How do i reprogram my norstar m7324 to change extensions names an

Hi J,

Do you mean how to make it ring when someone calls a specific phone number, or when someone calls the specific extension?

If for a phone number, then you need the line to appear and ring on the phone. Let me know which one you're doing.

For this problem contact the mobile service provider........

there's a manual on how to delete and add extensions

You must have an older system. There is a battery built into the control unit (not user replaceable) that stores the system programming in case of a power outage. When the battery is dead, your system will lose all programming and default to assigning the first 2 lines to all phones. The system will have to be completely reprogrammed.
Please Note: Now would be a good time to install a UPS/Battery Backup unit on the phone system. I recommend a large enough unit to keep the phones running for at minimum of 2 hours during a power outage. Install the UPS/BB first, and then reprogram the system (so it won't have to be reprogrammed twice). Good Luck!

The buttons will all have to be reprogrammed. Try this:
Press "Feature * 2", then press the button to be programmed, and enter an extension number. You will have to do this for each button.
Alternatively, you can unplug the phone for 1 minute, and plug it back in. The lights will start to flash on the phone, and stay solid on the KLM. When the lights begin to flash on the KLM, simultaneously press the bottom 2 buttons on the left-side and the bottom 2 buttons on the right-side of the KLM. This will cause each button to light momentarily from the top-left to the bottom-right, and will program the buttons, in ascending order, automatically from the first extension in the system until it uses all available buttons on the KLM.
Hope this helps!

And did the system default back to 2 lines? It probably lost programming, which will require a system technician or a very good end user to reprogram the whole thing.

Have fun.

It sounds like your service technician changed the Line Name to "dead" to let you & he know that line port was not working. Please check with your service company for further clarification.
Good Luck!

It sounds like you have a problem with your phone, possibly a stuck button. Have the phone repaired and/or refurbished.
