To install a Pocket PC using Bluetooth technology

Attach or turn on the Bluetooth radio adapter for your Windows XP computer.
Set up your Pocket PC so that Windows XP can find it. Setting up your Pocket PC includes:
Turning it on
Making it discoverable (or visible)
Giving it a name (optional)
Open Bluetooth Devices in Control Panel.
On the Devices tab, click Add.
Follow the instructions in the Add Bluetooth Device Wizard to install your Pocket PC.
Before you close the wizard, write down the incoming COM (serial) port number that you see on the Finish page, because you will need it later.
Install the software that came with your Pocket PC, including the ActiveSync technology software.
Plug the Pocket PC into the USB cradle or connect it to the USB cable.
On your computer, in the Get Connected Wizard, follow the directions to automatically get connected. If the wizard does not appear, click Start, point to All Programs (or Programs if you are using the classic Start menu), and then click Microsoft ActiveSync.
On the File menu, click Get Connected.
On the File menu, click Connection Settings.
Select the Allow serial cable or infrared connection to this COM port check box, and then select the COM port. Read your Pocket PC documentation to determine which COM port to use. If one port does not work, try the other one.
Disconnect the USB cable from the computer.
On your Pocket PC, turn on the Bluetooth wireless technology.
To synchronize your computer and the Pocket PC using Bluetooth technology, follow the directions in the Pocket PC documentation.
