    Press and hold the S-video output button for 2 seconds to mute the selected S-video output. N Since the video groups share the audio outputs, audio outputs can be muted in any video group. To avoid unwanted audio mute, select video only or audio only by pressing the I/O button before muting the selected output. N Mutes are saved to nonvolatile memory. When power is removed and restored, the mute settings are retained. N To view the mute status, it is recommended to select video only or audio only (I/O button) and toggle output buttons on any video group. The muted output LED will blink. N Selecting video & audio (I/O button) to view muted outputs is not recommended. Blinking output LEDs could also mean an audio or follow-all tie.
