How to subscribe or pair your Plantronics CS55 wireless headset to the charging base.

Latest update: July 14, 2019

The CS55 wireless headset and charging base unit are originally subscribed or paired to each other.  If your CS55 headset breaks or you loose it and a replacement headset is necessary, you will have to “re-subscribe” or “pair” the new CS55 headset to the base unit.  This is a very simple process that takes only 2-3 minutes and no tools are required.  Please be aware that if you have the CS55, you will need replacement headset model number 72195-03.  Although the CS50 and CS55 headsets look the same, they are not interchangeable. The Subscription process is as follows: 


Step 1:  Return the CS55 headset to the headset base / charging cradle.







Step 2:  On the back of the base unit, press and hold both of the microphone (talk) volume buttons (+ and -)for a minimum of 5 seconds.


The red power indicator light on the front of the base will then start to flash, when it does, let the buttons go.




Step 3:  Push in (down in the picture) and hold the black mute button for a minimum of 5 seconds (The mute button is located at the end of the headset).


The green light on the headset will then come on.





(Keep in mind that these 2 things need to be happening at the same time:  red light flashing &  green light illuminated on headset)

Successful re-subscription is indicated when the red power light stops flashing and is solid, and the light goes off on the headset.




Step 4:  The last step is to unplug the AC power adapter for 5 seconds, then reconnect.  You can do this by unplugging at the wall or the bottom of the base (as pictured).






Note:  If re-subscription fails within 2 minutes the CS55 headset will return to the un-subscribed state. Try the  re-subscription process again.
