explained in the operating instructions. Improper adjustment of other controls may result in damage

For the PBX
•
Do not insert foreign objects of any kind into this product, as they may touch dangerous voltage points or
short out parts that could result in a fire or electric shock.
•
Do not pull, bend, rest objects on, or chafe the power cord and plug. Damage to the power cord or plug
can cause fire or electric shock.
•
Do not attempt to repair the power cord or plug. If the power cord or plug is damaged or frayed, contact
an authorised Panasonic Factory Service Centre for a replacement.
•
Do not leave the slot open if an option service card is not installed after removing a dummy cover plate.
Make sure to insert the slot cover included with the option service card into the slot.
•
When mounting the PBX on a 19-inch rack, only use the 19-inch rack mounting equipment (attachment
bracket, screws) made for use with the PBX.
•
If damage to the unit exposes any internal parts, disconnect the power supply cord immediately and return
the unit to your dealer.
•
To prevent fires, electric shock, injury, or damage to the product, be sure to follow these guidelines when
performing any wiring or cabling:
a.
Before performing any wiring or cabling, unplug the product's power cord from the outlet. After
completing all wiring and cabling, plug the power cord back into the outlet.
b.
When laying cables, do not bundle the product's power cord with the power cords of other devices.
c.
Do not place any objects on top of the cables connected to the PBX.
d.
When running cables along the floor, use protectors to prevent the cables from being stepped on.
e.
Do not run any cables under carpeting.
•
Unplug this unit from the AC outlet if it emits smoke, an abnormal smell or makes unusual noise. These
conditions can cause fire or electric shock. Confirm that smoke has stopped and contact an authorised
Panasonic Factory Service Centre.
•
Make sure that the wall that the unit will be attached to is made of concrete or thick wood, and is strong
enough to support the unit (approx. 35 kg). Do not attach the unit to walls made from plasterboard or thin
plywood. Attaching the unit to areas where there are strong winds, or where shocks or vibrations are
frequent or strong, may lead to the product falling over.
•
Only use the wall-mounting equipment (screws and washers) included with the PBX.
•
The earthing wire of the AC cable has an effect against external noise and lightning strikes, but it may not
be enough to protect the PBX and to ensure electromagnetic compatibility. A permanent connection
between earth and the earth terminal of the PBX must be made.
•
Proper earthing (connection to earth) is very important to reduce the risk to the user of electrocution or to
protect the PBX from the bad effects of external noise in the case of a lightning strike. (See "4.2.4 Frame
Earth Connection".)
•
Plug the power cord firmly into an AC outlet. Otherwise, it can cause fire or electric shock.
•
Be careful not to drop any components. Dropping components may damage them or cause an injury.
