System Description
Introduction
The D-2475 Intercom System provides two-way audio
communications between a central station (called a Selector) and
several remote Call Stations. It is intended for use in service
stations, convenience stores, and other applications.
Modes of Operation The system has five modes of operation described below.
Standby Mode The system is in this mode when SBY is displayed.
The Standby mode occurs when no station is
connected, no key is pressed, and the Selector is
not in Off Line mode.
Listen Mode The system is in this mode when LIS is displayed.
The Listen mode occurs when a station is
connected and the Talk key is not pressed.
Inbound audio is emitted from the Selector.
Talk Mode The system is in this mode when TLK is displayed.
The Talk mode occurs when a station is connected
and the Talk key is pressed. Audio received at the
Selector microphone is transmitted.
All Call Mode The system is in this mode when ALL CALL is
displayed. The All Call mode occurs when the
ALL CALL key is pressed. The All Call mode
allows the Selector to simultaneously connect to all
Call Stations.
Off Line Mode The system is in this mode when OFF LINE is
displayed. In this mode, the Selector is powered
on, but is silent.
Hold Feature
The Hold feature allows an attendant to momentarily disconnect
from a call, greet a newer call, and return to the previous call.
