4.1 Channel Buttons

After the KMU-300 is powered ON, you will only see one channel button illuminated red,
indicating that particular channel is the program channel (on air) and the button
corresponding to the preview channel should illuminate green. If you only see one channel
button illuminated red and the rest of the channel button LEDs are off, program and
preview channels share the same channel.
To switch the program channel to other channels, simply press the corresponding channel
button.
Note: only one channel can be activated as the program channel.
To select the preview channel using the channel button group, follow the steps below:
1. Press and hold the Program Channel (PGM) button, which is one of the four channel
buttons illuminated red.
2. Press other channel button to activate the Preview mode, and the channel button
should be illuminated green once pressed.
3. Release the Program Channel button after you have successfully selected the
Preview Channel.
