How do you change the main display name on a Panasonic KX-T7453?

The KX-T7453 phone does not have a message function, you may have an associated voicemail on your system. Try dialing (on the intercom) extension 165 if you do not have a voicemail button. Are you trying to change the greeting for your individual phone or the main greeting people hear when they call your company?
This gets a lot more complicated and you should contact your vendor.

Try the instructions on the Panasonic Website. http://www2.panasonic.com/consumer-electronics/support/Phones-Fax/Business-Home-Systems/System-Phones/Digital-Super-Hybrid-Phones/model.KX-T7453.H

Press the * key to switch back to date and time. Also, the SHIFT button on top will change the STA EXT FEAT.

The only way I know of changing the name is in the main phone system.

Sign in to mailbox 999 and 998 and poke around. You should find some greetings in there. Else, if you have the installer software you can go in from that and make the changes.

Go into System Programming mode and choose location 004. Make the changes there.
