Step 1Plug in the AC power and let your CS55 headset charge for about 3 hours for a full charge. *After setup if you get a triple beep tone, follow the CS55 pairing guide.
Step 2Plug in your phone cord that came included with the CS55 to the back of your Plantronics charging base.
Step 3Unplug your desk phone handset from the base of your phone and plug it into the front of your Plantronics CS55 charging base.
Step 4Plug the other end of your Plantronics phone cord into the HANDSET port of your desk phone.
Step 5- Setup your HL10 Handset Lifter
*Video will reference a straight plug connector to a different model of headset. The HL10 Lifter you need for the CS55 will be a right angle plug, so the charging base sits flush on your desk.
