How to Pair or Subscribe Your Plantronics CS55 Wireless Headset to the Charging Base KB103998


How to Pair or Subscribe Your Plantronics CS55 Wireless Headset to the Charging Base.

The CS55 Plantronics 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. You will first need to purchase the replacement CS55 headset. (Part number 72195-03 to order).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 and 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.
