Connect and Configure Your Desk Phone
There are three setup options for connecting the CS540 to your desk phone. Select one of the
following and continue.
• Desk phone (standard)
• Desk phone + HL10 lifter (sold separately)
• Desk phone + EHS cable (sold separately)
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)
1 Connect one end of the telephone interface cable to the back of the base.
2 Disconnect the handset coil cord from the desk phone and re-connect it to the telephone
interface cable junction box.
3 Connect 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.
USE
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.
