Telephone Company and F.C.C. Requirements and Responsibilities

Telephone Company and F.C.C. Requirements

and Responsibilities

1.Notification to the Telephone Company

Customers, before connecting terminal equipment to the telephone network, shall upon request of the Telephone Company, inform the Telephone Company of the particular line(s) to which such connection is made, the F.C.C. registration number (see the label on the bottom of the unit) and ringer equivalence number (REN) of the registered terminal equipment.

The REN is useful to determine the quantity of devices you may connect to your telephone line and still have all of those devices ring when your telephone number is called. In most, but not all areas, the sum of the REN's of all devices connected to one line should not exceed five (5.0). To be certain of the number of devices you may connect to your line, as determined by the REN, you should contact your local telephone company to determine the maximum REN for your calling area.

2.Connection to Telephone Line

This unit must not be connected to a coin operated line. If you are on a party line, check with your local telephone company.

3.Incidence of Harm to the Telephone Lines

Should terminal equipment cause harm to the telephone network, the telephone company shall, where practical, notify the customer that temporary discontinuance of service may be required.

However, where prior notice is not practical, the telephone company may temporarily discontinue service forthwith, if such action is reasonable in the circumstances. In case of such unnotified temporary discontinuance of service, the telephone company shall:

1)Promptly notify the customer of such temporary discontinuance of service.

2)Afford the customer the opportunity to correct the situation which gave rise to the temporary discontinuance.

3)Inform the customer of the right to bring a complaint to the Federal Communication Commission pursuant to the procedures set out in Subpart E of Part 68 of FCC Telephone Equipment Rules.

4.Compatibility of the Telephone Network and Terminal Equipment

a)Availability of telephone interface information.

Technical information concerning interface parameters and specifications not specified in FCC Rules, including the number of Ringers which may be connected to a particular telephone line, which is needed to permit Terminal Equipment to operate in a manner compatible with Telephone Company communications facilities, shall be provided by the Telephone Company upon customer's request.

b)Changes in Telephone Company Communications Facilities, Equipment, Operations and Procedures.

The Telephone Company may make changes in its communications facilities, equipment, operations or procedures, where such action is reasonably required in the operation of its business and is not inconsistent with the rules and regulations in FCC Part 68.

Telephone Company and F.C.C. Requirements and Responsibilities

If such changes can be reasonably expected to render any customer Terminal Equipment incompatible with Telephone Company Communications Facilities, or require modification or alteration of such Terminal Equipment, or otherwise materially affect its use or performance, the customer shall be given adequate notice in writing, to allow the customer an opportunity to maintain uninterrupted service.

Notify the Telephone Company

Installation must be performed by a qualified professional installer. If required, provide the telephone company with the following technical information:

•Telephone numbers to which the system will be connected

•Make: Panasonic

•Model: KX-TA1232

•FCC Registration No.: found on the bottom of the unit

•Ringer Equivalence No.: 0.4B

•Facility Interface Code: 02LS2

•Service Order Code: 9.0F, AS.2

•Required Network Interface Jack: RJ11 / 14C

Note

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

CAUTION

Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this device.

When programming emergency numbers and / or making test calls to emergency numbers:

1.Remain on the line and briefly explain to the dispatcher the reason for the call before hanging up.

2.Perform such activities in the off-peak hours, such as early morning hours or late evenings.

General Installation

2.1Before Installation

2.1.1Before 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:

a)Never install telephone wiring during a lightning storm.

b)Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

c)Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

d)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.)

a)In direct sunlight and hot, cold, or humid places. (Temperature range: 0 °C – 40 °C / 32 °F – 104 °F)

b)Sulfuric gases produced in areas where there are thermal springs, etc. may damage the equipment or contacts.

c)Places in which shocks or vibrations are frequent or strong.

d)Dusty places, or places where water or oil may come into contact with the system.

e)Near high-frequency generating devices such as sewing machines or electric welders.

f)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.)

g)Install at least 1.8 m (6 feet) away from radios and televisions. (Both the system and Panasonic proprietary telephones)

h)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:

a)To assure good quality telephone connection, it is recommended new and modifications to existing installation of customer premise wiring shall use solid twisted pair copper

28	Installation Manual

General Installation

conductors with minimum 24 gauge that comply with the electrical specifications for Category 3 wiring as detailed in ANSI/EIA/TIA-570A Building Wiring Standards.

b)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.

c)If cables are run on the floor, use protectors to prevent the wires from being stepped on. Avoid wiring under carpets.

d)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.

e)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-T7135, KX-T7130).

f)The Power Switch of the system must be off during wiring. After all of the wiring is completed, turn the Power Switch on.

g) Mis-wiring may cause the system to operate improperly. Refer to 3.1.1 Installation and 3.1.2 Connection.

h)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.

i)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.

j)Use twisted pair cable for outside line connection.
