On/Off and Volume Control
– Turns beltpack power on
and controls headset volume for Intercom Channels A and
B. Either knob, A or B, turns the beltpack on. Both knobs
must be off to turn the beltpack off. If only one knob is off,
then only that Intercom Channel, A or B, is off for both
transmit and receive audio.
2.
Wireless Talk Around (WTA)
– When pressed, the user’s
audio is disconnected from the wired intercom, auxiliary
input/output and the base stations’s local headset. Other
beltpack users, on that audio channel, can hear the user as
normal. The default setting is software selectable, as to
which Intercom Channel, A, B, A+B, or currently selected
channel, is activated along with the WTA button. The WTA
button activates the nearby red LED as well as the software
selected Intercom Channel TALK LED if not already
active.
3.
Stage Announce (SA)
– When pressed, the user’s audio is
routed to the stage announce connector on the back of the
base station. The user also loses their sidetone as an
indication that stage announce is activated. The other
wireless beltpacks and wired users do not hear the user’s
audio. The button is non-latching and activates the nearby
red LED.
4.
Talk Button
– Press to enable the audio path to either
Intercom Channel A or B or A+B, from the local headset
microphone. The associated TALK LED, #6, will turn red
when enabled. A quick press and release latches the talk
function, unless latching has been disabled. Holding the
button for over 1/2 second, will cause the audio path to be
enabled only for as long as the button is held. If the talk
function is latched on, pressing the talk button again will
turn it off.
5.
Low Battery/Overmodulation (BAT/OM) Light
– Light
will flash once when unit is turned on if the battery is good.
If the light stays on, battery is low, If the light does not
flash, battery is dead. A normal microphone gain setting
will cause the LED to flash at the beginning of most words
at normal speech levels. If the gain is too high, the LED will
be red during the complete word at normal speech levels.
6.
Talk Light
– Will turn red when enabled by associated
TALK or WTA button.
