It sounds as if you have DND - Do Not DISTURB
feature turned on...

There should be a light or indicator on the STATION itself
giving the DND status.

You don't. You program the System's ICD to delay ring the secondary phones. It can be done from the main system phone if allowed, but your Panasonic Installer can do it easier.

Obscurely you can make the main phone ring another phone as in Call Forward No Answer, but that creates a lot of trouble in the ability to go to voice mail and ring multiple phones.

Next time, press the MESSAGE button and look at the display. It will tell you where the message came from and one of the options will be CANCEL.

If you are using the KX-T7730 phone on a Panasonic KX-Txx 308 or 824 system.
From the Switchboard / Main telephone ( usually ext 101, 10 or 9 ) with the handset on the cradle/hook :
1. Press PROGRAM * # followed by the system password ( default is 1234).
2. Now press 604 and then SP-PHONE. Enter the jack number you wish to change ( 01 is extension 101, 02 is extension 102 etc. ).
3. Enter the name ( basically the same as texting on a cellphone ). Press AUTO DIAL / STORE to save your change.
4. To go to the next extension press SP-PHONE. Don’t forget to press AUTO DIAL / STORE to save your change after each name entered.
5. Press PROGRAM to exit program mode and you are done.

To change time on the KX-T7630 switchboard (using the TDA 100).
Press Progam or pause
Enter **
Enter your system password.

press cursor down one level - you will then see set date and time.

To exit the programming mode at anytime, lift the handset.

Hope this helps.

Panasonic KX-T7630 , to turn off the message light when their are no messages do the following.... go to the phone that the light is lit up....push Sp-phone.... enter *700 and the ext number.That should take care of the problem. :-)

Try *41 followed by extension number
OR *40 followed by group number eg 00 or 01
