Out of the box your Plantronics C054 (CS540) wireless headset system should automatically pair together between the charging base and microphone. In the case where your C054 microphone won’t turn on follow this quick manual pairing process below.
Located in the back of your C054 charging base is a button with two arrows pointing at each other (1). Press and hold this button for about 5 seconds until the white LED light flashes in the front, then release your finger.
On your C054 microphone, press straight up and hold on the volume control, until a white LED light appears on the earpiece, then release your finger
The LED light on the charging base will go solid and the white light on your earpiece will go out and the pairing process is done. You should now be able to turn your headset on
