The Plantronics CS540 is the lightest headset on the market. It features a streamlined design and professional performance with a talk time of up to 6 hours. With superior comfort, easy call management, and outstanding audio quality, the CS540 headset is a reliable device for many office and desk-centric workers.
An Electronic Hook Switch (EHS) cable allows the headset to engage the phone without having to remove the handset from the cradle. Electronic Hook Switch Cables (EHS) provide remote desk phone call control (answer/end) with your Plantronics wireless headset system
Follow the instructions below to connect your headset base unit to a desk phone using an Electronic Hook Switch (EHS) cable,
- Connect the end of the EHS cable to the back of the headset base unit.
- Connect the other end of the EHS cable to the desk phone as described in the EHS Adapter Getting Started guide that came with the cable.
NOTE: The desk phone and handset will continue to function like normal.
- Press the Call Control button on the headset to hear a dial tone.
- Dial a test call from the desk phone. If needed, fine tune the volume with the headset volume controls. You can also adjust the speaking and listening volumes on the desk phone.
NOTE: The minimum recommended separation distance between your desk phone and the headset base unit is 6 inches. Incorrect positioning may cause noise and interference problems that lead to poor audio quality.
