Mute HDMI output audio: Output+M (example:Output1+M= Mute Output1 audio)
Lock Remote Control: short press ”W” to lock, short press again to unlock.
Turn OFF output channel: Output+X (example: Output1 + X= Output1 turns to a black screen, Output+X again to return to
normal)
Switching input left or right：Output + <(>) = the input source connecting to Output 1 will be switched to the previous or next
available input. For example- Input1,3 and 4 have signal and Output1 is now connecting to Input1. Press Output1 + >, this will
switch the source to Input3. Press it again and it will switch to Input4. Press it again and it will switch to Input1 ).
