MESSAGE REPEATER CONNECTIONS
CONNECTING THE REPEATER TO THE PROGRAM INPUT
The PROGRAM Input provides a high level (1 Volt) balanced Input (10
K ohm) that may be used to connect to a MESSAGE REPEATER for
Messaging on Hold only through the telephone line.
1) Connect the Message Repeater Unit output to the Amplifier by fol-
lowing the diagram.
2) By referring to the MOH AMPLIFIER INPUT SOURCE SELECTOR
section instructions set the MOH SOURCE SELECTOR to PROGRAM
(be sure to follow the Caution recommendations).
3) Turn the PROGRAM Volume Control on the front panel to ZERO, this
will prevent the signal from the Repeater to reach the Main Amplifier
Output.
4) Adjust the MOH LEVEL CONTROL for the desired Output level to
the Telephone Line.
