If you are on a call and go out of the operating range, you will hear three low tones. You will
hear a single mid tone when you are back in range.
If you stay out of range, an active call will be suspended. The call will be re-established when
you walk back into range. If you remain out of range for more than 5 minutes, the headset will
drop the call.
