Operating Button-Based Consoles
20 025-9535L
Console Features
Select/Unselect Speakers
The speaker and volume control on the left are for select audio. The speaker and volume
control on the right are for unselect audio.
Microphone
The Dispatch Console may be equipped with a handset, headset, desktop microphone, or
gooseneck microphone. Lifting the handset from its cradle or plugging the headset into its
jackbox usually causes the Select audio to be routed to the earpiece rather than the Select
speaker. Optionally, a
SPEAKER/H-SET button may be used to reroute the audio. The
jackbox has a volume control for the headset earpiece.
The handset and desk top microphone options have a built-in PTT (push to talk) button,
which when pressed, transmits on the Selected channel. Usually, the headset and
gooseneck mount microphone require the use of a foot-operated PTT or the
TRANSMIT
button on the console in order to transmit on the Selected channel.
Time/Message Display
The display on the Dispatch Console is normally used to show time in either a 12-hour or
a 24-hour format. The time shown is synchronized with any other consoles in the system.
In systems equipped with the ANI (Automatic Number Identification) option, the display
is also used to show the number of the calling unit. In the event of system changes (such as
a failure), the display may also show diagnostic messages.
If desired, the display can be programmed to show dashes only. For example, when a
facility master clock is used for time reference, this would be appropriate. Refer to the
Series 4000 Communication Control System Installation and Configuration Manual (P/N
025-9533) for programming information.
Level Meter
During transmit and intercom operation, the level meter (under the time display) shows
the level of your voice. During receive operation, the meter shows the level of the audio on
the Selected channel.
