Extra Device Port (XDP)
Four extension jacks in the KX-TD308 support the connection of a
digital proprietary telephone and a single line device. The two
devices per jack have different extension numbers and are treated
as two completely different extensions.
Paralleled Telephone Connection
Every jack in the system also supports the parallel connection of a
proprietary telephone and a single line device. They share the same
extension number and are considered by the system to be one
extension.
Super Hybrid System
This system supports the connection of digital and analog
proprietary telephones, and single line devices such as standard
telephones, fax machines, and data 
term&&.
Digital Proprietary Telephones (DPT)
The system supports four different models of digital proprietary
telephones which cover the range from a monitor set to a large
display handsfree version.
Programming System
The system is programmed from a proprietary telephone.
Voice Mail Integration
The system supports Voice Processing Systems with in-band
DTMF signaling as well as DPT integration. The Panasonic Voice
Processing System provides automated attendant, voice mail,
interview and custom services.
Automatic Route Selection (ARS)
Automatically selects the pre-programmed least expensive route for
outgoing toll calls.l-2

							Section 2
Installation
This section contains the basic system installation and wiring
instructions, as well as how to install the optional cards and
units. 
						

							21aBefore InstallationPlease 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.
2-2Installation 
						

							210Before Installation
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.
4. Please use one pair telephone wire for extension connection of
(telephone) equipment such as standard telephones, data terminals,
answering machines, computers, voice processing systems, etc.,
except Panasonic proprietary telephones (e.g. 
RX-T7230, RX-
T7235).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 6.1.1 “Installation” and Section 
6.1.2 “Connection”.
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 lines should be installed with lightning protectors. For
details, refer to Section 2.3.2 “Outside Line Connection 
- Installing
Lightning Protectors”.
Warning:
Static sensitive devices are used.
To protect printed circuit boards
from static electricity, do not touch
connectors indicated to the right.
To discharge body static, touch
ground or wear a grounding strap.
Warning: Static sensitive connectorsInstallation
