Make sure to observe the instructions in this manual as the conventions of safety symbols and messages
regarded as very important precautions are included.
We also recommend you keep this instruction manual handy for future reference.
Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual first and
understand the safety symbols and messages so you are thoroughly aware of the potential safety
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
When the Unit is in Use
Should the following irregularity be found during
use, immediately switch off the power, disconnect
the power supply plug from the AC outlet and
contact your nearest dealer. Make no further ITC
attempt to operate the unit in this condition as this
may cause fire or electric shock.
If you detect smoke or a strange smell coming
from the unit.
If water or any metallic object gets into the unit
If the unit falls, or the unit case breaks
If the power supply cord is damaged (exposure of
the core, disconnection, etc.)
If it is malfunctioning (no tone sounds.)
To prevent a fire or electric shock, never open nor
remove the unit case as there are high voltage
components inside the unit. Refer all servicing to
your nearest dealer.ITC
Do not place cups, bowls, or other containers of
liquid or metallic objects on top of the unit. If they
accidentally spill into the unit, this may cause a fire
or electric shock.
Do not insert nor drop metallic objects or
flammable materials in the ventilation slots of the
unit's cover, as this may result in fire or electric
shock.
When Installing the Unit
Do not expose the unit to rain or an environment
where it may be splashed by water or other liquids,
as doing so may result in fire or electric shock.
Use the unit only with the voltage specified on the
unit. Using a voltage higher than that which is
specified may result in fire or electric shock.
Do not cut, kink, otherwise damage nor modify the
power supply cord. In addition, avoid using the
power cord in close proximity to heaters, and never
place heavy objects -- including the unit itself -- on
the power cord, as doing so may result in fire or
electric shock.
Be sure to replace the unit's terminal cover after
connection completion. Because high voltage is
applied to the speaker terminals, never touch these
terminals to avoid electric shock.
Be sure to ground to the safety ground (earth)
terminal to avoid electric shock. Never ground to a
gas pipe as a catastrophic disaster may result.
Avoid installing or mounting the unit in unstable
locations, such as on a rickety table or a slanted
surface. Doing so may result in the unit falling
down, causing personal injury and/or property
damage.
1. SAFETY PRECAUTIONS
1

An all-pole mains switch with a contact separation of at least 3 mm in each pole shall be incorporated in
the electrical installation of the building.
When the Unit is in Use
Do not place heavy objects on the unit as this may
cause it to fall or break which may result in
personal injury and/or property damage. In
addition, the object itself may fall off and cause
injury and/or damage.
Make sure that the volume control is set to
minimum position before power is switched on.
Loud noise produced at high volume when power is
switched on can impair hearing.
Do not operate the unit for an extended period of
time with the sound distorting. This is an indication
of a malfunction, which in turn can cause heat to
generate and result in a fire.
Contact your dealer as to the cleaning. If dust ITC
is allowed to accumulate in the unit over a long
period of time, a fire or damage to the unit may
result.
If dust accumulates on the power supply plug or in
the wall AC outlet, a fire may result. Clean it
periodically. In addition, insert the plug in the wall
outlet securely.
Switch off the power, and unplug the power supply
plug from the AC outlet for safety purposes when
cleaning or leaving the unit unused for 10 days or
more. Doing otherwise may cause a fire or electric
shock.
When Installing the Unit
Never plug in nor remove the power supply plug
with wet hands, as doing so may cause electric
shock.
When unplugging the power supply cord, be sure
to grasp the power supply plug; never pull on the
cord itself. Operating the unit with a damaged
power supply cord may cause a fire or electric
shock.
When moving the unit, be sure to remove its power
supply cord from the wall outlet. Moving the unit
with the power cord connected to the outlet may
cause damage to the power cord, resulting in fire or
electric shock. When removing the power cord, be
sure to hold its plug to pull.
Do not block the ventilation slots in the unit's cover.
Doing so may cause heat to build up inside the unit
and result in fire.
Avoid installing the unit in humid or dusty locations,
in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke or
steam as doing otherwise may result in fire or
electric shock.

5. TERMINAL CONFIGURATION OPERATING INSTRUCTIONS
The terminal needs to be configured before installation, before installation, need make a
installation plan including terminal name, terminal IP address, gateway IP address, server IP
address, location of terminal installation, and label the information on the terminal to ensure
the convenient use of the device. Please save the plan as an electronic document for future
maintenance. After the system planning is completed, please configure parameters of each
terminal includes “terminal IP address, subnet mask, gateway and server address”.
1.Installing software. Find the IP network broadcast system software installation package,
double-click to open it, click on the program “terminal configuration tool”, after the installation
of the program is completed, as shown below:
2.After the program is installed, a icon is generated on the desktop, as shown below:
3.Double-click the icon to run, and the “terminal configuration tool” window will pop up, as
shown below:

6
The configuration steps:
Step 1: Connect the terminal and the computer installed with the terminal configuration tool
program by the network wire, Plug in the power until the termianl power indicator is on.
Step 2: double-click to open the shortcut icon of “ terminal configuration tool”, select the network
card first, and left-click the “query” button in the window, to query the terminal’s original IP
address. Please pay attention to: local IP address of the computer should be set in the same
network segment as the terminal, because the default IP of terminal is : 192.168.168.166, so
the computer's local IP address should also be set to: 192.168.168.X, otherwise it maybe not
match the IP terminal address.
Step 3: In the window of “Terminal Configuration Tool” , fill in correct “IP address”, “Subnet
mask”, “Gateway IP” and “Server IP”, as below :
Step 4: left click on the “write” button, there will be a window prompt after the successful
configuration; after that, left click on the “query” button, the parameters of the terminal will be
re-read by the configuration program, if it display as the same as entered one, means that
the configuration was successful.
5. TERMINAL CONFIGURATION OPERATING INSTRUCTIONS

7
Step 5: If multiple terminals are in the same network segment, you only need to modify the
IP address of one terminal, it is needed to click on the terminal in the queried terminals list,
then cancel the choice of broadcast on the left interface, modify the IP address and click for
configuration.
Notes: If the terminal data can’t be queried or the network is blocked, the pop-up window will
say Reconfigure the IP address or IP adress writing error. In this case, please reconfigure
the network, check the network cable, and turn off the firewall, etc.
