300ms respectively. The average delay is 240ms.

(ii) Jitter

Jitter can be identified by the comparison between Maximum/Minimum Delay and Average Delay. The difference between them is the jitter level.

(iii) Package Loss Percentage

In “Lost = a (b% loss)”, “a” means the quantity of package loss, “b” means the percentage of package loss.

A. For the following:

(i) Public IP dials to regular phone

(ii) Caller and receiver both are public IP

(iii) Caller and receiver both are private IP

You can check the network quality by ping XXXXXXX(IP address of the opposite) to get package loss percentage.

B. For other circumstances

You can check the network quality by ping XXXXXXX(Server DNS) to get package loss percentage.

Reason 2: Problem of Phone hardware

Go to Control Panel, open System Hardware. If “Netphone” and “WZU” device cannot be seen in “USB device”, your phone may have problem. You can connect your phone to another PC to verify.

Reason 3: Abnormal installation of Driver.

Go to Control Panel, open System Hardware. If “Netphone” and “WZU” device can be seen in “USB device” and that device shows yellow ! or ?, please select the driver and reinstall that device. The searching folder of the certain PC is “inf” folder (hided document) in Windows System. Eg. Win2000 document is /Wint/inf/wzu_usb.inf

For example:

Double click the abnormal device, and chose ‘Update driver’

3. Install driver engineer failed: not supported this port

Many users may encounter such prompt” install driver engineer failed: not supported this port “when they install the software under WIN2000 or XP operating system and they fail to install the software.

Method 1: check if you have the administrator authority. Please reinstall it after you get the authority.

Method 2: some system files may be damaged or changed. Please try to repair using SFC demand (sfc /SCANNOW).
Method 3: the installed ACDSEE5.0（especially mini Chinese version）may result in such situation. Please uninstall such version, and try to install other versions.

Method 4: some software’s installation need windows installer support. The solution is: control panel－＞management tools－＞service，find windows installer service，change its startup type to manual startup, then will be OK.. Please remember to stop this service after you successfully install the software. If there are problems, please download the latest windows installer 2.0 version published at Microsoft website.
Method 5: The installation file is single threaded, check the running process. If ikernel.exe is among them, the software can’t be installed now. Please reinstall after stop this process

Method 9: many installation programs are not exe files but msi files, while msi is a new installation script file. Although some installation programs are exe, there are also msi flies in the installation directory; the installation is finished by exe transferring msi. Msi is the script file and the real operated file is "msiexec.exe", which is the cause for all problems. you need install “instmsiw.exe” file. The “instmsiw.exe“compress files need for installing msi., the problems will be solved after run it.

Method 10: reinstall system.
