I bought a 6510 few days ago, but found I cannot connect my handset with my PC.

The PC can detect the handset through IrDA, but after about half a minute, it said the connection was interupted, though I did not move out the phone. This situation repeated again and again.

I tried many things after reading the recommendations from different people. For instance, I upgdated my Windows 2000 with SP3. I uninstall the PC Suite 4.51a program and its registry, then install it again. I also reduced the connection speed by step by step from 4000000 to 2400. But all these failed. Can any one help me?
