N
When power is applied, the LEDs light sequentially from left to right. For first time power
up, the unit’s default configuration is input 1 tied to both outputs 1 and 2, the front panel is
not locked, and all states are unmuted. Input 1 LEDs for output 1 and for output 2 are both
lit. If this is not a first time power up, then the LEDs for the last valid input selections light.
Front panel security lock out (executive mode)
Locking the front panel protects the switcher from unwanted tampering. While the switcher is
locked, the user can select inputs only through a remote device.
To lock or unlock the front panel, press the following buttons simultaneously and hold them
for at least 3 seconds:
• For output 1 press and hold input 1 button. • For output 2 press and hold input 3 button.
The front panel LEDs flash to indicate that the
front panel is locked.
System reset
To reset the switcher to its factory settings, press and hold output 1’s input 3 button while
powering up the switcher.

When you selecting an input, the audio and video signals from that input are routed together
to the appropriate output.

Universal Switcher Control Program. When audio breakaway is active, the front panel input
LED for the audio source flashes, while the LED of the video source lights steadily.
