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.
Step 1
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.
Step 2
Press straight down and hold the mute button on your Plantronics CS50 or CS55 earpiece, until a solid green LED light appears, then release.
Step 3
When the red LED light goes solid and the green light disappears on your Plantronics earpiece, your headset is now synced!
