The only error code is that the Sony Clie SL10 "Searches..." then it pops up with "Could not find a receiving handheld computer

I had the same recurring problem with my T425 Clie, largely kept timing out, found the empeg about 1 in 4 times (albeit after a long negotiation).

Finally got frustrated and bought a cheap Palm Vx, works perfectly every time. Connects in 2 to 3 seconds max, anything from 0 to about 6” away.

Shame about the Clie, it had a nicer screen but its IR capabilities are not the same as the Palm. I assume your problem is the same. Sorry Dude!
