Configure the Modem for Your Country
Different countries have different requirements for how modems must
function. Therefore, before you use your modem, you must configure it
to match the defaults of the country in which you are using it. For
Windows Vista, XP, 2003, and 2000, you can configure the MT9234MU
either manually using AT commands or with the Global Wizard. For
Linux, AT commands must be used. Both methods are described below.
Using Global Wizard to Configure Your Modem
The Global Wizard configuration utility is recommended for computers
running Windows Vista, XP, 2003, and 2000.
1. Insert the MultiMobileUSB system CD into the CD-ROM drive.
The Autorun dialog box appears.
2. Click Initial Setup and Country Selection.
3. Choose either:
•Run Global Wizard from CD. This will not load the wizard
onto your hard drive, or
•Install Global Wizard on the HD. This will install the wizard
onto your hard drive for future use.
4. The Global Wizard dialog box appears. Click Next.
5. The Wizard searches for your modem and identifies it. Click Next.
6. Select the country in which the modem will be used. Click Next.
7. Review your choice of country. If it is correct, click Next to
configure the modem.
8. When Global Wizard announces that the parameters have been
set, click Finish to exit.
