On/Off & Volume Control
Turns the beltpack power on and controls headset volume.
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.
When pressed, the user’s audio is routed to the SA (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 nonlatching and activates the nearby red LED.
Audio Channel Select Button
Allows user to select either audio channel A or B.
Bat/Overmod Light (BAT/OM)
Light flashes 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 causes the LED to flash at the beginning of most words at normal speech levels. If the gain is too high, the LED is red during the complete word at normal speech levels.
LED is on when the talk button, SA or WTA is active.
The TALK LED, turns red when enabled. A quick press and release latches the talk function, unless latching has been disabled. Holding the button for over half a second causes 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 turns it off.
