How to enter phone numbers into the memory/speed dial?

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

You will have to get into program mode for this. you will have to press this sequence of buttons. Hold*#*#1*2*3*. Password is default to 0000. Program number is 902 then press hold. Press Intercom button for Date and line 1 button for time. If you press Intercom #66 enter speed dial number 10-99 is station speed dial. If you press Intercom #66 and enter speed dial numbers 100-999 will be system speed dial. Hope this helps. I included a site below with program manuals.

Not knowing the specific model of the phone system itself (the PBX cabinet in the telephone closet) I would guess you are using the "personal directory" and it only has 10 number memory and it goes from 0-9. The system directory will give you more mems.

So I guess that means you're not programming SYSTEM speed dial numbers. Those are programmed from the system manager or operator's station. Personal speed dials are 1-0 and are programmed per set.

My Mom had this same problem.   I found these instructions on Uniden's website (uniden.com) under the "Owner Manuel" section.


Here you go - good luck!








Using the Speed Dial Memory 
Storing Numbers in Speed Dial Memory 
Your cordless phone can store up to ten numbers (up to 20 digits each) in the speed dial 
memory. To store number in memory: 
1) When the phone is in standby, press [memory]. The talk/batt low LED flashes. 
2) Use the keypad to enter the phone number. 
 (To enter a 2-second pause between numbers, press [redial/ 
pause]. Each pause counts as a digit. ) 
3) Press [memory] again. 
4) Select the speed dial location where you would like to store the 
number ( [0] to [9] ). You will hear a confirmation tone indicating 
that the number has been stored. 
NOTE: 
• Storing a number to a speed dial location will 
overwrite the any previously stored number without 
warning. 
• When storing numbers into memory and the handset is idle (i.e., no key is 
pressed) for more than 0 seconds, it will beep rapidly, and then the phone 
will return to standby. 
Dialing a Stored Number 
1) When the phone is in standby, press [talk], and listen for a dial tone. 
2) Press [memory] and enter the speed dial entry ([0] – [9]) that has the stored number 
you want to dial. (If you enter a digit that does not contain a stored number, the 
handset will beep rapidly, and the phone will not dial.) 
Chain Dialing 
The speed dial memory is not limited to phone numbers. You can store any number (up 
to 20 digits) that you need to enter once your call connects. This is referred to as Chain 
Dialing. An example is a frequently refilled prescription number. Store your pharmacy 
phone number in one speed dial and your most frequently refilled prescription number 
as another speed dial. To use, once you ring your pharmacy's automated prescription 
line, simply press [memory] and the speed dial number where you stored your account 
number. 
Erasing a Stored Number from Memory 
1) With the phone in standby, press [memory] twice. 
2) Press the number of the speed dial entry. A tone indicates that the stored number is 
erased from memory. 

I solved my problem by trial and error!
