We had a power outage and have lost ringing on every phone appart from 1. We have had this before and program codes had to be put back in. Where can we get a copy of these codes to program?

Did you try unplugging power cord for five minutes? often this fix the problem.

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.

Press PROGRAM
Press *
Press #
Enter 2 digits (11 through 22)
Press INTERCOM

This should work.

DX-80 Comdial After power outage only Phone # 1 rings, i turned off for 1 min but no luck, any ideas?

Press feature key then dial #* password 000000 next, go to sets, hit show, hit next till ringing assingment is display hit show and change from n to y on line ringing assingment. do this for each set and line that need to ring.

3) press the line you wish to program
4) press the buttons for the extensions that you wish to ring (the ones in the right next to the handset)
5) press # when finished with the line
6) repeat steps 2 through 5 for the remainder of the lines you wish to change
The code for hold recall is #52
enter in your hold recall time in sec. and in a 3 digit format. i.e. 30 seconds = 030 a minute and a half is 090 and so on.
press # when finished

it sounds like the memory battery on the main board is no longer working which means that it'll happen again.

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.

There is a small battery inside your main control unit that keeps programming in memory during a power outage. The life of the battery is about 5 years give or take. When the system goes down for an extended period (or possibly several quick on/off cycles) your programming will be wiped out. By default, only a few telephones will ring. The battery is most likely a small blue 3-cell battery soldered right on the main board. It's not easily replaced. You can get a technician to replace it or hook up a standard battery backup unit (UPS) made for a computer. Your phone system uses less power than a computer so it can use any UPS and will last longer than advertised. Hard to say exactly how long. Just don't re-program the system until you take care of the problem or it will just default on you again.
