The Plantronics CS540 lifter may not be lifting due to the following reasons:
1. Cord Connection: Ensure the cord is firmly pushed into the handset lifter jack. 2. Positioning: The lifter must be correctly positioned under the handset for proper operation. 3. Phone Compatibility: The lifter works with both wireless and digital phone systems, but the phone must be tethered to the handset. 4. Power and Configuration: Verify that the headset base is properly connected and configured with the desk phone. 5. Mechanical Obstruction: Check if the lifter or handset is obstructed, preventing movement.
If the issue persists, additional troubleshooting or support from the manufacturer may be needed.

To pair (subscribe) a headset with the Plantronics CS540, follow these steps:
1. Dock the headset into the base. 2. The power/subscription light on the base will flash, indicating the pairing process has started. 3. When the light turns solid, the headset is successfully paired.
Only the last paired headset will work with the base.

While I am speaking on a call my headset keeps going on mute. It makes it very difficult to follow a conversation as I have to keep pressing the headset call button to come off mute. Any fix for this?

If your Plantronics CS540 headset is going on mute during calls, check if you are accidentally pressing the mute button. The mute button is activated by pressing the volume control straight in toward the microphone. Make sure you're not pressing this button while adjusting volume or handling the headset.
