Intercom Power Status Lights (MS-704)
The four red short lights are failure indicators for each of the four intercom
lines. These lights will assist in locating a shorted or overloaded channel.
Within as little as ½ second of automatically cutting off power to an
overloaded intercom line, the MS-704 will attempt to turn power on again.
This allows momentary short or overload conditions to clear automatically.
Shorts are normally caused by miswiring or damaged cables. Overloads are
generally caused by connecting too many beltpacks and stations to an
intercom line.
Clear-Com’s advanced fail-safe design can sense the difference between a
short or an overload to optimally protect itself. Power is restored in as little as
½ second, depending upon whether there was a single or multiple short or
overload. The other channels continue to operate normally. The MS-704’s
advanced fail-safe circuit will bring the power back up even under full load
conditions. Front-panel lights indicate a fault on any of the four channels.
When the station is first turned on, all four short lights are normally off.
Selecting Microphones and Enabling the Speaker
To select the desired microphone, move the microphone select switch to the
appropriate position: either “panel” or “headset.”
The mic on pushbutton allows turning the microphone on or off. The mic on
pushbutton lights blue when the microphone is active.
The microphone will be turned on automatically whenever a talk function is
activated as it is assumed that you wish to talk. If one or more talks are active,
you may turn the microphone off without unlatching the active talks.
The speaker may be turned on and off with the speaker switch.
Listening to Intercom Channels
To listen to an intercom channel, press the listen button for the desired
channel. The listen button lights green to indicate that the listen function is on.
The listen level control (below the call button) for that channel is usually set
to full on position and the listening volume is set by the intercom volume
control to the left of the speaker.
