Local Electrical outage has left our phone system void of all programming

If your system is out of contract and does not have any warranty left (because this will void any warranties on the phone), you need to use (https://www.kingoapp.com/) KingoRoot app to root your cell phone. Then use (System app remover (ROOT) by Jumobile Tools) to clean un-wanted apps. But, use this program to uninstall some or most of the applications (User & System Apps) that you do not need or do not use.

Call in a pro. it sounds like you lost all your programming with that power outage.
Depending on your processor type, you may have to re-program teh entire system, or just restore a backup....

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!

you will need to access system program mode to change ringing inmemory block 4-12

It sounds like the phone lost its programming of feature buttons. To reprogram them, press "Feature (star) 3" press the button to be programmed, and enter the feature code for the feature to be programmed:
Transfer -- Feature 70
Call Fwd (to mailbox) -- Feature 984
Call Fwd (to another ext.) -- Feature 4
Transfer caller to mailbox -- Feature 986
Page (general) -- Feature 60

Hope this helps!

Parviz3,

This unit sounds like it is like a computer that loads the program everytime it is turned on. When I am working on HD Video and I don't want to loose all the work I have been currently working on due to power outages, I put a UPS Battery Back up system on it that is capable of keeping my computer on for at least 30 minutes while things are being worked out.

This would be my suggestion for you. Buy an independant Battery back up power supply unit from a local store and be sure to get a medium sized one. I assume this phone system uses very little amperage and with such a battery back up system would stay on for days when your power is out. That would be the easiest solution and less time consuming for anyone at this point.

The battery is dead and will not maintain system programing after a power outage. If the battery is not replaced this problem will occur everytime the power goes out.

You need to know which phone system you have. Your Norstar phone can work on a few different Norstar phone systems that all set up and program differently.

Once you determine which system you have you need a "Programming and Installation" manual for the system NOT a "user guide"

This phone requires a phone system. The system itself stores the information. You need a programming and installation manual for your phone system, not the phone. You will need to determine the model number of your main phone system and look for the manual using that information. Phones only have user guides that explain how to use the features and do not get into programming the system.

Also, if you lost your programing in a power outage, most likely the memory battery is dead and this will keep happening in the future. Before making any programming changes, that battery needs to be replaced or you could possibly get away with a UPS battery backup system to power the entire phone system in a power outage.  

I have seen cases where programming can be messed up or even set back to default with rapid on-off-on-off power surges that often happen in power outages. The system will need to be re-programmed. I have never programmed an NEC system but here is what you need. Either find a local installation company that can fix this for you OR figure out which NEC phone system you have and locate the Programming and Installation manual for it. (not a user guide or administrator's manual) The phone's part number will not help you figure out which NEC system you have, it only narrows it down a bit. Look for the main control unit in the basement, utility closet, etc.. Programming any phone system can be daunting for someone who has not done it before even with the right manuals. If you are not up to it, look for a company that can help. MAKE SURE the system is defaulted before re-programming it! There could be a glitch in the programming that cannot be fixed without a system default so you want to do this before making any changes. Also, I would highly suggest a UPS backup power supply for the phone system. This will keep it running for a short time in a power outage and will stop this from happening again. If you have a small system with 1-12 phones, most small UPS systems made for computers will work. Small phone systems use less power than a computer and monitor.
