TR-800 Top Panel
1. On/Off & Volume Control – Turns the beltpack power
on and controls headset volume.
2. Wireless Talk Around (WTA) – When pressed, the
user’s audio is disconnected from the wired intercom,
auxiliary input/output and the base station’s local headset.
Other beltpack users, on that audio channel, can hear the
user as normal. The button activates the nearby red LED
as well as the Talk LED, #6, when pressed.
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 as well as the TALK LED, #6, when pressed.
4. Audio Channel Selection Button – Allows user to select
either audio channel A or B.
5. Bat/Overmod Light (BAT/OM) – 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 – LED is on when the talk button, SA or
WTA is active.
7. Talk Button – Press to enable the audio path from the
local headset microphone. The 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 a second will cause the audio path
to be enabled only for as long as the button is head. If the
talk function is latched on, pressing the talk button again
will turn it off.
