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 re- quired 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

½a 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 the “Talk Button Latching/Non-Latching” instructions in Section 7 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 au- dio limiter in the beltpack is very tolerant of high input audio lev- els. 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 selec- tion. See the “Audio Channel A/B Enable/Disable” instruc- tions in Section 7 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 acti- vated. 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 the “Stage Announce Enable/Disable” instructions in Sec- tion 7 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” in- structions in Section 7 to learn how to enable/disable the WTA button as well as other features.
