Warning: if output video n°2 has been preset under the control of VCR trigger impulse, the keyboard will
not be able to control output n°2 and any manual attempt to switch the input to output 2 will have no effect. If the
VCR trigger function is not used to control output video n°2, set Use VCR: No for the item EXTERNAL
TRIGGERS in the OSM programming menu (for further details see the section on OSM programming of the
matrix).
The
