Page Override
Page override is a special function in the station in which the intercom volume
defaults to a preset to a value when commanded to by the central matrix. Any
fixed group can be assigned the page-override function through the configuration
program.
The configuration program determines preset value for each station. If the preset
value is lower than the setting of the front-panel volume control, the volume will
be controlled by the front-panel control.
Mute Level
This turns down the speaker level when any talk is active at the station. The
amount of muting (measured in dB) is set by the configuration program for each
station. This function helps prevent possible feedback. The maximum amount of
muting is 15 dB below full volume. If the front panel control is set below that
level, then muting will have no effect.
Listen Level Adjustment
The level of any active listen path can be adjusted individually. Refer to
“Listen-Level Mode” on page 1-8.
Headset Connector
The headset connector provides a front-panel connection for a headset. Plugging
in a headset will initially cause the station to switch to headset-microphone
operation and will turn the speaker off. Unplugging the headset will cause the
station to switch to panel-microphone operation and will turn the speaker on.
Talk/Listen Selectors and Indicators
The following section describes the operation of the talk/listen selectors and their
associated indicators.
Selector Operation
The selectors operate as both talk and listen selectors; they also work as volume
controls when the station is in listen-level mode (see “Listen-Level Mode” on
page 1-8). Pressing a selector down accesses a talk label; pushing it up accesses a
listen label. Pushing the talk selector down and quickly releasing it will “latch”
the selector and the talk path will stay active until it is pressed again. Pressing and
holding a talk selector causes the talk path to stay active only for as long as it is
held down. Listen selectors operate in the same manner.
To prevent the selector on the station from latching in the talk position (local
latch disable), or to prevent any station from latching a talk to the station (global
latch disable) use the configuration program.
Talk and Listen Indicators
When a talk path is active, the selector’s red LED lights continuously. When a
listen path is active, the selector’s green LED lights continuously.
