example, the pip that
confirms you pressed a
key echoes.
•
Data connections (yellow
and green wires) on one or
more command centers are
reversed, or only one wire
is connected.
•
Verify the yellow and green data wires are correctly connected
on all command centers.

monitor detects a phone line as
faulted.
•
Verify the telephone cord is correctly connected to the phone

Verify the Ground Start Jumper is in the correct position.
•
If using a ground start phone line, verify a D136 relay is
correctly installed in the Ground Start Relay socket.
•
Verify the phone jack (RJ31X or RJ38X) is wired correctly. The
incoming phone line must be wired to Terminals 4 and 5. The
in-house phone system must be wired to Terminals 1 and 8.
•
Verify all telephones are on-hook. Leaving a telephone on hold
after the other party hangs up creates an off-hook condition.
Verify there are no phones are on hold.
•

line, meter the line. If your readings are below 3.0 VDC,
contact your telephone company repair service.
