How do I update the firmware on my Calisto P620 speakerphone?

Procedure

Note: This update is available for PC only.

To update the firmware on your Calisto P620 speakerphone:
  1. Connect the Calisto P620 to your PC using the USB cable (be sure the unit is powered on so Plantronics Update Manager can see it).
  2. Open Plantronics Update Manager, and if you do not have it set to automatically check for updates, click Check for Updates Now.
  3. Check the boxes for Plantronics Calisto P620 Base and Plantronics Calisto P620 USB, and then click Install Checked Updates.
  4. When prompted, unplug the USB cable from the device (and power cable, if connected) and then plug back in.
  5. Details on the new firmware version can be found under the About tab in the Plantronics Control Panel.
