Go back How to subscribe or pair your Plantronics CS50-USB wireless headset to the charging base. Latest update: April 9, 2019 The CS50-USB wireless headset and charging base unit are originally subscribed or paired to each other. If your CS50-USB headset breaks or you loose it and a replacement headset is necessary, you will have to “re-subscribe” or “pair” the new CS50-USB headset to the base unit. This is a very simple process that takes only 2-3 minutes and a paper clip is required. The Subscription process is as follows: Step 1: Return the CS50-USB headset to the headset base / charging cradle. Step 2: Use a paper clip to push and hold the subscription button (located on the back of the base, just above the white sticker reading “CS50-USB” ) in for 5-10 seconds and then release. At this point the green light will flash on the base. Step 3: Press and hold the volume/mute button, located at the end of the headset, until the headset flashes with a green light. Successful re-subscription is indicated when the headset light is solid green and the red light on the base goes out. Note: If re-subscription fails within 2 minutes the headset will return to the un-subscribed state. Try the re-subscription process again.
