TR-800 and TR-825 Top and Rear Panel
On/Off and Volume Control
Turn the beltpack power on by rotating the knob CW. Adjust the
volume to the headset by rotating the volume control as required
for a comfortable listening volume.
Battery Check
When the beltpack power is turned on by rotating the knob, the
BAT/OM LED will flash once if the battery is good. If the LED
stays on, the battery is low. If the LED does not flash, the battery
is dead.
Talk Button
Press the talk button to enable the audio path from the headset
microphone. The TALK/OM LED will turn red when audio is
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 held. If the talk function is latched on,
pressing the talk button again will turn it off. See “Talk Button
Latch on/Latch off” on page 57 to learn how to enable/disable
latching of the talk button.
Microphone Gain
Adjusts the headset’s microphone gain. Adjust so the TALK/
OM LED flashes red at the beginning of most words at normal
speech levels. If the input is too large, the LED will be red
during the complete word at normal speech level. The peak-
responding audio limiter in the beltpack is very tolerant of high
input audio levels. Even when the microphone gain is
maximized, and headset volume reduced to make up for the
louder audio, the audio will still sound good and not clipped.
Audio Channel Select Button
Selects the intercom system to which the headset is connected.
The LED near the channel button indicates the current selection.
See the “Audio Channel A or B Disable/Enable” on page 57 to
learn how to enable only channel
A, channel B, or both.
Stage Announce (SA)
When pressed the audio from the beltpack is routed directly to
the stage announce connector on the back of the base station.
The base station’s SA relay is also closed. The beltpack sidetone
is lost as an indication that stage announce is activated. The
other beltpacks and wired users do not hear this beltpacks audio
when SA is pressed. The button is non-latching and activates the
nearby red LED when pressed. See “Stage Announce Enable/
Disable” on page 56 to learn how to enable/disable the SA
button.
Wireless Talk Around (WTA)
When pressed, the audio from the beltpack 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 appropriate talk LED when pressed. See the
“Wireless Talk Around Enable/Disable” on page 56 to learn
how to enable/disable the WTA button as
well as other features.
