We had power outage yesterday and now our office phones need re-programmed. We have Prostar 816. Since the power came back on, only one phone is ringing and the held calls are ringing back within a few seconds. We also cannot pick up phone to answer, we have to hit line that's ringing. How do we restore settings to the way they were? Only one phone is ringing in our office after a power outage. How do we get other phones to ring.
Did you try unplugging power cord for five minutes? often this fix the problem.
Your phone has no setting backup, to restore settings you need to reset the phone disconnecting it from power plug for few minutes, then you restore all settings one by one. To program again the phone you will need to follow instructions on manual for every single setting.

To change the ringing on a prostar 816 you first need to be at a display set (doesn't matter what the extension number is).
with the handset down enter #20 the screen should say MMC DISABLED
1) enter in 1 2 3 4 1 # (that enables programming)
2) enter in #62 the screen should say day ring assn
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.

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.

If you have a programming manual you can change the settings on your own. If not, you will need to contact the installer or a local interconnect company that services Samsung. It seems as though the memory switch inside the ksu is turned off. If that's the case, it needs to be turned on and if not, you either have problem with the ksu or the power outage was a brownout. Sometimes a very short loss of power can cause corruptions in memory, however I seriously doubt it in this case. Your system is acting as though it's memory has been set to default.
Good Luck,
