2 Packing
Please check whether the packing contains the following or not.
The basic unit with handset
One cable
Standard 5V/1.5A power supply
IP0051 extension board (optional for wholesales)
3 Safety Information
You have two options for providing the IP0051 with power:
● Power over the Ethernet (IEE 802.3af compatible)
● An external power supply (5V/1.5A)
Warn: Non-factory power supply may cause the phone damage.
● First connect one end of the handset cable to the handset, and connect the other end to RJ11 port
on the phone’s left and bottom side.
● Plug the Ethernet (network) cable into the RJ45 connector labeled WAN, and the other end is
connected with internet or LAN.
● If you want to use labeled LAN port, use another Ethernet cable to connect PC with the phone’s
LAN port.
● If you are using an external power supply, get the standard 5V/1.5A power supply and connect
it to the phone’s power port; If you are using POE, just connect the Ethernet cable to the WAN
port, and the other end of cable is connected with the POE device.
● If you want to use a headset, connect the earphone(excluded in our packing) with the phone.
Please be sure the quality of the headset or the voice quality may be badly affected.
The numeric keypad with the keys 0 to 9, * , and # is used to enter digits and lettters. Depending
on the operating mode, different actions can be performed (see the table below):
