NOTE: See the documentation that came with the TAPI-compliant card for more information on using TAPI devices and
to verify that the card works with your computer.
Your computer supports TAPI-compliant modem cards using the standard TAPI connector (the green connector labeled
MODEM or TELEPHONY). If your modem supports voice features, you can connect your modem to the TAPI connector and
then use your audio speakers and microphone as an answering machine or speakerphone. The microphone carries your voice
into the computer and then through the TAPI system board connector to your modem card. The caller's voice enters through
the modem card to the TAPI system board connector and then out to the speakers. You can also use this configuration to
record and play audio files over the telephone by using third-party software.
CAUTION: Before you begin any of the procedures in this section, follow the steps in " CAUTION: Safety
Instructions ."
CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before
opening the cover.
