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 CO
lines:
a.
Disconnect the PBX from all CO lines.
b.
Connect known working SLTs to those CO lines.
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 CO line 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
CO lines until it has been serviced by an authorized Panasonic Factory Service Center.
