Step 1
Plug 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 2
Plug in your phone cord that came included with the CS55 to the back of your Plantronics charging base.
Step 3
Unplug your desk phone handset from the base of your phone and plug it into the front of your Plantronics CS55 charging base.
Step 4
Plug 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.
Plug one end of the HL10 into your CS55 charging base.

Remove the double sided tape

Stick the Handset Lifter on the base of your phone
Lightly stick your HL10 Lifter down incase it needs to be readjusted.
