Front Panel Security Lockout
To prevent accidental changes to settings, the MLC features a front panel security lockout
mode for disabling access to controls. When front panel lockout is enabled, all the front
panel buttons are disabled. If a button is pressed, all the buttons flash rapidly three times
to indicate lockout, but no action occurs.
You can lock and unlock the front panel by the following methods:
• Front panel buttons
• The MLC configuration software (see the MLC 55, 62 and 64 Series Configuration
Program Help File ).
• SIS commands (see the
Front panel lockout
commands on page 61).
Locking Using the Front Panel Buttons
To lock the front panel using the buttons, press and hold the
On
and
Off
(top two) buttons simultaneously for 3 seconds. All the front panel
buttons and the red Activity LED flash three times rapidly.
To unlock the front panel, press and hold the
On
and
Off
buttons again
for 3 seconds. All front panel buttons flash three times slowly while the
Activity LED blinks green three times.
Resetting the MLC Using the Reset Button
If it becomes necessary to reset the MLC to its default factory firmware or to the default
configuration settings that were implemented at the factory, you can use either the
Reset
button (see below) or the configuration software (see the software help file).
The
Reset
button is located on the front panel of the MLC D behind the wallplate, and on
the rear panel of the MLC 62 RS EU and MK. To access the
Reset
button, do one of the
following, depending on your MLC model:
• Remove the wallplate from the MLC D (see Accessing the Covered MLC D Front
Panel Features on page 41), or
• Remove the MLC 62 RS EU or MLC 62 RS MK from the installation surface (see
Accessing MLC 62 RS EU and MLC 62 RS MK Side and Rear Panel Features
on page 42).
Use the provided Extron Tweeker or other small screwdriver to press the
Reset
button
(see figure 44,
1
).
