Front Panel Security Lockout (Executive Mode)

When front panel is locked, the front panel input and
Configuration buttons' functions are blocked. To toggle the
front panel lock on or off, press and hold down the Output and
Configuration buttons for more than 3 seconds. All LEDs flash
to indicate that the command has been accepted.
N When the front panel is locked, you still can view the tied
inputs by pressing the Outputs button to toggle between
the selection of output 1 and output 2.

Genlock Sync

When switching between inputs, the resulting image change
should be seamless and clean. The MMX switchers reference the
external sync signal on input #1 to synchronize switching during
the vertical interval. This allows vertical interval switching
between genlocked sources. Without the external sync locking
feature, switching between inputs can result in a brief rolling
(sync loss) or a brief change in the picture size.

System Reset

To reset the unit to factory defaults, press and hold the Config
button while power is applied. This resets the audio input
settings to unity (0 dB) and connects input 1 to outputs 1 and 2,
audio and video. The audio and video Config LEDs are lit.
Troubleshooting — If No Image Appears
1. Ensure that all devices are plugged in and powered on.
The switcher is receiving power if the Power LED is lit.
2. Ensure an active input and output are selected on the
MMX switcher.
3. Ensure that the proper signal format is supplied.
4. Check to see if the output is muted via an SIS command.
5. Check the cabling and make corrections as necessary.
6. Call the Extron S
necessary. See the rear cover of this manual for the phone
number in your region of the world.
