Inter-Tel EncoreCX
Installation & Maintenance Manual
Troubleshooting
All faults can normally be traced quite readily to a particular PCB. Before replacing any PCB, fault conditions
should be checked to see if programming or user mis -operation is the cause. The digital telephone display will
often indicate which system features have been s et.
System not initializing
Check that all system cards have been properly installed, with all connectors fully located.
No incoming calls
Check that all phones programmed to ring are not programmed for DND or Forwarding.
Extension outgoing locked
If you cannot get outgoing access on a two-wire telephone, move a digital telephone set to the extension. If it
shows "Unlock The Phone", the extension has been locked and you will need the unlock code to unlock it.
No extension dial tone
Check that the extension has not been disconnected through programming.
Not seizing a line for outgoing calls
§
Check if the line has been programmed for incoming calls only.
§
Check if the line is equipped in programming.

Check that the key is programmed for line access.

Phone reset
Remember the simple phone reset code 739, which can be dialed from any extension phone.
