Using the Mwave DSP Features

The computer provides the Media Processor (Mwave DSP) feature, which is based on the digital signal processor (DSP). It gives you high performance for audio and telephony functions.

Note: In some countries, the Mwave telephony functions are only available with the DAA/Telephony Kit option installed.

This illustration shows the connections between the computer and external cables or devices:

The Mwave DSP feature supports the following functions for each operating system:

Using the Audio Function

Use the Mwave audio functions according to your operating system.

Using the Audio Function for OS/2

When Using a CD-ROM or a Music CD When you use a CD-ROM or a music CD with your computer, make sure of the following: Open the Mwave for OS/2 folder in the OS/2 desktop. Double-click on Auxiliary Control. Make sure that Line/CD is selected as the auxiliary source. Note: Select Mic when you want to use the computer as a microphone-speaker.

Using the Audio Function for Windows

To control the audio input or output, do the following:

1. Select Mwave ThinkPad from Windows.

2. Select Audio Control. The following window appears:
   
   

This window allows you to maintain control over volume, balance, tone, and effects for all audio components and input sources. For more information, see Mwave Help in the Mwave ThinkPad window.

Using the Audio Function for DOS

To enable Sound Blaster support for DOS games:

1. Type FASTCFG at the command prompt; then press Enter.

   The FASTCFG utility opens.

2. Select Games; then select OK.

If you do not have enough memory for your games, you should make a boot diskette before starting the DOS games. To make a boot diskette, do the following:

1. Start DOS and insert a blank diskette into the diskette drive.

2. Type MAKEBOOT at the DOS prompt; then press Enter.

   A boot diskette is created. Before starting your games, restart the computer with this boot diskette inserted in the diskette drive.

Some sample files, such as the CONFIG.SYS file, are created on the boot diskette. You might need to modify these files by referring to the manuals that came with your games. Default Values for DOS Games Audio

Most games automatically determine the I/O address, interrupt level (IRQ), and DMA channel settings for the audio for DOS games. If the game asks for this information, specify the default settings for Sound Blaster as follows:

   I/O Address

220

   IRQ

5

   DMA Channel

1

If you need to change these settings, use the ThinkPad Features program.

ThinkPad Features program: > "Using the ThinkPad Features Program".

Using the Telephony Function

Caution:
Your computer can use only a public-switched telephone network (PSTN). Do not use a PBX (private branch exchange) or other digital telephone extension lines. Use of phone lines other than PSTN can damage your modem. If you are not sure which kind of phone line you are using, contact your telephone company. Many hotels or office buildings use digital telephone extension lines, so check before connecting the telephone cable in such places.

If the modem is damaged by your incorrect use, an additional charge is required for repair.

To use the telephony functions, you need to connect a telephone line to your computer.

DANGER!
To avoid shock hazard, do not connect the cable to or disconnect the cable from the telephone outlet on the wall during electrical storms.

When your computer has a modem/fax port with a square receptacle, first connect the ferrite-core end (connector ) of the telephone cable to the modem/fax port; then connect the other end () to the telephone outlet on the wall. (Ref #39.)

Note: If you use both the computer and a telephone with one telephone cable, use the telephone cable supplied with your computer. If you use the DAA/Telephony Kit (available as an option), see reference #95.

Important

Make sure you use the correct telephone line so your modem operates correctly. When you are: At home: Use an analog line, a standard household telephone. In your office: Use a line connected to a fax machine or another modem. In a hotel: Request a room with a data or normal telephone line. Your RJ11 jack must be wired for an analog line. If you are not sure what type of line you are connecting, check with the telephone company.

Using the Modem with OS/2

1. Open the Mwave ThinkPad folder.

2. Double-click on the Mwave Modem icon.

   The Mwave modem starts automatically.

3. Start your communication program.

Using the Modem with DOS

1. Type FASTCFG at the DOS prompt; then press Enter.

   The FASTCFG utility opens.

2. Select Advanced Modem; then select OK.

3. Start your communication program.

Using the Modem with Windows

Using Country Selection

The Country Selection window allows you to change the country name currently supported by the Mwave telephony features. When you travel to other countries and use the Mwave telephony function, you need to select the country name from the list of countries in this window.
