1.1 For Your Safety
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.
