Yealink recommends that you connect Bluetooth USB dongle or Wi-Fi USB dongle to the upper USB port, and connect
EXP43 to the lower USB port.
4. Connect the network and power, as shown below:
You have two options for network and power connections. Your system administrator will advise you which one to use.
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 adaper. Make sure the hub/switch is PoE-compliant.

After the IP phone is connected to the network and
supplied with power, it automatically begins the
