Front panel I/O label windows

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 Philips-head end of an Extron tweeker or small Philips-
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 3-2). See chapter 5 for details on
using the label software.

Front Panel Operations
The following paragraphs detail the power-up process and then 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.
The current configuration and all presets are saved in non-volatile memory.
When power is applied, the last current configuration is retrieved. The previous
presets remain intact.
If an error occurs during the self-test, the switcher locks up and will not operate.
If your switcher locks up on power-up, call the Extron S
