Audio 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 on audio models, 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. A more detailed
explanation of audio level adjustment is included in Viewing and adjusting the
audio level on pages 3-11 through 3-14.

Input and output label windows — These translucent panels can be removed
and replaced to insert labels behind the panels. To remove a panel, insert the
Phillips-head end of an Extron tweaker or small Phillips-head screwdriver
into the hole in one end of the panel, and gently slide the tab on the edge of
the panel out of the recess in the switcher housing.
Input and output labels can be created easily with Extron’s Button Label
Generator software, which ships with every Extron Matrix Switcher, or with
any Brother P-Touch labeler. Each input and output can be labeled with
names, alphanumeric characters, or even color bitmaps for easy and intuitive
input and output selection (figure 3-3). See Chapter 5, Matrix Software, for
details on using the label software.

Front Panel Operations
The following paragraphs detail the power up process and provide sample
procedures for creating ties, sets of ties, and configurations; changing a
configuration; viewing ties, sets of ties, and configurations; muting and unmuting
the video and audio; saving a preset; recalling a preset; and viewing and adjusting
the audio level.
Power
On all models, power is automatically applied when the power cord is connected to
an AC source. When AC power is applied, the switcher performs a self-test that
blinks the front panel LEDs during the test. An error-free power up self-test
sequence leaves the video and/or the Audio LED(s) on, depending on the model,
and all other LEDs off.
