Plantronics 620-M Connect PC and Call

1Power Speakerphone on.

2Insert Bluetooth USB adapter directly into your PC USB port. The LED will flash and then turn

solid blue to indicate the speakerphone is connected to the PC. The LED remains solid blue

when not on an active call.

NOTE Do not insert directly into a docking station or hub.

NOTE It is normal to see the LED flash at start-up before connection is established.

NOTE The Calisto 620-M works plug-and-play with Microsoft Lync/Office Communicator and

requires no drivers or additional software; however, the optional Plantronics Spokes software does

enable additional features. Please see the Plantronics Spokes Software section of this User Guide
