I just worked it out.

Press Program
Then **
followed by your passcode (usually 1234)
Then 004
Then press next till you find Mark
Press Shift then the button under Clr
Then enter the name so for Claire start with 2 and swing the jog button round till you get a C, then press 5 and swing the jog button round till you get an l etc..
If you make a mistake press Transfer
Then when you've got your name correct press Auto Dial.

SOURCE: need to change extension numbers

Guessing you mean add or change extension numbers under the buttons, since you don't "add" or change extension numbers on the phone. From your set, press program dial 99 and the button you want to program. then , dial 1+ ext number and press STORE.

Do that for all the buttons you want to change then pick up the handset and drop it back down to exit programming.

How do i change the names on the extensions on my kx-dt343 so when i hit the button to call that line it shows the right name?

From the phone connected to extension 101, press PROG and dial **1234 If the display responds Sys Prog #, then dial 004 and enter. It's the menu to assign names to extensions. You can sort of follow along and use the arrows, the keypad, and the ENTER and SAVE buttons to step through the names and change them.

How do I toggle between day & night mode on the KXDT343

Toggle? What happens when you dial *7800 *7801 and *7802 from extension 101?

If you're manual switching, 7800 and 01 may "sort of" do the same thing. It's designed to drop the system back into the former mode waiting for the clock. 1 should be day absolute and 2 night.

Programming. An out of the box TDA system has only one phone programmed to ring, extension 101. The rest have to be put into ICD groups to "flash" or ring when a call comes in. That should have been done by the installer.

How do I turn on my message waiting light?

Why would you want to? Technically, I can turn on someone else's MW light in 2 ways, by calling them and dialing a "4", or by dialing *701 plus their extension number. That also means the equipment that's turning the MW lights on your phone has to do the same thing.

Before you ask, pressing the MESSAGE button and looking at the display where a soft key lets you CLEAR the message works, and *700 plus your extension clears ALL messages.

From that phone press PROGRAM and the button. What does the display say? If it doesn't say Ext XXX, then dial 1 plus the extension and STORE.

You should be able to read all the buttons and what is under them by just pressing them. Nothing changes until you press ENTER or STORE.
