How do i turn the ringer off of a phone - NorStar Meridian M7310 Phone

Ok, gotca.... no ringing at your set, as the title states.

First you need to know the extension of the phone that you want to change. Feature 0 at the phone and hit the intercom key to ensure that we are programming the right phone.

To get into programming press:
-> FEATURE 2 6 6 3 4 4
-> Password: 2 6 6 3 4 4
Now you will have to look at your LCD for 3 arrows
<- Heading..Enter->
<- Back .......Next->

-> you will now see TERMINALS&SETS and press Enter (the top right arrow key) now put in the extn that you want to change.
-> you should now see the extension number of the set and the name that is associated with it, press Enter (the top right arrow key) again
-> now you will see LINE ACCESS and press Enter (the top right arrow) again then LINE ASSIGNMENT and hit Enter again
-> then you will see Show line:____ and hit Scan the scan button
-> it will show something like L002: Appr&Ring now press CHANGE till it says Unassigned
-> keep hitting Scan till all the lines are found, DO NOT REMOVE ANY NUMBERS ABOVE 145, as these are your target lines for your Direct phone numbers (these numbers above 145 may not be there, but just incase)
-> after you find all the Lines, you now hit RLS to back out of programming.

Voila, your phone will not ring anymore except when you receive a direct call to your set -or- via your direct number if you have one.
