Troubleshooting Your Intercom?

Help! My Intercom isn't working properly.

It's a brand new school year and you need to get things going, or you just got back from a long break and something is not right.  The Speakers are not loud enough, or they are humming. The announcement microphone is not working. Bell is not ringing. Sound is only on in one room.  The intercom is humming or only working for a short amount of time.
