The IP phone should be used with Yealink original power adapter (5V/600mA) 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.
