I have a Prostar 816 Plus. I disconnected the power cable today to connect it to a new battery back up surge protector. I then tried to dial out and it sounds like an old rotary phone. It allows me to dial out, but I can't input extensions to where I call due to the rotary phone characteristics. How can I reset or correct this problem?

root your phone and edit call ring delay in build.prop in the root of your phones system storage.

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

It's not called a Prostar in the UK but is known as the Samsung DCS 816. The follow clip will show you how to add to the system speed dial directory. But you can find 60+ handy clips at www.AbbeyTelecom.com

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.

Sounds like the system defaulted programming.
Depending on the type of prostar 616 the only ringing station would be 1(or 21) with the porstar or 4(or 24) with the prostar plus.
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
enter in 1 2 3 4 1 # (that enables programming)
enter in #62 the screen should say day ring assn
press the line you wish to program
press the buttons for the extensions that you wish to ring (the ones in the right next to the handset)
press # when finished with the line
repeat steps 2 through 5 for the remainder of the lines you wish to change
press # when finished.
To program system speed dial numbersyou need the customer programming enabled (see the first part of programing ringing)
press the ALM/SD button
dial the 2 digit speed dialcode 10-98
dial the telephone number to be stored in that speed dial bank
press ALM/SD to store the number

To change the time on a prostar 816 you first need to be at a display set (doesn't matter what the extension number is).

2) enter in #55 the screen should say YYMMDDWHHMM
3) enter in the year, month, day, day of the week, hours and minutes(the day of the week values are 1= mon. 2= tues. etc.)

Hi,


ENABLE CUSTOMER PROGRAMMING
 With the handset on-hook, dial #06. The display shows [MMC DISABLED].
 Dial the passcode and 1 and then press #.
At this point, customer programming is open. Follow instructions as needed.

TO SET TIME AND DATE::

Dial #55. Display shows [YY MM DD W HH MM].
Dial new information as follows:
YY = Last two digits of the year
MM = Month (01–12)
DD = Day of the month (01–31)
W = Day of the week (1–7; week begins on Monday and ends on
Sunday)
HH = Hour (use 24 hour clock)
MM = Minutes (00–59)
Dial # to set current date and time. The phone returns to normal use.

And here is the full operational manual:

hopefully it works for you.

First thing you should verify a dial tone on the fax machine. (use any analog phone)
If you have dial tone, press 9 and then a number
Second is it conected through tel. system? (did it have an internal extension) and there is no dial tone then your analog port may be fried. Call your telephone vendor. He should be able to help you.
You can purchase a manual for about 10 dollars
Email your system model number to sales at aaa-avad.com for further instructions

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.
