How do I answer a call from my headset?
Is the headset paired with the phone you are using? If not, you can pair the headset by pushing and holding for a few seconds a small button on the back of the 5330 phone until it starts flashing. The button should be near the top of the cordless module. When the phone starts flashing, push and hold the answer button on the headset until it starts to flash as well. There should be a prompt on the phone itself to select which device you want to pair. Let me know if this helps :)
