How do I switch using the Plantronics 510S between the desk phone and the cell phone during calls?
A. While on a call on your desk phone, you can dial a number on the cell phone and then press the Talk button on the headset to switch to the cell phone. You should now be hearing the audio from the cell phone. If you press the Talk button again, you will hang up the cell phone call. Pressing the Talk button once more will switch back to the desktop phone. If you are on a call on your desk phone and the cell phone rings, you can press the Talk button on the headset twice to switch to the cell phone. As before, if you press the Talk button again, you will hang up the cell phone call. Pressing the Talk button once more will switch back to the desktop phone. The original call should be still in progress.
