I have a treo 650 with earthlink. I bought a plantronics M3000 from Treo central. Works great except for one thing.

If I turn off bluetooth on my phone, or I turn off the headset, the link seems to be lost and I have to re-establish it. The phone looks like it's looking for the headset but it can't find it and reverts to directing the call via the handset.

The phone still says the headphone is one of it's trusted devices, but I have to go through the whole setup in the bluetooth settings app for discovering the headset and putting in an authorization code before it works again.

The reasons why I turn off bluetooth or the headset are obvious... to save battery life if I'm not going to use them for extended periods of time.

Any advice? TIA!
