Be sure you understand the difference between a master code and the technician code. A master code lets you program other codes (and do some other harmless stuff). The technician code lets you do anything in the panel. If no master code is known you will need to default the panel. Do that by turning off power and disconnecting the battery. Reconnect the battery or plug pack and within 10 seconds enter 971300 on the code pad. That will wipe the eeprom back to factory defaults, and reinstate user 1 as a master code with a value of 1234. Don't even think of doing any of this without an INSTALLER manual. (Not the same thing as the USER manual). Better still, get an alarm tech familiar with DAS or CADDX products to program it for you. Worth every penny. After that you can add/delete users with your own master code using the much simpler User manual. Any code can be set to be a master code (that is you can have more than one master code)

Turn the commercial message on. It is an option as it wastes paper if you don't need it. Check the codes in machine features programming. The codes will depend upon the other settings you need within that that set of features. this is explained in the manual.
If you don't have the codes, they are in the manual here:

Here's the manual (.pdf file) for the Franklin "Merriam-Webster MWD-1450 Dictionary & Thesaurus
User's Guide", which has a "Games" key to get to the Franklin Games Menu, which hopefully
will let you use all the Games features of the WM 1200, since I can't find any evidence online that
a "WM 1200" exists.

Call Barring is a network feature. The Password for this feature is set by network. So don't need to worry. Just call your Network Service providers and ask them for the code, they will first authenticate you and will give you your code in return.
Note: Don't get spammed by someone telling you he can give you the code.

Hi! Your dehumidifier was made by Fedders for Maytag. However, Fedders as it used to be, not longer exist. It is now Airwell-Fedders. And they don't provide a download feature. However, you can call their Customer Service Dept 866-829-2440, and they may be able to email you a manual for your model. Be sure to have your correct model number handy, when you call.

Hope this helped you. Please let me know. Thanks.

If the extension was a swap of the old M7310 with a new(ish) M7310 no additional programming should be necessary. However if the phone was replaced with another type of nortel set(M7208, M7324,T7313 etc.) then the phone will default to its base features. To re-program the feature keys press feature *3, the button you wish to program, and the feature code for that button
