Introduction to TC-2000 system
TC-2000 Seires System is "Private Branch Exchange"(abbreviated as PBX), which is a Telephone System that switches
calls between users on internal telephone lines while allowing other users to share a certain number of external telephone lines
Fundamental Technical Information:
We integrate in this model special-purpose telecommunication ICs from American & Japanese companies, for lower
energy consumption, small size, compact appearance, disturbance resistance, high reliability, simple installation and
programming.

Chapter 2 Installation & Connection
Before Installation
For easy and quick installation and connection, it is strongly recommended that the user read and follow the following
instruction carefully so as not to damage the system accidentally by incorrect operation.
Safety Installation Instructions
When installing telephone wires, basic safety precautions should always be followed to reduce the risk of fire, electric
shock and injury to persons. Including the following:
1). Never install telephone wires during a lighting storm.
2). Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
3). Never touch UN-insulated telephone wires or terminals unless the telephone line has been disconnected at the
network interface.
4). Use caution when installing or modifying telephone lines.
Installation precautions
This set is exclusively made for wall mounting or set on desk. Avoid installing in the following places (Doing so may
result in malfunction, noise, or discoloration).
1). In direct sunlight, hot, cold, or humid places. (Temperature range: 0 C-40 C / 32F-104F)
2). Places in which shocks or vibrations are frequent or strong.
3). Dusty places, or places where water or oil may come into contact with the unit.
4). Near high-frequency generating devices such as sewing machines or electric welders.
5). On or near computers, telexes, or other office equipment, as well as microwave ovens or air conditioners ( It is
preferable not to install in the same room with the above equipment).
6). Install at least 6 feet from radios and televisions.
7). Do not obstruct area around the main unit (for reasons of maintenance and inspection be especially careful to allow
space for cooling above and at the sides of the main unit).
Power Failure
In the event of power fialure, CO.1 to CO.4 will be connected to EXT.801--804 automatically. But CO.5 & CO.6 can`t be
used for 6 CO line unit.
Before Installation
Call ID
FSK/DTMF compatible Caller ID function is successfully equipped on TC-2000 system. The steps are as below:
1). Go to your telecom office applying the Caller ID service.
2).
3). An incoming call number will be displayed on the phone with Caller ID function. But the number will disapper when
you transfer the call to another extension.
4). For some area the Caller ID function is invalid because of the Telecom Singal of the area.
Extension 801-808 can realize the caller ID function.

Connecting Procedures:
1. Connecting CO lines & extensions to the unit:
1). Please connect the monomer-crystal with EXT.
line and CO line separately;
2). Make sure to avoid short circuit;
3). Connecting extensions according to the in-
dicated extension positions and CO lines
to the correspanding line ports on the unit.
2. Zero-load power-on inspection:
1). The operation voltage of this product is
AC220V/110V 10%. Check out the voltage of
local power supply. A UPS backup is highly
recommended.
2). Plug in the power supply line and turn on
the switch; indicating normal power supply
and working state of the machine.
3). Pick up the handset of extension 801.A sharper
internal dial tone indicates that the system
is working normally.You can start to setup
operation now.

3 0 0 Remarks
3 0 0 1 All the function setting must be carried out on extension 801 and un-lock first;
3 0 0 2 All the extensions must be of double tone;
3 0 0 3 Press * to start setting and press # to end the setting. You don`t have to hang up if something wrong occurs
during the setting. You may restart the setting by simply pressing * again;
3 0 0 4 If extension 801 is in direct dialing out mode, you need to press * to enter the internal system, and press it
again to start programming;
3 0 0 5 When the setting is finished, a long beep indicates that the setting is done correctly and saved in the system.
If instead an array of short chirps is heard,that would indicate an error occurred in the setting. You need to
check it out and reset the system;
3 0 0 6 All the setting involved multiple users can be carried out in a batch process mode. It will surely increase the
speed and accuracy of the setting.

Description: Assigns the extensions, which will ring when incoming call from CO lines is received.
Example: If you wish extension 802 to ring from an incoming call for CO line 1, and extensions 803 and
806 to ring for CO line 2 incoming calls, then you may perform the following operation:
1>. The default ringing extensions are extensions 801 to 804;
2>. Ringing extensions must be among extensions 801 to 808;
3>. At most 8 extensions can be set to ring for one CO line, if the ringing extensions less than 8 then end
with #;
4>. The system must be unlocked before programming.(see 3.0.1.1)

can use the following commands:
3£®3 Set CO Line
Set CO Line
1>. Normally the order to set the CO line port is from port one to port two, port three ¡- one by one, but for
some situation you cloud ignore one port and jump from port one to port two (for the above example);
2>. For the CO line, you`d better set the incoming calls high-frequently-used one to the port of high position,
while for the out-going one to the low-position port;
3>. If the setting is wrong, you may hear nothing after dialing "0";
4>. The system can be used as internal communication system in case of no CO.line (You can input: * 3 # ).
