2 Overview
The new F4 color screen IP Phone is a high-end enterprise desktop phone which comes with an
intelligent DSS Key-mapping LCD to increase enterprise users’ productivity at a cost-effective price.
The DSS Key-mapping LCD is designed with intelligence to support dynamic usage to substitute
expansion modules. There are 6 DSS keys corresponded to the color LCD display to provide
dynamic Line/DSS/BLF functions up to five pages at virtualized total 30 DSS keys. User may
configure/customize each DSS key in each page. Every DSS key has a LED indication in green, red,
and yellow colors to reflect the key state. A page shortcut button is also designed to allow user to
quickly switch between pages. F4 is the most economic choice for SMB office and enterprise
supervisors.
F4 inherits all enterprise features from Fanvil’s C-Series enterprise phones, such as HD voice in
handset, headset, and full-duplex speakerphone modes, PoE, Fast/Gigabit Ethernet, QoS, secure
transmission, auto-provisioning, and more.
F4 is a great office productivity appliance for enterprise users. The old DSS key label is inconvenient
and not environmental friendly. F4’s intelligent DSS Key-mapping LCD provides users the flexibility
to change DSS key definition and display through easy configuration. Meanwhile, with its intelligent
design of the DSS key/LCD, it can be multiplied as expansion modules to save space and cost. F4
will provide the best user experience to advance enterprise users.”
In order to help some users who are interested to read every detail of the product, this user manual
is provided as a user’s reference guide. Still, the document might not be up to date with the newly
release software, so please kindly download updated the latest user manual from website, or
contact with support if you have any question using F4.

3 Installation
3.1Use PoE or external Power Adapter
F4, called as ‘the device’ hereafter, supports two power supply modes, power supply from external
power adapter and F4 supports 802.3af Class 2 Power over Ethernet (PoE) complied switch (PoE
support also applies to F4G).
PoE power supply saves the space and cost of providing the device additional power outlet. With a
PoE switch, the device can be powered through a single Ethernet cable which is also used for data
transmission. By attaching UPS system to PoE switch, the device can keep working at power outage
just like traditional PSTN telephone which is powered by the telephone line.
For users who do not have PoE equipment, the traditional power adaptor should be used. If the
device is connected to a PoE switch and power adapter at the same time, the power adapter will be
used in priority and will switch to PoE power supply at power failure on the power adapter.
Please use the power adapter supplied and the PoE switch met the specifications to ensure the
device worked properly.

5 Setting Up
In order to get the device ready for making and receiving phone calls, the device must be configured
with correct network configurations and at least one of the lines must be configured with an IP
telephony service.
5.1Network Configuration
The device relies on IP network connection to provide service. Unlike traditional phone system
based on a circuit switched wire technology, IP devices are connected to each other over the
network and exchange data in packet basis based on the devices’ IP address.
To enable the device, the network parameters must be configured properly first. To configure
network parameters, user should open the network configuration screen through soft-menu [Menu]
-> [Settings] -> [Advanced Settings] -> [Network] -> [Network Settings] from standby screen.
NOTICE! If user saw a ‘Network Disconnected’ icon flashing in the middle of screen, it
means the network cable was not correctly connected to the device’s network port. Please
check the cable is connected correctly to the device and to the network switch, router, or
modem.
There are three common IP configuration modes.
Dynamic Host Configuration Protocol (DHCP) –This is the automatic configuration mode by
getting network configurations from a DHCP server. Users need not to configure any
parameters manually. All configuration parameters will be getting from DHCP server and
applied to the device. This is recommended for most users.
Static IP Configuration –This option allows user to configure each IP parameters manually,
including IPAddress, Subnet Mask, Default Gateway, and DNS servers. This is usually used in
an office environment or by power users.
PPPoE –This option is often used by users who connect the device to a broadband modem or
router. To establish a PPPoE connection, user should configure username and password
provided by the service provider.

State of the art telecommunication products
The device is default configured in DHCP mode.
5.2Line Configurations
A line must be configured properly to be able to provide telephony service. The line configuration is
like a virtualized SIM card. Just like a SIM card on a mobile phone, it stores the service provider and
the account information used for registration and authentication. When the device is applied with the
configuration, it will register the device to the service provider with the server’s address and user’s
authentication as stored in the configurations.
To configure a line manually, user may open the line configuration screen through soft-menu button
[Menu] -> [Settings] -> [Advanced Settings] -> [Accounts] -> [SIP1] / [SIP2] / [SIP3] / [SIP4] -> [Basic
Settings] from the standby screen.
NOTICE! User must enter correct PIN code to be able to advanced settings to edit line
configuration. (The default PIN is 123)
The parameters and screens are listed in below pictures.
