Installation and Maintenance Manual

Troubleshooting

All faults can normally be traced quite readily to a particular PCB. Prior to replacing any PCB, fault

conditions should be checked to see if they are caused by programming or mis-operation. The

Featurephone display will often indicate which system features have been set.

• System not initialising

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 divert.

• Extension outgoing locked

If you cannot get outgoing access on a 2-wire telephone, move a Featurephone to the extension. If it

shows EXTN LOCK, 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.

• Door intercom not operating

Check the programming for the door intercom.

• Phone reset

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

• System reset

Reset: To do a warm reset of the BT Versatility press the reset button on the CCU MDF. You may also

choose programming mode and choose system, reset options, and reset.

Reset to default: To do a cold reset of the BT Versatility, enter programming mode and choose system,

reset options, and reset to default.

This will reset ALL programming to factory default.
