If your Plantronics CS70n headset is giving you a triple beep tone and not turning on, follow this quick pairing process and your headset will be working like new again!
Step 1
Press and hold the "+" and "-" sign at the same time (located in the back of the charging base) until the red LED light starts flashing, then release.
Step 2
Press straight down and hold the "+" button on your CS70n earpiece until a solid orange LED light appears, then release.
Step 3
When the red LED light goes solid and the orange LED light disappears, your Plantronics CS70n earpiece is now synced to the charging base.
