A voice message in the headset will say “headset #, battery full/half/low” and both
the power light and the transmit light will flash red. After a short time, the power
light will change to steady green for Lane 1, and the transmit light will go off. A voice
message will then say “Lane 1 (or 2).”

in the earpiece will say “headset off,” and the power light will go off.

you press the button you will hear a higher pitch beep in the earpiece as the volume

keep repeating rapidly until you release the button.

time you press the button you will hear a lower pitch beep in the earpiece as the

beeps will keep repeating rapidly until you release the button.
