When the time comes to replace your Plantronics CS50 battery, you will first need to order the battery. (Part number 64399-01 to order). When you’re ready to begin you will need a flat work space, a cloth or towel to work on so you don’t scratch your headset, a paper clip or small flat head screwdriver and 5-10 minutes of time. To start, simply follow the steps outlined below. When finished, place your headset in the base for a few hours allowing your new CS50 battery to charge.
*** IMPORTANT *** You need to apply significant pressure to both sides so you don’t break the small tabs under the cover. See step 4 picture to understand the location of the tabs
You’re half way done! Now reverse the steps to put the new battery back in, charge for a few hours and your CS50 will be as good as new.
