If you're hearing a triple beep tone when you try to turn on your Plantronics CS50 or CS55 wireless headset, follow this quick pairing process.
Turn your Plantronics charging base around and press and hold the "+" "-"
sign at the same time, until the red LED light starts flashing in the front of the charging base, then release.
Press straight down and hold the mute button on your Plantronics CS50 or CS55 earpiece, until a solid green LED light appears, then release.
When the red LED light goes solid and the green light disappears on your Plantronics earpiece, your headset is now synced!
