1 Basic System Construction
The KX-TA308 has a basic capacity of 8 extensions and 3 outside (CO) lines, and the
KX-TA616 has 16 extensions and 6 outside (CO) lines. It is capable of supporting
Panasonic analog proprietary telephones, and single line devices such as single line
telephones, facsimiles and data terminals.
To expand its capabilities, the system can be equipped with optional components or
customer-supplied peripherals such as an external speaker, external music source (e.g. a
radio) and door opener.

Section 2
Installation

2-2 Installation
2.1 Before Installation
Please read the following notes concerning installation and connection before installing the
system and terminal equipment.
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 system is designed for wall mounting only. Avoid installing in the following places.
(Doing so may result in malfunction, noise, or discoloration.)
1. In direct sunlight and hot, cold, or humid places. (Temperature range: 0 °C – 40 °C
{32 °F – 104 °F})
2. Sulfuric gases produced in areas where there are thermal springs, etc. may damage the
equipment or contacts.
3. Places in which shocks or vibrations are frequent or strong.
4. Dusty places, or places where water or oil may come into contact with the system.
5. Near high-frequency generating devices 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 system in the same room with the above
equipment.)
7. Install at least 1.8 m {6 feet} away from radios and televisions. (Both the system and
Panasonic proprietary telephones)
8. Do not obstruct area around the system (for reasons of maintenance and inspection — be
especially careful to allow space for cooling above and at the sides of the system).
Wiring Precautions
Be sure to follow these instructions when wiring the unit:
1. Do not wire the telephone cable in parallel with an AC power source, computer, telex, etc.
If the cables are run near those wires, shield the cables with metal tubing or use shielded
cables and ground the shields.
2. If cables are run on the floor, use protectors to prevent the wires from being stepped on.
Avoid wiring under carpets.
3. Avoid using the same power supply outlet for computers, telexes, and other office
equipment. Otherwise, the system operation may be interrupted by the induction noise
from such equipment.

2.1 Before Installation
4. Please use one pair telephone wire for extension connection of (telephone) equipment
such as single line telephones, data terminals, answering machines, computers, voice
processing systems, etc., except Panasonic proprietary telephones (e.g. KX-T7330).
5. Unplug the system during wiring. After all of the wiring is completed, plug in the
system.
6. Mis-wiring may cause the system to operate improperly. Refer to Section 6.1 “While
Installing” and Section 6.2 “While Connecting”.
7. If an extension does not operate properly, disconnect the telephone from the extension
line and then connect again, or turn off the Power Switch of the system and then on
again.
8. The system is equipped with a 3-wire grounding type plug. This is a safety feature. If
you are unable to insert the plug into the outlet, contact your electrician to replace your
obsolete outlet. Do not defeat the purpose of the grounding-type plug.
9. Outside (CO) lines should be installed with lightning protectors. For details, refer to
Section 2.7 “Outside (CO) Line Connection”, Installing Lightning Protectors.
