1.1 For Your Safety
･ Make sure to install all necessary optional service cards in the PBX before performing the wall mounting
procedure. If it is necessary to install or remove a card, make sure to detach the PBX from the wall before
installing or removing the card.
･ When driving the screws into the wall, be careful to avoid touching any metal laths, wire laths or plates in
the wall.
･ Before opening the top cover, the AC power cord must be removed from the AC inlet.
･ Disconnect the AC power source before servicing the equipment.
・Do not open the front cover soon after turning off the power. There is a risk of receiving burns.
･ For safety reasons, close the top cover and tighten the screws before operating the PBX.
･ If the PBX is not installed properly using the securing correct methods, the PBX may fall causing serious
damage.
• When the PBX is placed on a desktop, make sure that the PBX is placed as indicated in "
the PBX on a Desktop". Do not place it on its side or upside down.
･ Performing surge protection is essential. Make sure to follow the instructions in
Installation".
• It is strongly recommended to use TLS encrypted communication when the PC is accessing the PBX via
the Internet. To use TLS encryption, routers must have a port set up for https communication.
･ Avoid using the same AC outlet for computers and other office equipment, as noise generated by such
equipment may hamper system performance or interrupt the system.
･ Unplug the system from its power source when wiring, and plug the system back in only after all wiring is
completed.
･ Trunks should be installed with surge protectors. For details, refer to
Installation".
･ When installing or removing the optional service cards, the power switch must be turned off, and the AC
power cord must be removed from the AC inlet.
･ For earthing wire, green-and-yellow insulation is required, and the cross-sectional area of the conductor
must be more than 0.75 mm2 or 18 AWG.
Notice
For All Telephone Equipment
･ Read and understand all instructions.
For the PBX
･ Keep the unit away from heating appliances and devices that generate electrical noise such as
fluorescent lamps, motors and televisions. These noise sources can interfere with the performance of
the PBX.
･ If you are having problems making calls to outside destinations, follow this procedure to test the trunks:
a. Disconnect the PBX from all trunks.
b. Connect known working SLTs to those trunks.
c. Make a call to an external destination using those SLTs.
If a call cannot be carried out correctly, there may be a problem with the trunk that the SLT is connected
to. Contact your telephone company.
If all SLTs operate properly, there may be a problem with your PBX. Do not reconnect the PBX to the
trunks until it has been serviced by an authorised Panasonic Factory Service Centre.
