How to change phone extentsions

You are basically setting up what extension teh phone is to use. Now you need to tell teh extension what user is going to use it.
If the phone says, no user, then there should be a login button. If there is not, contact the admin person so they can program one.

I need to display the time and date on this phone can you help mls-12d

Oh, so it displays a date and time, just not the CORRECT one?

From the phone connected to extension 10 or 11, press FEATURE the LIC (left intercom) twick and dial #101 Enter the date in MMDDYY format.

Day of the week is #102 if needed (2.0 or older software) with Sunday being 1, and the time is #103 in HHMM 24 hour format.

Pick up the handset2_bing.gif and drop it back in the cradle or press FEATURE to exit programming.

How do you reset the clock on the mls-12D?

You have to get into programming mode on the attendant station (usually x10 or x11) (see if you can find the programming overlay!) you know how to do that? If not then it's tricky stuff and you could mess up the system programming.

Program a code to dial out on the phone

I think you want a password setup. This is the owners manual for the phone and it should give you the info you need.
