How to Sync a New Plantronics Headset to an Old Base
- 1). Press and hold the two "Speak Volume Fine Adjust Buttons" simultaneously, located on the back of the base unit above the volume adjust switch. Release the buttons when the on-line indicator light (on the top of the unit) and the power indicator light (on the front of the unit) begin flashing.
- 2). Simultaneously press and hold the headset's "Volume Up" button and "Call Control" button. Release the two buttons when the status light flashes red and blue. The headset is in pairing mode.
- 3). Place the headset and base close to one another to allow them to communicate--no more than a few feet apart. Wait for the on-line indicator light on the base unit to stop flashing and light up solid blue. The headset status indicator light will also flash blue--this indicates pairing is complete.
