The remote device may not be powered up or may be out of range.

Click the down arrow in the Modem field and select the modem that will be used to dial out.
Click the "OK" button.
Click the "OK" button to close the Bluetooth Configuration Panel.

4. How do I determine the Bluetooth device address (BDA) of my hardware device?
In the Bluetooth configuration panel, on the Hardware tab, in the devices section, select the device for which you want to determine the address. In the device properties section of the dialog box, the fourth entry, device address, is the BDA of the selected Bluetooth device.

5. How do I determine the version number of the Bluetooth specification that the host controller interface (HCI) complies with?
In the Bluetooth Configuration Panel, on the Hardware tab, in the Device Properties section, the fifth entry provides Bluetooth Specification compliance information for the Host Controller Interface.
The sixth entry contains the Specification Revision information for the Host Controller Interface, if appropriate.

6. How do I determine the version number of the Link Manager Protocol (LMP)?

8. How do I test a network access connection?
If the client is hardwired to the LAN, unplug the hardwired connection to ensure that the test checks the wireless connection rather than the hardwired connection. If the server has access to the Internet, open a browser on the client and connect to the World Wide Web.

9. Why do I get an unknown port message when I attempt to use a Bluetooth serial port?
The "Unknown Port" error message usually means an attempt made to connect a port that was in use. Additional Bluetooth Serial Ports can be added if they are required.

10. Bluetooth Headset doesn't Always Function Under Windows 98
Windows 98 can not convert audio files with the extension m3u (e.g., myfile.m3u) into the Pulse Code Modulation (PCM) audio format used by Bluetooth headsets; this is a limitation of Windows 98.
Other versions of Windows (2000, ME and XP) can translate m3u audio files into the PCM format.
Possible solutions are:
Upgrade to a newer version of Windows
Use an m3u-to-mp3 conversion utility to convert the file(s) into a format that is supported by Windows 98. (Conversion utilities are available as freeware or shareware on the Internet.)
