To delete the partnership I started ActiveSync and selected File, Mobile Device, and then Watson. Then I selected File, Delete Partnership. Note that you can only delete the current partnership in ActiveSync, which is why I had to switch to it first. Now we are good to go for creating the partnership. I lined up the IR port of Watson with the JetEye PC IR adapter and select Start, Programs, Communication, PC Link.
Communication quickly starts and synchronization occurs.
The brings to mind a gripe about the z50, the IR port is located on the right side of the device, and is not convenient at all. Any person designing a Windows CE Handheld PC who doesn't put the IR port on the back of the device, where God intended it, ought to be shown the door. All Palm-size and future Pocket PCs ought to have their IR ports at the top of the device. Fortunately, I have enough slack on the JetEye PC cable to line up the ports. BTW, if you sync multiple Windows CE devices with a desktop PC then JetEye is a must.
