(See the instructions under Follow sub-mode below.) Press and hold the Program
Audio Mute button, then press and release the input button corresponding to the

Follow sub-mode
Within the Separate Switcher mode there is a special sub-mode called Follow
sub-mode. With the Follow sub-mode off (default), the switcher functions as
described above. With the Follow sub-mode on, when any input button is pressed
once, the input is routed to program audio.
To toggle the Follow sub-mode on or off, press and hold the Mode button for more
than 2 seconds until the front panel LEDs change to view mode, then press and
release the first button of the S-video/Audio group. S-video/Audio input #1 turns
on to indicate that Follow sub-mode is toggled on, or it turns off to indicate that
Follow sub-mode is off. Release the Mode button when your selection has been
made (the LED resumes input indication).
Program audio volume
Use the Program Audio Volume control knob to adjust the volume of the program
audio output. When the volume control knob is turned, the volume increases at a
rate of 1 dB per step of the digital potentiometer. Program audio volume does not
affect mic volume. Program audio volume has a range of 0 to 100.
Reset program audio volume
To reset the program audio volume to the default level (70), press and hold the
Mode button, then press and release the second button (labeled Prog Vol. Reset) of
the Video/Audio group within 2 seconds. Release the Mode button when the
volume has been reset.
