Beltpack Operation
Power / Local Headset Volume
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
½ 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 the “Talk
Button Latching/Non-Latching” instructions in Section 6 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.
