Your Leitner LH400, 500, or 600 series headset doesn't speak English in the traditional sense, but it will still try to communicate to you using a series of beeps and tones. Whether your battery is dying or your mute is on, here are some of the tones you can hear and what they mean.
If you are using a Leitner Premium Lite (LH200/300) series headset, then check out this Leitner beeps and tones article!
