Plantronics CS50 and CS55 Headset Pairing Guide

Step 1

Ensure your Plantronics CS50 or CS55 charging base has power. Located in the back of the charging base is a “+” and “-“ button. Press these buttons at the same time and hold until the red LED light flashes in the front of the base, then release your fingers.

Step 3

Wait until the red LED turns solid and the green light on the earpiece goes out. Once this happens, your Plantronics CS50 or CS55 headset will now be paired and your headset should turn on.

Troubleshooting tips

  1. If your wireless earpiece and base don’t pair together, check to see if your wireless earpiece and charging base match model numbers. For example if you have a CS50 earpiece and want to pair this to a CS55 charging base, these won’t work together. To locate the model number on your charging base, turn your base upside down and you’ll see “CS50” or “CS55”. To find the model number of your earpiece, you’ll need to remove the battery door cover of your earpiece and remove the battery.
  2. Let your headset charge for at least 30 minutes before trying this pairing process. If your headset has been off the charger or hasn’t been charging, within 24 hours your battery won’t have a charge.
