Possible Cause & Solution
•
System management may restrict certain features.
→
Consult your manager.

→
Confirm the revised number and try again.
•
The Intercom line was not seized.
→
The seized line, when going off-hook, was changed by
personal setting.
•
In the manual, going off-hook means an Intercom line is
seized.
→
If the setting has been changed, on the Programming
screen, press INT' or a PDN button after going off-hook
and follow the instructions.
•
The settings for the KX-NT400 have been changed via the PC

The KX-NT400 obtains its date and time information from the
PBX. Therefore, the date and time settings on the PBX are
incorrect.
→
Consult your administrator.
•
Another extension left you a message waiting indication while
you were on the phone or away from your desk.
→
Check the message waiting message.
•
On the PBX, the Incoming Call Log Memory setting for the
KX-NT400 is not set to 0.

Use the PC Maintenance Console to change the Incoming
Call Log Memory setting on the PBX to 0. For details, see
the PBX's documentation or consult your administrator.
•
A PDN button is not assigned on the extension corresponding
to your SDN button.
