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.
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, "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.
