2.3 Attention
Please pay attention to the following important items:
1. The PABX should be installed in a stable indoor place within a dry, ventilated environment. (Temperature
Range: 0-45, Humidity Range: 20%-80%. Avoid direct sunlight and flammable or caustic gas.) Use specialist
telephone cable to each phone socket.
2. A marginal space around the PABX should be allowed for heat dissipation, inspection and maintenance of the
system. The earth connection on the PABX protects against lightning strike and C.O. line noise.
3. Mount the unit on the wall. When wall-mounting the unit, avoid any contact between screws and the circuit
board inside the mainframe.
4. Please keep the PABX away from other equipment producing large electromagnetic disturbances (such as
motors, photo copiers, large transformers etc.).
5. Extensions should not be wired adjacent to any power supplies or antennas.
6. Avoid damaging the power-supply cable. Keep it away from water. If there is a water leak near the PABX turn
off the power immediately.
7. Please do not knock or shake the PABX in any situation. Do not dismantle the PABX whilst it is in operation.
2.4 Warning
1. The wiring should not be done during a thunderstorm.
2. Avoid using any telephone during a thunderstorm.
3. Please do not use any telephone where flammable or leaking gas is present.
4. Unless the equipment is disconnected, please do not touch any broken part of the extension wiring.
Notes: Lightning strike is an accident, which is not covered in your warranty.
C.O. Line means Central Office Line which is a term used for a BT (or other) line.

2.5 Installation Procedure
2.5.1 Connecting C.O. Lines & Extensions to the unit:
1. Please use any cables (optional) to connect BT C.O. lines and extensions separately.
2. If you are installing or using your own cabling, avoid short circuits.
3. Connect extensions to positions 601-608 and BT lines to LINE 1, 2 and 3 on the unit.
2.5.2 Power-on inspection:
1. The operation voltage of this product is AC220V or AC110V. In the UK, use the supplied power lead to
plug into the mains electricity.
2. A green flashing light on the PABX indicates normal power supply and operation of the unit.
3. Pick up the handset of extension 601. A sharper internal dial tone indicates that the system is
working normally. You can now start to setup the PABX.
2.6 Direct Access during Power Failure
The C.O. lines will be connected directly to Special Extensions automatically during power failure.
The No.1 C.O. line will be connected to Ext. 601, No.2 to Ext.602 and No.3 to Ext.603.
You can only use these three extensions as normal phones during power failure.
For example, when someone calls in on No.1 C.O. line at the time of a power failure, Ext.601 will ring - you
can only pick up Ext. 601 and talk with the caller. Hold and transfer features etc. will not work.
3. System Programming
3.1 Before programming
•All the programming must be carried out from the phone connected to extension 601; all the
programming must be carried out after the system is in programming status.
•All the phones connected to 601-608 must be dual tone multi-frequency.
•Enter a program instruction and end the process by simply pressing #. You don’t have to hang up
if something wrong occurs, you can press * to start again.
•If the programming extension 601 is set to Direct-Dialing-Out mode, you need to press * to enter
the internal system, before you can start programming.
•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. It is only after the end of the long beeps
that you can continue with another system operation.

the line.
Format: 163# Do not revert back to the originator.

Internal Call Ringing
Format: 494TT# (where TT is 01 to 99 seconds). Default is 30 seconds.
When one extension calls another and they do not answer, the phone will continue to ring

Transfer Ringing
Format: 496TT# (where TT is 01 to 99 seconds). Default is 25 seconds.
After a caller listens to OGM and selects an extension or when a call is transferred, the
system will ring the called extension for this set time.
You must set this time less than the Call Forward time.
