My Byron door bell has started ringing itself at random times - not welcome at three in the morning


It is NOT random.

You have a ghost visiting your house.

(or a little rats azz neighbor kid)

Replace any batteries. Low batteries can cause false rings in wireless doorbells, too.

I still think it is ghosts, however.

My doorbell and intercom are not working


I would suggest contacting ADT and tell them about what he did, and what problems have happened since that time and have them come back to correct them. This sounds like the repair person is not fully experienced with the work he did.

I get a fEE on my control panel after adding a 28-85 lens in addition there is a bell sound that keeps going off? What do I do to make it so that I can take photos with this lens?


If your lens has an aperture ring, do note that most of these lenses require the ring to be locked at a certain position for it to work. In the course of using the lens, you may have accidentally unlocked the aperture ring and moved it out of position. This is a common problem.

To fix this error, try this:

1. Turn off camera
2. Turn the aperture ring clockwise and then lock it
3. Turn on the camera

If you still encounter the same problem, repeat the same steps but turn the aperture ring counter-clockwise. Hope this helps.

MC 602 one of door bells rings intermitently.


I pulled the MC 602 from its wall case to examine wiring. Found a most unprofessional mess of wire connections. Cleaned up wiring and clipped the extra exposed shielding. Problem has not reoccurred, but time will tell it has sometimes been days between false rings.
