Note: 
The IP phone should be used with Yealink original power adapter (5V/2A) only. The use of the third-party 
          power adapter may cause the damage to the phone. If you are connecting a PC to your phone, we 
          recommend that you use the Ethernet cable provided by Yealink.
          If inline power (PoE) is provided, you don’t need to connect the power adapter. Make sure the hub/switch 
          is PoE-compliant.
Note:
 
The USB port can also be used to connect Wi-Fi USB dongle WF40, color-screen expansion module EXP50 
          and USB headset. The Wi-Fi USB dongle WF40 and color-screen expansion module EXP50 should be 
          purchased separately. For more information on how to use the WF40 and EXP50, refer to Yealink Wi-Fi 
          USB Dongle WF40 User Guide and Yealink EXP50 User Guide. For more information on how to use USB
