VP-81K - Operating Your VP-81K 8x1 UXGA/Audio Switcher 21

6.2.1 The Regular Switching Mode

You can set the machine to the regular switching mode by simultaneously
pressing and holding the VIDEO and INPUT 7 buttons for 2 seconds.
In the regular switching mode, all switching operations are performed manually.

6.2.2 The Automatic Switching Mode

You can set the machine to the automatic switching mode by simultaneously
pressing and holding the VIDEO and INPUT 8 buttons for 2 seconds.
In the automatic switching mode, the machine automatically switches to the lowest
active INPUT video channel which is connected.
The following examples clarify the automatic switching mode:
If input 6 is connected and active and input 4 is then connected (and active),
the machine automatically switches to input 4
If input 6 is connected but not active and input 7 is then connected and
active, the machine automatically switches to input 7 which is the active
input with the lowest number
If input 2 is active and connected and input 7 is then connected and active,
the machine remains switched to input 2 since it has the highest switching
priority (the lowest active and connected input number)
Other switching operations are performed manually.
6.3 Using the Audio-Follow-Video/Breakaway Modes
By default, the VP-81K switches in true audio-follow-video mode in which all
operations relate to both the video and audio. Both the VIDEO and the AUDIO
buttons illuminate in this mode.
