Important: If you must update the modem driver
If Step 2 of the software installation procedure revealed that the PC’s unimodem.vxd file is not at
least version 4.10.31, you must update this modem driver file before installing the TAPI Phone
software and before the TAPI Phone can operate. For your convenience, we have included updated
Unimodem V driver software on the disk that comes with the TAPI Phone.
Important: After loading the Unimodem V driver, you must reinstall any other modem driv-
ers loaded on the PC, so — before proceeding — please make sure you have all the
necessary software and documentation to reinstall those devices.
1.
If necessary, insert the TAPI diskette in the PC’s A: drive and open Windows Explorer.
2.
Select drive A: and single-click (do NOT double-click) on the file unimodv. This is a compressed
archive containing several files.
Note: If Explorer is set to show extensions, the file will appear as unimodv.exe.
3.
Click Edit ➜ Copy.
4.
Select the C: drive and open the System folder within the Windows folder. This is the subdirec-
tory c:\windows\system. Click Edit ➜ Paste. This will copy the unimodv archive into
c:\windows\system.
5.
Locate, and double-click on, unimodv (unimodv.exe) in c:\windows\system. This will extract the
files contained within the archive.
6.
After extraction is complete, locate and right-click on the file unimodv.inf in
c:\windows\system, and then click on Install. The PC will load the Unimodem V drivers.
7.
Restart the PC by clicking Start ➜ Shut Down ➜ Restart.
8.
After the PC has restarted, click Start ➜ Settings ➜ Control Panel.
9.
Double-click System.
Select the Device Manager tab.
Double-click Modems. You will see a list of all modems installed on the PC.
Remove each modem by clicking on it and then clicking Remove.
After all modems are removed, click Refresh.
10.
Click OK. You may now install the TAPI software from step 1 of that procedure (see page B.11).
(You may wish to re-install any modem drivers you removed, above, before continuing; it
doesn’t matter which comes first, the TAPI software installation or the modem driver re-
installation.)
Note: If you have difficulty reinstalling any modem, consult its manufacturer.
