My apologies for asking what is probably a stupid question, but how do I switch back and forth between my handset and Bluetooth headset OR between my handset and my Bluetooth speaker phone? The instructions to my new SuperTooth speaker phone says the following:

"keys on the phone can also be used to answer the call, but the audio will be in the phone. You can transfer the audio to SuperTooth by using the menu in the phone".

What is the "menu in the phone"?

I guess the same question is true for my Bluetooth Treo headset - how to I switch back and forth without having to power off the headset?

Much thanks,
