After a series of power outages and brown outs over the weekend, our system has lost all of the predialed #'s and only one phone in the whole office (10 phone) rings.

All depends on who it was forwarded in the first place. Not enough details given.

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!

Hello. Often the aftermath of a power outage is a power surge. If your phone system is not surge protected, this is the likely culprit. The damage done by a surge or several surges can only be assessed with a thorough diagnostic exploration. This has to be done by a technician with the proper diagnostic equipment and know how. j.

Your system lost its programming. It will need to be reprogrammed completely. The lines are ringing on the extensions where I voicemail is, unplug voicemail and at least lines will ring in correctly.

The Privacy is part of FP1. You need to pick a button with a light, put the T/P switch in P, touch the button, dial *72, and put the switch back in the center position.

If that doesn't work, try Auto Ans Intercom or Do Not Disturb under the same button (*70,*71). If you can't get any of the features to work, I'm guessing that the FP cartridge needs to be replaced or power down the system and remove and insert the cartridge again.

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"

Your memory battery on your telephone system is bad. when power is lost , so is the programming. to fix this , you must go into system programming. From any phone, without picking up the handset. Press #20 Dial 12341, Press #. Press # again and dial 62, Press Line 1 and then press the button of each stn you want to ring ,( The display will show 1 if you press stn 1 and so on.) program each line the same way.

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.

I'm sorry there isn't. Answering machines like this have very little ROM memory. After a powersurge and outage like last night, it wiped the whole memory chip. You can try there support page. It's actually pretty good. http://telephones.att.com/telephones_ui/support/index.cfm
