Precautions
• Keep the unit away from heating appliances and devices that generate electrical noise such as
fluorescent lamps, motors and televisions. These noise sources can interfere with the
performance of the PBX.
• This unit should be kept free of dust, moisture, high temperature (more than 40 ) and
vibration, and should not be exposed to direct sunlight.
• If you are having problems making calls to outside destinations, follow this procedure to test the
outside (CO) lines:
˚C
1. Disconnect the PBX from all outside (CO) lines.
2. Connect known working single line telephones (SLTs) to those outside (CO) lines.
3. Make a call to an external destination using those SLTs.
If a call cannot be carried out correctly, there may be a problem with the outside (CO) line that
the SLT is connected to. Contact your telephone company.
If all SLTs operate properly, there may be a problem with your PBX. Do not reconnect the PBX
to the outside (CO) lines until it has been serviced by an authorised Panasonic Factory Service
Centre.
• Wipe the unit with a soft cloth. Do not clean the unit with abrasive powders or with chemical
agents such as benzene or thinner.
For users in New Zealand only
• This equipment shall not be set to make automatic calls to the Telecom '111' Emergency Service.
• The grant of a Telepermit for any item of terminal equipment indicates only that Telecom has
accepted that the item complies with minimum conditions for connection to its network. It
indicates no endorsement of the product by Telecom, nor does it provide any sort of warranty.
Above all, it provides no assurance that any item will work correctly in all respects with another
item of Telepermitted equipment of a different make or model, nor does it imply that any product
is compatible with all of Telecom's network services.
• This equipment is not capable, under all operating conditions, of correct operation at the higher
speeds for which it is designed. Telecom will accept no responsibility should difficulties arise in
such circumstances.
• Some parameters required for compliance with Telecom's Telepermit requirements are
dependent on the equipment (PBX) associated with this modem. In order to operate within the
limits for compliance with Telecom's Specifications, the associated PBX equipment shall be set
to ensure that modem calls are answered between 3 and 30 seconds of receipt of ringing.
• IMPORTANT NOTICE
Under power failure conditions, the connected telephones may not operate. Please ensure that
a separate telephone, not dependent on local power, is available for emergency use.
For users in Taiwan only
• Lithium batteries can be found in the circuit boards of the main board and optional cards of the
PBX.

1.1 System Highlights
1.1.1 System Highlights
Fixed Line SMS Terminal Support (Optional Caller ID card required)
The PBX can relay incoming calls from a Short Message Service (SMS) centre to specific single line
telephones (SLTs) that support SMS. Fixed Line SMS is a service that allows text messages to be
sent and received via Public Switched Telephone Network (PSTN) access. We recommend using
SMS-enabled Panasonic SLTs.
Caller ID Display on SLT (Optional Caller ID card required)
The PBX can receive Caller ID information (telephone numbers and callers' names) from calls
received on outside (CO) lines. This information can be shown on the displays of SLTs that support
Caller ID as well as proprietary telephones (PTs) when receiving calls.
3-level Automated Attendant (AA)
3-level Automated Attendant (AA) service allows a caller to dial a single-digit number (Direct Inward
System Access [DISA] AA number) following the guidance of 3-level DISA outgoing messages
(OGMs), and be connected to the desired party automatically.
PC Programming
System programming settings can be accessed using a PC and the Panasonic KX-TEB308
Maintenance Console software as well as by using a PT.
The PBX software can be upgraded via the Serial Interface (RS-232C port) or USB port, using the
KX-TEB308 Maintenance Console software.
Quick Setup
Basic PBX parameters such as Automatic Configuration for Outside (CO) Line Type, Country Setting
can be programmed the first time the PBX is accessed with a PC using the KX-TEB308 Maintenance
Console software.
Advanced Hybrid System
This PBX supports the connection of PTs, Direct Station Selection (DSS) Consoles and single line
devices such as SLTs, fax machines, wireless telephones and data terminals.

Installation Manual 21
2.1 Before Installing
2.1 Before Installing
2.1.1 Before Installing
Please read the following notes concerning installation and connection before installing the PBX and
terminal equipment.
Be sure to comply with all applicable laws, regulations, and guidelines.
Safety Installation Instructions
When installing telephone wiring, 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 wiring during a lightning storm.
2. Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
3. Never touch uninsulated 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 PBX is designed for wall mounting only, and should be installed in a location where it is
accessible for inspections and maintenance.
To prevent malfunction, noise, or discolouration, avoid installing the PBX in the following locations:
1. In direct sunlight and hot, cold, or humid places. (Temperature range: 0 to 40 )
2. Areas where sulfuric gases may be present, such as near thermal springs.
3. Areas where shocks or vibrations are frequent or strong.
4. High-dust areas, or places the PBX may come into contact with water or oil.
5. Near devices that generate high frequencies, such as sewing machines or electric welders.
6. On or near computers, telexes, or other office equipment, as well as microwave ovens or air
conditioners. (It is preferable not to install the PBX in the same room as the above equipment.)
7. Within 1.8 m of radios and televisions. (Both the PBX and Panasonic proprietary telephones
should be at least 1.8 m away from such devices.)
8. Locations where other objects will obstruct the area around the PBX. Be especially careful to
leave at least 20 cm of space above and 10 cm to the sides of the PBX for ventilation.
Wiring Precautions
Be sure to follow these instructions when wiring the unit:
1. Do not run unshielded telephone cables near AC power cables, computer cables, AC power
sources, etc. When running cables near other noise-generating devices or cables, use shielded
telephone cables or shield the telephone cables with metal tubing.
2. If cables are run on the floor, use protectors to prevent the cables from being stepped on. Avoid
running cables under carpets.
3. Avoid using the same AC outlet for computers, telexes, and other office equipment, as noise
generated by such equipment may hamper system performance or interrupt the system.
˚C ˚C
22 Installation Manual
2.1 Before Installing
4. Use 2-pair telephone cables when connecting Panasonic proprietary telephones (PTs).
Use 1-pair telephone cables when connecting single line telephones (SLTs), data terminals,
answering machines, computers, voice processing systems, etc.
5. Unplug the PBX from its power source when wiring, and plug the PBX back in only after all wiring
is completed.
6. Mis-wiring may cause the PBX to operate improperly. Refer to Section 2, "Installation" when
wiring the PBX.
7. If an extension does not operate properly, disconnect the telephone from the extension line and
connect it again, or turn off the PBX using the power switch then turn it on again.
8. For safety purposes this unit is equipped with an earthed plug. If you do not have an earthed
outlet, please have one installed. Do not bypass this safety feature by tampering with the plug.
9. Use twisted pair cable for outside (CO) line connection.
10. Outside (CO) lines should be installed with surge protectors. For details, refer to "2.4.1
Connecting Outside (CO) Lines", "2.2.8 Installing Surge Protector".
WARNING
Static-sensitive devices are used in this PBX. To protect printed circuit boards
from static electricity, do not touch the connectors indicated below. To discharge
static electricity from your body, touch ground or wear an earthing strap.
