Switching between Stereo and Mono modes
The stereo/mono switch inside the control module allows the headset to be switched between stereo and mono mode. To switch between mono and stereo modes, slide the stereo/mono switch to "M" or "S" depending on the configuration of your panel. Refer to #12 in the photo.
The H2's stereo capability allows you to take advantage of a stereo-equipped intercom for rich, crisp audio. The H2 is also equipped with independent left and right volume controls so you can independently adjust volume levels in both the left and right ear.
