Configuring the Modem for Your Country
Different countries have different requirements for how modems must function. Therefore, before you
use the modem, you must configure it to match the defaults of the country in which you are using it.
You can configure the MT9234MU either manually using AT commands or with the Global Wizard.
Both methods are described below.
Using the Global Wizard Utility to Configure Country Code
The Global Wizard configuration utility is recommended for computers running Windows Vista,
Windows Server 2008, XP, and 2003. The Global Wizard can configure your modem for a
specific country with just a few mouse clicks.
1. Insert the MT9234MU Installation CD into the CD-ROM drive. The Autorun dialog box
appears.
2. Click Initial Setup and Country Selection. The Global Wizard dialog box appears. Click Next.
3. View the Global Wizard as it searches for your modem and identifies it. Click Next.
4. Select the country in which the modem will be used, and then click Next.
5. Review your choice of country. If it is correct, click Next to configure the modem.
6. When Global Wizard announces that the parameters have been set, click Finish to exit.
Using AT Commands to Configure Country Code
If you are comfortable using AT commands, you can configure your modem using AT commands.
You must enter these commands in your communication program’s terminal window.
To configure the modem for a specific country, execute the following AT commands:
1. Type AT%T19,0,nn (where nn represents the country code). Press Enter.
2. The modem will respond “OK.”
3. Type AT&F&W (this saves changes). Press Enter.
4. The modem will respond “OK.”
5. Type ATI9 (this verifies that country code has been chosen). Press Enter.
6. The modem will display the country code in decimal format followed by an “OK.”
7. Check to be sure the code for your country is displayed.
If not, repeat procedure to correct.
Here are two examples of country, command, and result codes.
Example Country/Region AT Command Country Code
(Hexidecimal) (Decimal)
Euro/NAM* AT%T19,0,34 (default) 52
The complete list of country/region codes can be found on the Multi-Tech Web site at

Then click on global modems. The Global Modem Country Approvals page displays. On this page you can view
approvals, configuration strings and responses by country and product.
