NOTE If you will be using a standard desk phone set-up or a desk phone with an HL10 lifter, continue below. If you will be using the desk phone with an EHS cable, refer to Desk phone plus EHS cable section in this guide. For further installation information, refer to the EHS Getting Started guide that came with your EHS cable or at plantronics.com/accessories.
Desk phone (standard)
1Connect one end of the telephone interface cable to the back of the base.
2Disconnect the handset coil cord from the desk phone and re-connect it to the telephone interface cable junction box.
3Connect the remaining end of the telephone interface cable into the open handset port on the desk phone.
NOTE Your desk phone handset will continue to work; it’s just hooked up differently.

NOTE If your phone has a built-in headset port, you should only use the headset port if you will not be using the HL10 lifter. In this configuration, you must press both the headset button on your phone and the call control button on the headset to answer or end calls.
