Help!

I have a Motorola H700 headset and when I try to connect it to my Treo 680 I get the following message:

"This phone cannot connect to: <Motorola H700> because another Hands-Free device is currently connected.

Disconnect the other device and try again"

I checked under Bluetooth, then under Setup Devices, then under Trusted Devices and it shows Motorola H700 as the device. I delete the device and try to reconnect and still have the same message as above.

Is there another way to find out what Hands-Free devices are connected to my phone?
