Dear Jane,

I'm not familiar with this line but did a web search and found them at:

They have a number of user manuals available on line for the DMC1 at:

I looked into their troubleshooting guide at
and found on the top of page 3 the following:
Room station and or patio connectors are terminated
Short on intercom station cable runs.
Equipment or cable runs to close to AC lines.
Master is not on a dedicated 120 Volt 15 amp breaker.
Possible defective master.
Possible defective transformer.
If this list is exhausted, I would contact them directly at
They also have a link to a support forum on the contact page.
