To connect a Yealink WH62 headset to a Yealink T54W desk phone, follow these steps:

1. Check the Box Contents:
   
   • Ensure you have the base unit for the WH62, the headset itself, and the required cables (USB cable, power adapter, etc.).
2. Connect the Base Unit:
   
   • Plug the power adapter into the base unit of the WH62 and connect it to a power outlet.
   • Connect the USB cable from the base unit to the USB port on the Yealink T54W desk phone.
3. Configure the Phone:
   
   • On the T54W, press the Menu button, navigate to Settings, then Basic Settings, and select Bluetooth & USB.
   • Ensure USB mode is set to Headset. This setting allows the phone to recognize the WH62 as an audio device.
4. Pairing the Headset:
   
   • Once the base unit is powered on and connected to the T54W via USB, the headset should automatically pair with the base.
   • You may need to press the pairing button on the base unit to initiate pairing. Follow any additional prompts on the T54W screen if necessary.
5. Test the Connection:
   
   • Make a test call from the T54W desk phone to ensure the headset is working correctly. You should be able to hear audio through the headset and use its microphone for the call.
6. Adjust Settings if Needed:
   
   • You can adjust volume and other settings on the WH62 base unit or the T54W desk phone to ensure optimal audio quality.
