Test Functions
The processor system automatically runs an initial self-test whenever the DTI 2000 is connected to the
mains. During this procedure, first the red DROP LED should light. Afterwards, the orange TALK
LED blinks for approximately 3 seconds. In case faulty operation is being recognized, the processor
system stops and the DROP and TALK LEDs light. Otherwise the
DROP LED is dimmed and only
the red DROP LED lights as long as a telephone connection has not been established.
Pressing the SEIZE / DROP button on the front panel manually establishes a connection (pick up) or
drops a connection (hang up). When the button is used to “take a call”, the green SEIZE LED should
light and the red DROP LED should be dimmed. Pressing the key once again drops the connection and
the red LED lights while the green LED is dimmed.
The orange TALK LED lights when the DTI 2000 is in announcement mode (i.e. when a telephone
announcement in a single or several zones of the PA-system has been activated).
