View button and LED — The View button selects a view-only mode that allows the display of the current configurations and provides a way to mute and unmute video and audio outputs. The view-only mode helps prevent changing configurations by accident. The View LED indicates that the switcher is in view-only mode.

In view-only mode, pressing any input button ( 1 ) or output ( 2 ) button lights the LEDs for the input and all outputs that are a part of that set of ties. Pressing the button for any unassigned output lights only the LEDs for all of the unassigned outputs. No input LED is lit.

As a secondary function on audio models, the View button decrements the audio level of the selected input. In audio adjustment mode, the View LED indicates a negative (-) attenuation value. A more detailed explanation of audio level adjustment is included in Viewing and adjusting the audio level on page 3-13.

Esc button and LED — The Esc button cancels operations or selections in progress and resets the front panel LEDs. The Esc button does not reset the current configuration, the Video and Audio LEDs, any presets, or any audio gain/attenuation settings. The Esc LED flashes once after the Esc button is pressed and released to indicate the escape function.

As a secondary function on audio models, the Esc button increments the audio level of the selected input. In audio adjustment mode, the Esc LED indicates a positive (+) gain value. A more detailed explanation of audio level adjustment is included in Viewing and adjusting the audio level on page 3-13.

Although present, the Audio button has no function on video only models.

7Video button and LED — The Video button selects and deselects video for a configuration that is being created or viewed. The Video LED lights to indicate that video is available for configuring or for viewing.

8Audio button and LED — The Audio button selects and deselects audio for a configuration that is being created or viewed. The Audio LED lights to indicate that the audio configuration follows the video configuration. The Audio LED blinks to indicate that the audio configuration is broken away from the video configuration.

As a secondary function, the Audio button selects the audio level display/ adjustment mode. Press and hold the Audio button until the Audio LED begins to blink. If the Video LED was lit, it turns off. Select an input. The current audio level setting for the selected input is displayed by the output LEDs. The audio level for the selected input can be increased and decreased by pressing the View ( 5 ) and Esc ( 6 ) buttons.
