194 Operating Instructions
Possible Cause & Solution
•
The service for your telephone is turned off in the connected
PBX.
→
If the sub-display on the Feature Key screen or the
Calls screen (in Line Buttons mode) is blank, the service
status for your telephone is turned off in the PBX. Consult
your administrator to change the service status.
•
The phone number was entered incorrectly.
→
Confirm that you have entered the phone number of the
other party correctly.
→
Consult your administrator.
•
The screen was changed during a programming operation.
Under some conditions, changing the screen without exiting
programming mode can cause the KX-NT400 to not be able
to make and receive calls. This problem can occur when
programming the telephone via the Feature Key screen, the
Calls screen (in Line Buttons mode), or the Programming
screen.
→
Return to the screen where you were programming the
telephone. If programming mode is still active, press
EXIT until you have exited programming mode. You might
need to press EXIT more than once.
(Programming mode will also exit automatically after a
certain amount of time if it is left idle.)
•
The service for your telephone is turned off in the connected
PBX.
→
Consult your administrator to change the service status.
Note
•
The KX-NT400 turns off its service during certain
operations (importing/exporting data, refreshing the
directories, periodic refreshing). In some cases, it cannot
turn service back on after the operation has completed.
•
The number you are trying to redial is too long.
→
If the dialled number contains more than 32 digits for an
internal call, it cannot be redialled correctly.
•
Your telephone service does not allow you to make long
distance calls.
→
Make sure that you have subscribed to your telephone
company's long distance service.
•
If the KX-NT400 is connected to a PBX, your extension may
not be configured to make long distance phone calls.
→
Contact your administrator.
•
The ringer is turned off.
→
Press (UP) while a call is being received, or change the
ringer volume setting.
